Fieldpiece Probe Identification
Before pairing, identify which Fieldpiece probes you have. Each JobLink probe has a model number printed on the housing.
| Model | Name | Measures | Device Group | LED Color (Active) | Key Specs |
|---|---|---|---|---|---|
| JL3PC | Pipe Clamp | Line temperature | temperature_probes | Green | Range: -46C to 125C, Accuracy: +/-0.6C, 3-second response |
| JL3PR | Pressure Probe | Refrigerant pressure, saturation temp | manifold_gauges | Blue | Auto calibration, 45-degree angled fitting, elevation compensated |
| JL3RH | Psychrometer | Humidity, wet bulb, dew point | humidity_probe | Yellow | Range: -40C to 121C / 0-100% RH, 60-second response |
| JL3KM2 | Manometer | Static pressure, differential pressure | static_pressure | Orange | Dual port, high-accuracy differential measurement |
JobLink shared specs: 1,000+ ft wireless range, 150 hours battery life (AAA), IP55 water/dust resistance, operating temperature -4F to 122F. The patented copper pipe clamp design on the JL3PC eliminates ambient air interference, and the Rapid Rail sensor stabilizes in under 5 seconds. Complete Job Link Kit (2x JL3PC, 2x JL3PR, 2x JL3RH, JL3KM2, carrying case): $1,022.99.
SMAN manifolds (SM380V, SM482V) appear as a single device in measureQuick. Any probes physically connected to the manifold's ports report through the manifold, not as separate Bluetooth devices.
Fieldpiece Multimeter connects via BLE and reports amps, volts, capacitance, frequency, ohms, power, and temperature.
Section 1: Pairing JobLink Probes
JobLink probes are the most common Fieldpiece tools used with measureQuick. Fieldpiece was one of the first manufacturers to open full integration with measureQuick, enabling direct BLE connections for their entire probe ecosystem. As Jim Bergmann explained: "Fieldpiece sort of opened the doors for us to do our full integration, so we're able to do a lot with the probes." Each probe connects directly to the app via Bluetooth Low Energy (BLE).
Step 1: Power On the Probe
Turn on the JobLink probe by pressing and holding the power button for 2 seconds. The LED indicator lights up in the color listed in the table above. The probe enters pairing mode automatically when powered on and not connected to another device.
Step 2: Open measureQuick and Start a Project or Quick Test
From the home screen, start a new project or quick test. You need an active workflow to connect probes; measureQuick does not pair probes from the home screen.
Step 3: Open the Probe Manager
Tap the Probe Manager icon (the Bluetooth/probe icon in the workflow toolbar). This opens the list of available and connected probes.

Step 4: Scan for Available Probes
Tap Scan or Add Probe. measureQuick scans for nearby Bluetooth devices. Your Fieldpiece probe appears in the list with its model number and signal strength.

Step 5: Select the Probe and Assign It
Tap the probe name to connect. measureQuick prompts you to assign the probe to a measurement channel (for example, suction line temperature, liquid line temperature, or supply air temperature). Select the appropriate channel for your workflow.
What you'll see: The probe appears in your connected probes list with a live reading. The LED on the physical probe changes to a steady state, confirming the connection.

Step 6: Repeat for Additional Probes
Power on each additional probe and repeat Steps 4-5. measureQuick supports 15+ simultaneous Bluetooth connections. For a full cooling commissioning, you typically connect:
- 2x JL3PC pipe clamps (suction line, liquid line)
- 1x JL3PR pressure probe (or use an SMAN manifold for pressure)
- 1x JL3RH psychrometer (return air)
- 1x JL3KM2 manometer (static pressure)
Tip: Power on all probes before scanning. measureQuick finds them faster when they are already in pairing mode.
Section 2: Pairing SMAN Digital Manifolds
The Fieldpiece SMAN manifolds (SM380V and SM482V) act as a hub. The manifold connects to measureQuick as one Bluetooth device, and all probes physically attached to the manifold's ports report their readings through that connection.
SMAN Specifications
Fieldpiece offers four SMAN models: SM380V and SM382V (3-port), SM480V and SM482V (4-port). The SM382V and SM482V are the newer wireless variants. All share the same core specifications:
| Feature | 3-Port (SM380V / SM382V) | 4-Port (SM480V / SM482V) |
|---|---|---|
| Ports | 3-port | 4-port |
| Pressure range | 0-580 PSI (0-40 bar) | 0-580 PSI (0-40 bar) |
| Accuracy | +/-1 PSI | +/-1 PSI |
| Temperature range | -95F to 999.9F | -95F to 999.9F |
| Vacuum | 50-9,999 microns (+/-5% + 5 microns) | 50-9,999 microns (+/-5% + 5 microns) |
| A2L compatible | Yes | Yes |
| Display | 5-inch LCD | 5-inch LCD |
| JobLink range | Up to 1,000 ft line-of-sight | Up to 1,000 ft line-of-sight |
The SM482V is the recommended model for new purchases. Kits with HR3B hoses are available (SM382V kit: $713.99, SM482V kit: $974.99).
Step 1: Power On the SMAN
Press the power button on the manifold. Wait for the display to finish its startup sequence. The manifold's Bluetooth radio activates automatically.
Step 2: Attach Your Hoses and Probes
Connect your refrigerant hoses and any temperature clamps to the manifold's ports. The SMAN reads pressure directly from its internal transducers. Temperature clamps plugged into the manifold's thermocouple ports report through the manifold's Bluetooth connection.
Key point: When probes are physically connected to the SMAN, you do not pair those probes separately in measureQuick. The manifold sends all readings (pressure and temperature) as one device.
Step 3: Connect in measureQuick
- Open your project or quick test
- Open the Probe Manager
- Tap Scan
- The SMAN appears as "Fieldpiece SMAN" or by its model number
- Tap to connect

Step 4: Assign Measurement Channels
After connecting, measureQuick prompts you to assign the manifold's readings to channels. Typical assignments:
- High-side pressure to liquid line
- Low-side pressure to suction line
- Thermocouple port 1 to liquid line temperature
- Thermocouple port 2 to suction line temperature
What you'll see: Live pressure and temperature readings populate your workflow screen. The manifold's display and the app show matching values.

Using JobLink Probes Alongside the SMAN
You can use standalone JobLink probes at the same time as the SMAN. A common setup:
- SMAN handles refrigerant pressures and line temperatures
- JL3RH psychrometer handles return air humidity (connected separately via BLE)
- JL3KM2 manometer handles static pressure (connected separately via BLE)
Each device maintains its own Bluetooth connection. The SMAN does not relay data from wireless JobLink probes; it only passes through data from probes physically plugged into its ports.
Section 3: Pairing the Fieldpiece Multimeter
The Fieldpiece Multimeter connects via BLE and can also use WiFi. It covers electrical measurements: amps, volts, capacitance, frequency, ohms, power, and temperature. Two models are available:
| Model | Differentiator | Price |
|---|---|---|
| SC480 | Single temperature measurement | $373.15 |
| SC680 | Dual simultaneous temperature + swivel head for confined spaces | $443.70 |
Both models provide True RMS measurement with Type K thermocouple input and Bluetooth + Wi-Fi connectivity.
Step 1: Power On the Multimeter
Turn on the multimeter and select your measurement mode (volts, amps, etc.) using the dial.
Step 2: Enable Bluetooth on the Multimeter
Press the Bluetooth button on the multimeter. The Bluetooth icon appears on the multimeter's display, confirming it is discoverable.
Step 3: Connect in measureQuick
- Open your project or quick test
- Open the Probe Manager
- Tap Scan
- The Fieldpiece Multimeter appears in the available devices list
- Tap to connect and assign to the appropriate electrical measurement channel
What you'll see: Live electrical readings (amps, volts, or the active measurement mode) appear in your workflow.

Tip: The multimeter's measurement mode (volts, amps, ohms) is set on the physical dial. measureQuick reads whatever mode the dial is set to. Change modes on the multimeter itself, not in the app.
Section 4: JobLink Range vs. Standard BLE
The Fieldpiece JobLink system has a rated wireless range of up to 1,000 feet line-of-sight. Standard BLE range is typically 30-50 feet in field conditions.
| Factor | Standard BLE | JobLink System |
|---|---|---|
| Rated range | ~100 ft (30 ft typical in field) | 1,000 ft line-of-sight |
| Walls/obstacles | Significant signal loss | Better penetration, but still reduced |
| Practical field range | 15-30 ft reliably | 100-300 ft in most buildings |
Why this matters: You can leave your phone or tablet at the air handler while checking refrigerant readings at the condenser, even on larger homes. With standard BLE probes from other manufacturers, you may lose connection walking between indoor and outdoor units.
Realistic expectations: The 1,000-foot rating is line-of-sight in open air. In a residential setting with walls, ductwork, and equipment, expect 100-300 feet of reliable range. If you lose connection, move closer to the probes or reduce obstructions.

Tips & Common Issues
Probe does not appear in the scan list
Confirm the probe is powered on and not connected to another device. Fieldpiece probes connect to one device at a time. If the probe was previously connected to the Fieldpiece app or another phone, disconnect it there first. Power-cycle the probe (off, wait 5 seconds, on) to reset its pairing state.
Firmware updates required
Fieldpiece releases firmware updates for JobLink probes and SMAN manifolds through the Fieldpiece app (not measureQuick). If a probe behaves erratically or fails to connect, open the Fieldpiece app, connect the probe there, and check for firmware updates. Update all probes before returning to measureQuick.
SMAN manifold shows pressure but not temperature
Temperature clamps must be physically plugged into the SMAN's thermocouple ports. If the clamp is connected wirelessly as a standalone JobLink probe (JL3PC), it reports separately, not through the manifold. Check the port connections on the manifold itself.
Readings are inconsistent or drop intermittently
Move your phone or tablet closer to the probes. Even with JobLink's extended range, metal equipment, ductwork, and concrete walls reduce signal. Keep the device within 100 feet for the most reliable connection. Also check probe battery level; low batteries cause intermittent dropouts.
Connect/disconnect activity in the Probe Manager is normal
measureQuick dynamically connects and disconnects from Fieldpiece probes during workflows to save battery life on both your device and the probes. If you leave the app and return, or switch between workflow steps, you may see probes briefly disconnect and reconnect. This is expected behavior. The connect/disconnect cycle also helps extend battery life during longer service calls.
Use the Hold button for indoor/outdoor transitions
When moving between the indoor and outdoor unit, you may lose Bluetooth signal to probes left at the other location. Use the Hold button on the measurement screen to freeze current readings before walking away. Capture your measurements at one location, tap Hold, walk to the other unit, and continue. This is especially useful on multi-story buildings or homes with long distances between units.
Fieldpiece Wireless Scale (discontinued)
The Fieldpiece Wireless Scale (110 lb capacity, 33 ft BLE range) has been discontinued. If you already own one, it still works with measureQuick. Pair it the same way as any BLE probe (Probe Manager, Scan, Select, Assign). No firmware updates are available for the scale. For new purchases, consider the CPS Wireless Scale (220 lb capacity, 150 ft BLE range).
Multiple probes of the same type
If you have two JL3PC pipe clamps, measureQuick distinguishes them by their unique Bluetooth IDs. When scanning, the probes may appear with similar names. To tell them apart, power on one probe at a time, connect and assign it, then power on the second. Alternatively, note the last 4 characters of each probe's Bluetooth ID printed on the housing.
Probe Care and Identification
Tips from Joe Medosch's live training sessions on keeping Fieldpiece probes organized and in good condition.
Finding the serial number. The serial number is printed behind the battery door. If you need to identify a specific probe or report an issue to Fieldpiece support, check there.
Battery doors carry the probe identity. Mixing battery doors between probes of the same model swaps their identities in the app. The probe ID is stored in the battery door, not in the probe body. If you replace batteries on two JL3PC clamps at the same time and accidentally swap the doors, the app will see them as each other. Keep doors matched to their probes.
Labeling probes. Use heat shrink tubing to label probes (for example, "Suction" and "Liquid" on your two pipe clamps). Do not use adhesive tape, electrical tape, or scotch tape directly on probe housings or near sensor elements. Tape adhesive and the VOCs released by foam carrying cases can damage sensor elements over time. Joe's own psychrometer sensor failed from tape exposure; Jim Bergmann identified the damage immediately.
Probes connected in the Fieldpiece app will not connect in measureQuick
Fieldpiece probes maintain one active Bluetooth connection at a time. Close the Fieldpiece app (force-close, not just background) before scanning in measureQuick. On iOS, swipe up from the bottom and swipe the Fieldpiece app away. On Android, open Recent Apps and swipe the Fieldpiece app closed.
