HMP260 SERIES

Appendix 1: Serial commands HMP260-U017en-1.5

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

CT <cr>

T : 0.80 Ref1 ? 0.0 <cr>

Press any key when ready ...

T : 75.50 Ref2 ? <cr>

If the stabilization of the sensor to the temperature of the calibrator or the reference

needs to be monitored, the measurement output can be repeated by giving 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>

L Outputting linear correction coefficients

L <cr>

With the help of command L the user can check how the transmitter has been

adjusted after it has been calibrated at the factory.
