4.8 Transmitting data (to a PC or printer)
The meter has two interfaces:
z RS232 interface (serial port)
z USB interface (device)
Via both interfaces, you can transmit data to a PC and update the meter
software.
The RS232 interface enables to transmit data to an external serial
printer.
Note
The relevant interface cable has to be connected if you want to
download data to an interface (USB or RS232).
It is not possible to download data to both interfaces (USB and RS232)
at the same time. After connecting a meter to the USB socket the
RS232 interface is inactive. The RS232 interface is active if no meter is
connected to the USB interface.
CAUTION
The RS232 and USB interfaces are not galvanically separated.
When connecting an earthed PC/printer, measurements cannot be
performed in earthed media as incorrect values would result.
