Electrical Calibration
Select YES to access the electrical calibration sequence. Select NO to advance to
Adjust Retransmission Zero – see following page.
Microamp Zero
Set the current source to 0 µA and allow the instrument display to stabilize.
Microamp Span
Set the current source to +100 µA and allow the instrument display to stabilize.
Calibrate Temperature Zero
Set the temperature simulator resistance box to 1000Ω and allow the instrument
display to stabilise.
Calibrate Temperature Span
Set the temperature simulator resistance box to 1500Ω and allow the instrument
display to stabilise.
Adjust Retransmission Zero
Set the milliameter reading to 4.00mA.
Note. Retransmission signal span is calibrated using 20.00 mA. The correct
value transmitted depends on the range selected in the Set Up Outputs Page.
Adjust Retransmission Span
Set the milliameter reading to 20.00mA.
Note. Retransmission signal span is calibrated using 20.00 mA. The correct
value transmitted depends on the range selected in the Set Up Outputs Page.
