What Is the Probe Manager?

The Probe Manager is the screen in measureQuick where you see every connected tool, its status, and which measurement slot it feeds. Think of it as the control panel for all your wireless instruments.

When you pair a smart tool via Bluetooth, it appears in the Probe Manager. From here you can:

• See which tools are actively connected and streaming data
• Check battery levels so you know before a tool dies mid-test
• Monitor signal strength to anticipate connection drops
• View and change which measurement channel each probe is assigned to
• See tools grouped by their device category

The Probe Manager is distinct from the Toolbox (where you initially add and pair tools). The Toolbox is for discovery and pairing. The Probe Manager is for monitoring and managing tools that are already part of your setup.

Accessing the Probe Manager

1. Open the measureQuick app.
2. Start or open a project.
3. From the diagnostic/gauge screen, tap the Probe Manager icon (typically shown as a grid or list icon in the toolbar area).

The Probe Manager can also be accessed from the hot menu during an active test. Tap the toolbar, then select Probe Manager.

Reading the Probe Manager Screen

Connection Status

Each tool in the Probe Manager shows one of three states:

measureQuick manages Bluetooth connections to save battery on both your phone and the tools. During certain workflow steps, the app intentionally disconnects from tools that are not needed. For example, during a gas furnace workflow, the combustion analyzer connects only when the combustion step activates, then disconnects when that step completes. Brief connect/disconnect cycles in the Probe Manager are normal.

Signal Strength

Signal strength appears as a bar indicator (similar to cell signal bars) next to each connected tool. More bars means a stronger Bluetooth connection.

Factors that reduce signal strength:

• Distance between the tool and your phone/tablet
• Metal ductwork, equipment cabinets, and concrete walls between tool and device
• Multiple Bluetooth devices competing for bandwidth in the same area

If signal drops to one bar or zero, expect intermittent data gaps. Move your phone closer to the tool or remove obstructions.

Battery Level

Each connected tool displays its remaining battery as a percentage or icon. Plan ahead: if a tool shows low battery before you start a test, swap batteries now rather than mid-test when you are capturing live data.

Battery endurance varies by tool. A Fieldpiece JobLink probe runs 150+ hours on AAA batteries. A Redfish iDVM550 runs on a 9V battery. Combustion analyzers consume more power and may need charging between jobs.

Channel Mapping

Channel mapping is how measureQuick knows which probe feeds which measurement. When you connect a pressure probe, the app needs to know: is this the high-side pressure or the low-side pressure? When you connect a temperature clamp, it needs to know: is this suction line temperature, liquid line temperature, supply air, or return air?

How Mapping Works

When you first connect a tool, measureQuick attempts to auto-map it based on the device type and available measurement slots. If you have a Fieldpiece SMAN manifold connected, its built-in sensors automatically map to high-side pressure, low-side pressure, and the associated temperature channels.

For standalone probes (individual temperature clamps, pressure probes, or psychrometers), measureQuick assigns them to the first available matching channel. If you connect two temperature clamps, the first one might map to "suction line temperature" and the second to "liquid line temperature." This default assignment may or may not match where you actually placed the clamps.

Viewing Current Assignments

In the Probe Manager, each probe entry shows:

• Tool name and model (e.g., "JL3PC Pipe Clamp #1")
• Assigned channel (e.g., "Suction Line Temperature")
• Current reading (e.g., "52.3F")

Reassigning Channels

If a probe is mapped to the wrong channel, tap on the probe entry in the Probe Manager. A list of available measurement slots appears. Select the correct channel.

Common reassignment scenarios:

• You connected temperature clamps before deploying them, and mQ assigned suction/liquid backwards. Swap the channel assignments in Probe Manager rather than physically moving the clamps.
• You added a second psychrometer for outdoor conditions, but mQ mapped it to the indoor humidity slot. Reassign it to the outdoor channel.
• You swapped a manometer from the return static position to the supply static position. Update the channel mapping to match.

After reassignment, the live reading immediately appears in the correct measurement slot on the gauge screen.

[Visual Reference] The channel reassignment dialog lists available measurement slots for the selected probe type. Tap the desired slot to reassign the probe. The live reading immediately appears in the correct position on the gauge screen.

Tip: Label your probes physically (colored tape, numbered stickers) so you know which probe is which before you open the Probe Manager. Fieldpiece JobLink probes support color bands for exactly this reason.

Device Groups

measureQuick organizes smart tools into device groups based on what they measure. Each group represents a category of instrumentation.

In the Probe Manager, tools are grouped by these categories. This helps you quickly see whether you have all the instrument types you need for a given test. For a cooling commissioning test, you need tools in at least the manifold, temperature, static pressure, and ideally electrical and humidity groups.

Some tools appear in multiple device groups. The Redfish iDVM510 multimeter, for example, maps to both "electrical measurement" and "temperature probes" because it includes a K-type thermocouple input.

Auto-Reconnection

measureQuick remembers previously paired tools. When you open the app with paired tools powered on and nearby, the app automatically attempts to reconnect. You do not need to go through the pairing process again.

Auto-reconnection behavior:

• Power on your tools before opening the project. This gives measureQuick the best chance of finding them immediately.
• Tools that were connected in your last session appear in the Probe Manager with their previous channel assignments intact.
• If a tool does not auto-reconnect within 30 seconds, check that the tool is powered on and within Bluetooth range. You can also tap the tool entry in the Probe Manager and select "Reconnect."
• Switching between devices (e.g., using mQ on your phone in the morning and your tablet in the afternoon): the tool will pair with whichever device initiates the connection first. It cannot connect to two devices simultaneously.

Probe Count: Connected vs. Physical

measureQuick tracks two different probe counts. Understanding the difference is important because it directly affects Vitals Score eligibility.

probe_count_connected

This is the total number of measurement channels receiving data, including:

• All physically connected Bluetooth instruments
• CALCULATED channels (e.g., subcooling and superheat derived from temperature + known refrigerant properties, without a physical pressure gauge)
• WEATHER channels (outdoor temperature pulled from internet weather data rather than a physical probe)

probe_count_physical

This counts only the channels fed by actual physical instruments. It excludes CALCULATED and WEATHER sources. This number reflects how many real instruments you have streaming data.

Why It Matters: Vitals Score Thresholds

The Vitals Score requires a minimum number of physical probes to produce a valid score:

• Cooling and heating tests: 9+ physical probes
• Gas furnace tests: 7+ physical probes

If your probe_count_physical is below these thresholds, measureQuick will not generate a Vitals Score for the test. The app needs enough independent data points to assess system performance with confidence.

A test with 6 physical probes and 3 CALCULATED channels has a probe_count_connected of 9 but a probe_count_physical of only 6. That test does not qualify for a cooling Vitals Score.

To reach 9 physical probes for a cooling test, a typical setup includes:

1. High-side pressure (manifold or wireless probe)
2. Low-side pressure (manifold or wireless probe)
3. Suction line temperature (pipe clamp)
4. Liquid line temperature (pipe clamp)
5. Supply air temperature (probe in register)
6. Return air temperature (probe at return)
7. Outdoor ambient temperature (probe or psychrometer)
8. Return air humidity (psychrometer)
9. Supply static pressure or return static pressure (manometer)

Adding more probes (both manometer ports, electrical meter, supply humidity, discharge line temp) strengthens the diagnostic picture further.

Tool Tracker V3 (New in 3.6)

measureQuick 3.6 introduces Tool Tracker V3, a GPS-based tool location feature accessible from within the Probe Manager's parent screen, the Toolbox. Tool Tracker records the last-known geolocation of every tool each time it connects via Bluetooth during a job. If a tool goes missing, you can see where it was last used on a map.

To access Tool Tracker:

1. Open the Toolbox.
2. Tap the Tool Tracker link at the bottom.
3. Tap Show All to display all tool locations on the map.
4. Tap an individual tool pin for details: last user, make/model/serial number, and the last-seen timestamp.
5. Tap Get This Address to retrieve the street address of the tool's last known location.

Tool Tracker is available to all paid users. For the full guide, see Tool Tracker (GPS Tool Location History).

Probe Manager Improvements in 3.6

• Alphabetized tool list. Tools in the Probe Manager are now sorted alphabetically, making it faster to locate a specific instrument when multiple tools are connected.
• Hide unused probes. A new toggle lets you hide probes that are not currently connected or streaming data. This reduces visual clutter when you have many tools in your Toolbox but only a few active on the current job.

Tips & Common Issues

Data shows up in Probe Manager but not on the gauge screen

Your probes are connected but not mapped to the correct measurement channels. Open the Probe Manager, find the probe showing data, and reassign it to the correct channel. This is one of the most common support questions. The probe is streaming data, but measureQuick does not know where to display it because the channel assignment is wrong.

I connected a new probe and it displaced my existing assignment

When you add a new probe of the same type (e.g., a second temperature clamp), measureQuick may reassign existing mappings. Check the Probe Manager after adding new tools to confirm all channels are still correct.

Probes do not show up when I tap "Add" or "Scan"

On Android devices, app permissions for Bluetooth and Location sometimes get turned off after a system update. Go to your device's Settings, find the measureQuick app, and confirm that Bluetooth and Location permissions are both enabled. On iOS, check Settings > Privacy > Bluetooth and confirm measureQuick is listed and toggled on. See Bluetooth Troubleshooting for a detailed walkthrough.

How many tools can I connect at once?

measureQuick supports 15+ simultaneous BLE connections. For a full commissioning setup (manifold, 4 temperature clamps, 2 psychrometers, 2 manometers, clamp meter, combustion analyzer), you are well within the connection limit.

A tool shows "Disconnected" even though it is powered on and nearby

Try these steps in order:

1. Toggle Bluetooth off and on in your phone's settings.
2. In the Probe Manager, tap the tool and select "Reconnect."
3. Power cycle the tool (off, wait 5 seconds, back on).
4. If none of the above work, remove the tool from the Toolbox and re-pair from scratch.
