Input/Output/Measurement Specifications
Comparison display Displays the difference from the measurement
voltage with the auto-hold enabled for the first
time or immediately after reset.
Valid only in the auto-hold state.
Displayed range: −100 V to 100 V
Maximum count: 100 counts
Overrange display: [>100 V] or [<−100 V] is
displayed.
Auto-hold Setting method:
Enable by placing the instrument’s MEASURE
key in the raised position or press and hold the
MEASURE key on a test-lead with remote switch.
Functionality:
When both the below conditions are met,
measured value is automatically held.
• Measurement voltage: 20 V or higher
• Fluctuation range of measurement voltage for
1 second: 20 V or less
Auto-hold update: A signal meeting the above
Auto-hold conditions is input after a measurement
voltage less than 20 V is input.
