Command Summary
Data format
Every entry in the log contains a time stamp from the build-in real time clock. This clock may also be
used for starting the logging at a specific time.
The logged data consist of measured as well as computed results. The format for one log record is
Year,month,date,hour,minute,second, Ws, Wh, V, A, VA,
ϕ
, W
A typical record may look like this:
2011,01,18,10,24,13, 201.4, 0.1, 2.9, 0.69, 2.0, 0, 2.0
Comma is field separator. Decimal separator is dot/period/full stop. Leading white space may be in-
serted before numbers.
When the log is read by means of a terminal program, 255 lines will appear.

A
Reads collected data. All data are sent to the computer. While transmitting data the
communication is blocked for other messages. The time of transmission will vary
depending on the number of data transmitted, in some cases it may take
several seconds.

B
Command for selecting transmission rate. The transmission rate indicated as
baud-rate (bits/s) has to be the same rate for both the Instrument and the computer.
The pre-selected rate (Default baud-rate) is 1200 b/s.
The rate can be changed e.g. by using the command ‘b300’. If in doubt about the
actual baud-rate simply write ‘b’ and the actual baud-rate is displayed.
C
