4.6.5 Erasing stored measurement datasets

You can erase the stored measurement datasets altogether if you no
longer need them.
Erasing all measurement datasets is done in the menu, Configuration /
System / Measured value memory / Delete.
Erasing individual datasets is not possible. If all memory locations are
occupied, however, it is possible to overwrite the oldest dataset at a
time. A security prompt appears before a dataset is overwritten.

Transmitting data (RS 232 interface)

Via the RS 232 interface, you can transmit data to a PC or an external
printer.

4.7.1 Connecting a PC/external printer

Connect the interface to the devices via the AK540/B (PC) or AK540/S
(external printer) cable.
The RS232 interface is not galvanically isolated.
When connecting an earthed PC/printer, measurements cannot be per-
formed in earthed media as incorrect values would result.
Set up the following transmission data on the PC/printer:
Baud rate can be selected from: 1200, 2400, 4800, 9600,
19200
The baud rate must agree with the baud rate set on
the PC/printer.
Handshake RTS/CTS
PC only:
Parity none
Data bits 8
Stop bits 1s
