ELECTRICAL CAL
Note.
The 4600 Series instruments incorporate a two point electrical calibration
sequence requiring both zero and span inputs for a calibration. It is not possible to adjust
either the zero or the span scale points independently.
Calibration
Proceed as described in Section 8.3 Calibration, but apply a signal input equivalent to
range zero (0.0 mV). Allow the instrument display to stabilize.
Advance to next parameter.
Calibration Range Zero %H2 IN CO2
Proceed as described in Section 8.3, but apply a signal input equivalent to %H2 IN AIR
range zero (0.00 mV) – see table below. Allow the instrument display to stabilize.
Advance to next parameter.
Calibration Range Span %H2 IN CO2
Apply a signal input equivalent to %H2 IN CO2 range span (10.0 mV) – see table below.
Allow the instrument display to stabilize.
Advance to next parameter.
Adjust Retransmission Zero
Set the milliammeter reading to 4 mA.
Note.
4 mA is retransmitted as 'zero' and is not affected by the retransmission type
selected in Section 10.1.3.
Adjust Retransmission Span
Set the milliammeter reading to 20 mA.
Note.
20 mA is retransmitted as 'span' and is not affected by the retransmission type
selected in Section 10.1.3.
