5.1.1 Voltage Measurement
Two methods are available for voltage measurement: single-
ended and differential measurement.
With the single-ended type the voltage to be measured is con-
nected between an analogue input (In+) and analogue ground
(AGND). Differential measurements are realized by using two
analogue inputs (In+ and In-). Measuring range is between 0
and ±10 V.
Note: With differential measurements both voltages have to be
within 10 V referred to AGND (Common-Mode-Range).
It is recommended to connect the In- to A
GND
with a high ohmic
resistance.
