Device and Measuring Parameters
rESoL – switching resolution
All main measuring functions can be switched back and forth bet-
ween 6000 and 60,000 digits.
1nFo
... SET rAtE ... resol
6000 / / 60000
(60,000 is the default setting)
0.diSP – show/hide leading zeros
This parameter determines whether or not leading zeros will
appear in the measured value display.
1nFo
...
SET rAtE ... 0.diSP
0000.0 : with leading zeros (default setting)
0.0 : leading zeros suppressed
A.diSP – analog display: select display mode
One of two different display modes can be selected for the
analog display:
• bArG: bar graph
• Point: pointer
1nFo
... SET rAtE ... A.diSP
bArG / Point
(bArG = default value)
APoFF – specified time for automatic shutdown and continuous ON
The instrument is switched off automatically if the measured value
remains unchanged for a long period of time, and if none of the
keys or the rotary switch have been activated before the specified
time “APoFF ” (entered in minutes) has elapsed.
If the on setting is selected, the multimeter is set to continuous
operation and
ON appears in the display to the right of the battery
symbol. In this case, the multimeter can only be switched off
manually. The „on “ setting can only be cancelled by changing the
respective parameter, or by switching the instrument off manually.
In this case, the parameter is reset to 10 minutes.
1nFo
... SET rAtE ... APoFF
10 ... 59 min on
(10 minutes = default setting)
dbrEF – measuring alternating voltage level
1nFo
... SET rAtE ... dbrEF
0 .. 001 ... 99 V
(0.775 V = default setting)
