Calibration Procedures
Calibrating Input Voltage
If your device displays incorrect voltage readings (up to 0.6V variance due to resistor tolerances):- Measure actual input voltage with a multimeter
- Connect power to your device
- Enter Settings menu
- Navigate to Advanced settings
- Select Calibrate input voltage
- Use
+/Aand-/Bto adjust displayed voltage to match your measurement - Press both buttons together to save and exit
Calibration is only needed if you experience cutoff issues. Weak power supplies may also trigger cutoff warnings.
Calibrating Tip CJC (Cold Junction Compensation)
Only calibrate if:- Tip temperature is significantly higher than displayed
- Tips are wearing out prematurely
- Delta between target and measured temperature exceeds 5°C
- Power on your device
- Go to Advanced Settings → Calibrate CJC at next boot
- Confirm with
+/Ato accept the warning - Exit settings menu (hold
-/B) - Unplug your device
- Critical: Ensure tip is attached and wait until both tip and handle reach room temperature
- Power on the device (ideally keep it on desk, not in hand)
- Display shows
