I - Diagnostics & Interpretation
AI Assist: Voice and Text Diagnostics
What You'll Learn How to use voice and text interaction to get AI-powered diagnostic guidance from live measurement data How AI Assist differs from mQ Assist (I4) and why that distinction matters What the output categories are and how to read them ...
Modulating Equipment Analysis
What You'll Learn How modulating (variable-capacity) systems differ from two-stage and single-stage equipment Which inverter-driven equipment brands and models are common in the field Why standard superheat/subcooling diagnostics may not apply at ...
Two-Speed Compressor Diagnostics
What You'll Learn How two-stage compressors operate and why diagnostics differ between stages How to identify which stage is running during a test The correct testing protocol for two-stage systems in measureQuick How superheat, subcooling, and CTOA ...
Superheat/Subcooling Faults
What You'll Learn The common causes of high and low superheat, and how to distinguish between them The common causes of high and low subcooling, and how to distinguish between them How to use DTD, CTOA, and TESP alongside superheat and subcooling to ...
Combustion Analysis Results
What You'll Learn What measureQuick displays on the combustion results screen: CO, CO2, O2, stack temperature, draft pressure, and efficiency How to interpret ambient CO readings and when to escalate or evacuate How to interpret flue CO readings ...
Capacity Analysis
What You'll Learn What capacity means in practical terms: the BTU/hr of cooling or heating a system actually delivers How measureQuick calculates delivered capacity using the enthalpy method The difference between rated (nameplate) capacity and ...
Component Pressure Drops
What You'll Learn How to measure and interpret the pressure drop across each individual component: filter, indoor coil, return ductwork, and supply ductwork What typical pressure drop ranges are for each component and how they vary by system ...
Vitals Score Interpretation
What You'll Learn What the Vitals Score ranges mean: 90-100 (excellent), 70-89 (good), 50-69 (fair), below 50 (poor) How age adjustment works and what vitals_score, vitals_age_adjusted, and age_loss represent How subsystem results contribute to the ...
Target Zones
What You'll Learn What target zones are and why measureQuick uses color-coded ranges instead of single target values How the system profile (SEER rating, metering device, refrigerant type) determines the target ranges for each measurement How the ...
Red Flags Explained
What You'll Learn What a red flag indicates: the measurement falls outside the acceptable range for that subsystem Which of the 19 subsystems can show a red flag and what each evaluates The difference between measurement-based and subjective ...
mQ Assist (AI Diagnostics)
What You'll Learn What mQ Assist is and how it provides context-aware diagnostic guidance How mQ Assist differs from static pass/fail indicators - it analyzes relationships between measurements, not just individual thresholds When mQ Assist activates ...
Electrical Diagnostics
What You'll Learn What measureQuick measures electrically: voltage, amperage, wattage, and power factor How the electrical pass/fail subsystem evaluates performance The failure thresholds: voltage imbalance, over/under voltage, amp draw vs rated How ...
Fault Types: Minor vs Major
What You'll Learn How measureQuick classifies diagnostic faults into severity levels The difference between minor faults (single measurements slightly out of range) and major faults (significant deviations or compounding issues) How fault aggregation ...
Refrigerant Charge Diagnostics
What You'll Learn How measureQuick evaluates refrigerant charge based on metering device type What the pass/fail indicator means and how it is calculated What the field data shows: 56.0% of piston systems fail charge evaluation, 45.4% overall How ...
