Test of channel 0 of the analog/digital converter (with a
reference voltage at the signal input of the sensor con-
nector (→  20)).
If the signal input is open, the TPG 261 displays
a default value that may easily fluctuate be-
cause of the high sensitivity of the open meas-
urement circuit.
Test sequence
e.g.:
Ö Measuring signal in Volt.
