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.

4.7.1

Connecting a PC

Connect the interface to the devices via the AK540/B (PC) cable.

The RS232 interface is not galvanically isolated.
When connecting an earthed PC, measurements cannot be performed
in earthed media as incorrect values would result.

Set up the following transmission data on the PC:

Baud rate

can be selected from: 1200, 2400, 4800, 9600,
19200
The baud rate must agree with the baud rate set on
the PC.
