Hold functions
Hold (HOLD)
Functions Stops display updates for all measured values and fixes the display values at that point
in time. Measurement data acquired by communications is also fixed at that point in
time. Peak exceeded and other warning lamps will still light up. Internal calculations (in-
cluding integration and integration elapsed time) will continue. Analog output and wave-
form output are not held.
Operation Pressing the HOLD key turns on the hold function (and causes the HOLD lamp to light
up). Pressing the HOLD key again turns off the hold function (causing the HOLD lamp
to turn off).
Backup Yes (when the instrument is turned back on, display of the initial data will be held)
Constraints During hold operation, the following operational constraints apply:
External control Input signal level 0 to 5 V (high-speed CMOS level) or shorted (low)/open (high)

: Setting and changes allowed -: Setting and changes not allowed
