CompactPowerMonitor CPM

Analog output
The CompactPowerMonitor CPM has an analog voltage output (analog output) that emits a voltage value
analogous to the measured laser power. The analog signal is effected via the 4-pin device socket M8 (see
Fig. 5.1 on page 12). The output voltage amounts to a maximum of 10 V. The output voltage of 10 V is
scaled to the maximum output value of the connected device (see Tab. 9.3 on page 31). A suitable con-
nection cable is included in the scope of delivery.
The load resistance at the analog output should not be smaller than 100 kOhm.
An output voltage of 1 V
equals approx.

Output voltage and laser power
When power is supplied through the USB port, it is not necessary to hook up 24 V through Pin 1 and Pin 2.
