HBM CMA Bedienungsanleitung Seite 19

between measurements with sensor 1 and measurements with sensor 2 is not
possible as both sensors are always measured together.
Important
Fit the supplied cover if you only use one input on the CMA5000/2.
The CMA charge amplifier is designed for direct voltage operation (18 ...
30 V ). The circuit is intended for operating with separated extra‐low voltage
DC
(SELV circuit).

Operating on a SELV circuit (separated extra‐low voltage)
Fig. 7.1 Pin assignment
The output signal is present at pin 5 and pin 6 (ground), and is electrically
isolated from the supply voltage and the control inputs. The RANGE 1/2,
MEASURE/RESET and TEDS control inputs, as well as the supply voltage, are
at the same potential (pin 1, supply voltage 0 V). It is not necessary to ground
the housing.
