Measuring Inputs
All measuring inputs refer to ground and reference potential, P/COM input. The measuring
inputs are not electrically isolated from each other.
The measuring ranges depend on the respective measuring inputs.
Note!
600 V CAT III refers to measuring inputs S+, S− and P−/COM.
RFID Reader
The display is surrounded by an RFID reader. If individual batteries or the entire system are/is
equipped with an RFID tag, the tag can be scanned before measurement, thus making it
possible to subsequently assign the measurement data to the respective unit automatically.
The RFID reader can read RFID tags which use a frequency of 125 kHz (WorldTag™).
In order to read an RFID tag, hold the battery tester display 1 to 2 cm above the RFID tag.
“RF” appears at display.
