Warnings & Error Codes
Critical Precautions
⚠️ Polarity Warning: Reverse connection will damage the meter.
⚠️ Power Sequence: ALWAYS power off source/load before connecting/disconnecting.
⚠️ High Temp Alert: Surface may heat during operation – do not touch.
⚠️ Operating Limits: Avoid short-circuit, overload, overvoltage (>34V), overcurrent (>30A).
