Hope Electronics Technology Manual Edition V1.0 39
Zero adjustment has failed
The buzzer sounds and [FAIL] appears. Then, the measurement screen
appears.
Zero adjustment has failed
When zero adjustment cannot be performed, the measured value before
zero adjustment already exceeds ±3% of the full scale of each range or the
instrument is in a measurement error state. Perform zero adjustment with
the correct wire connection again. If the resistance is too high (e.g., due to a
self-made cable), zero adjustment cannot be performed. In such a case, try
to minimize the wiring resistance.
Clearing zero adjustment
When the power is off, while holding the [0 ADJ] key, press the
[POWER] key to clear the zero adjustment for all ranges.
IMPORTANT
If zero adjustment fails, the zero adjustment is cleared for the current range.
