Factory Settings Access Code
Enter the required code number, between 0000 and 19999, to gain access to the factory
settings. If an incorrect value is entered, access to subsequent parameters is prevented
and the display reverts to the top of the
Factory Settings Page
.
Calibrate Sensor A
Note.
The values in the display lines for sensor calibration are shown only as
examples – the actual values obtained will differ.
Sensor B calibration (dual input analyzers only) is identical to Sensor A
calibration.
See page 53.

– see Section 2.3.
Millivolt Zero
Set the millivolt source to –1000mV.
The display advances automatically to the next step once a stable and valid value is
recorded.
Note.
The upper 6-segment display shows the measured input voltage. Once the
signal is within range the lower 6-segment display shows the same value and
Calib
is
displayed to indicate that calibration is in progress.
Millivolt Span
Set the millivolt source to +1000mV
The display advances automatically to the next step once a stable and valid value is
recorded.
Temperature Zero (100R)
Set the temperature simulator to 100
Ω
The display advances automatically to the next step once a stable and valid value is
recorded.
Temperature Span (150R)
Set the temperature simulator to 150
Ω
The display advances automatically to the next step once a stable and valid value is
recorded.
