C OL x 0: On-line
1: Off-line
ON → ON, OFF → OFF: The state
remains unchanged.
OFF → ON: Proceeds to standby mode
for measurement in the main screen.
ON → OFF: No screen transition
Effective when the screen is in Mea-
surement. For other cases, the error
response (malfunction) returns.
Halt

hunting
C BR x x: channel number The measurement or calibration in Auto-
Hold is aborted.
In the measurement with AutoHold OFF
or in calibration, either calibration value
is forcefully obtained (in calibration), or
holds the measured value (in measure
-
ment).
In the interval memory, the error
response (malfunction) returns.
