Making Measurements in Voc Mode
Auto-hold
With the comparison display function, when the measured value
stabilizes, a short beep is emitted and the measured value is
automatically retained.
When the measured value is 20 V or higher and stabilizes for
approx. 1 second (fluctuation range is within 20 V), the measured
value is automatically retained.
When the test leads are disconnected from the measurement object
and a new measurement is started, the new measured value is
retained.
[HOLD] flashes: Waiting for stabilization of the measured value
[HOLD] appears: The measured value is retained
