In one-point offset correction, the Ref2 prompt is acknowledged with <cr>:
>CT <cr>

T : 75.50 Ref2 ? <cr>
If the stabilization of the sensor to the temperature of the calibrator or the ref-
erence needs to be monitored, the measurement output can be repeated by giv-
ing command c<cr> at Ref1 and Ref2:
>CT <cr>
T : 0.80 Ref1 ? c <cr>
T : 0.40 Ref1 ? 0.00 <cr>
Press any key when ready ...
T : 56.20 Ref2 ? 55.0 <cr>
ACAL Calibrating the analogue outputs
Disconnect the security lock jumper!
ACAL <cr>
Calibrates the outputs selected on channels 1 and 2. The output is measured
and the measured values (mA or V) entered as calibration coefficients.
For example, calibrating the outputs when 0...10 V signal has been selected on
both channels (set with AMODE command)
>ACAL <cr>
Ch1 U1 (V ) ? 0.123 <cr>
Ch1 U2 (V ) ? 9.98 <cr>
Ch2 U1 (V ) ? 0.120 <cr>
Ch2 U2 (V ) ? 9.98 <cr>
