58 IM/AX4PH Rev. P
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 frames is
prevented and the display reverts to the top of the 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.
Single input analyzers only – see page 61.
Operating Page – see Section 2.3, page 6.
Calibrate Input for Sensor A ?
If calibration is required select
Yes otherwise select No.
Note. To abort calibration, press the key again at any time before calibration is
complete – see next page.
Millivolt Zero
Set the millivolt source to –1000 mV.
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 +1000 mV.
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
The display advances automatically to the next step once a stable and valid value is
recorded.
