4.8.3 PC/external printer (RS232 interface)

You can transmit data to a PC or an external printer via the
RS232 interface.
Connect the interface to the instrument via the AK340/B ca-
ble (PC) or AK325/S cable (external printer).
The data output switches automatically to RS232.
Note
The RS232 interface is not galvanically isolated.
If it is connected to an earthed PC/printer, measurements
cannot be made in earthed media as this would give incor-
rect results!
Set up the following transmission data on the PC/printer:
