Current and voltage can be measured with the 0554.0007 probe.
Note! If 2 probes are connected the signals must refer to the same reference potential. A
difference in potential is not permitted.
A different physical variable can be allocated to these signals in the main menu under PROBE -
S
CALING (See selection list). A separate configuration is possible for both probe connection sockets.
Scaling occurs once the channel and unit (confirm with ) have been selected:
e.g.: 0 to 20 mA should later correspond to 0 to 100 %RH in the display.
The right and left function buttons select the values, or
positions the cursor on the digit required, the digit is changed with
and
. The middle function button changes the previous
character. Scaling is confirmed by pressing
.
Number of digits after decimal point:
