7 PROGRAMMING AND ELECTRICAL CALIBRATION...
Enter Input %
Set the percentage of the display span at which the breakpoint occurs: 1.0 to 100% in
0.1% increments. This is point A on Fig. 7.1.
Enter Output %
Set the percentage output at which the breakpoint occurs: 0.0 to 100% in 0.1% steps.
This is point B on Fig. 7.1.
Diagnostics
Select whether the current output diagnostics are required. See Appendix B.
Calibration Pulse Time
Set the frequency of the calibration pulse signal. Programmable frequency of 15, 30, 45
seconds, 1, 2, 3, 4, 5 minutes.
See Appendix B.
Calibration Fail Mark Time
Set the mark time period for the current output to be driven hard upscale. Programmable
period of 30 seconds, 1, 2, 3, 4, 5, ...,10 minutes.
See Appendix B.
No Retrans 2
Calibration Fail Space Time
Set the space time period for the current output to be driven to 0%. Programmable
period of 30 seconds, 1, 2, 3, 4, 5, ...,10 minutes.
See Appendix B.
Test Retransmission Output
The instrument automatically transmits a test signal of 0, 25, 50, 75 or 100% of the
retransmission range selected above. The % test signal selected is shown on the upper
display.
– for a selected range of 0 to 20 mA and 50% retransmission test signal, 10 mA
Example
is transmitted.
Select the required retransmission test signal.
