Elma, Beha and TES are identical, only the packing is different!
Multimeter capable of measuring temperature, frequency and capacity as well.

The communication is specific: you send a space without CR, LF and the meter responds with 5 bytes.
Baud rate 9600, no parity, 1 stop, 8 data bits.
Older versions of the device has a button labeled »COMM«. You have to activate this, or the device will not open for communication with the pc.
Newer versions do not have this button, instead RTS must be set low in the serial communication.
December 1998 elma left production. New types are likely to show up.

Elma A/S has many other device of interest in physics.
E.g. on Frederikssund Gymnasium we have an excellent sound measurer, that also works as a microphone.

Elma 2732 has the same functions as elma 2730 + a datalog of 4048 bytes.
The reading takes some time, partly you need to read the format of the log, partly you have to read 8096 bytes.
The meter can remember 5 changes to the measuring area. When the log is full, or when you changed the measuring area more than 5 times, the displays blinks »com«. The meter does not have a clock built-in, so changing the time per measuring effects the already logged data as well.
