WARNING

 

Use the RS232 serial port only after disconnecting the high voltage input.

 

This communication port can only be used to program the module. Z-NET or Easy Setup are our 

configuration software. The RS 232 serial port uses the following communication parameters: 

2400,8,N,1.

 

During the use of the RS232 port, the bus will be inactive; it will reactivate automatically a few seconds 

after the last message exchanged on the COM port. The DB9 connection cable 3.5 mm stereo jack can 

be assembled as shown in the figure below or purchased as an accessory (code PM001601).

 

 ELECTRICAL CONNECTIONS 

WARNING

 

BEFORE CARRYING OUT ANY INSTRUMENT CONNECTIONS, MAKE SURE THAT YOU DISCONNECT ALL THE 

CIRCUITS SUBJECT TO A DANGEROUS VOLTAGE. TO CONNECT THE HIGH VOLTAGE INPUT USE ONLY THE 

PLUGS SUPPLIED WITH THE INSTRUMENT

 

Insertion of high voltage plugs 

The figure at the side shows the insertion points of the 

two 4mm banana plugs supplied with the instrument.

 

Polarity of the high voltage connection

 

In the case of DC measurement, the polarity 

is indifferent.
