4. Check the calibration is correct:
• Select the applicable Voltage (10V) or Current (24V)
(measure) function (See Section 5.7).

PROCEDURES: PRESSURE INDICATOR 5.9
Do the procedure as follows:
1. Connect the instrument to the pressure standard.
2. Let the equipment get to a stable temperature (minimum: 60
minutes since the last power on).
3. Use the calibration menu (See Section 5.4) to do a two-point
calibration.
• Zero and +FS for gauge sensors.
4. Check the calibration is correct:
• Select the applicable pressure function.
• Apply the following pressure values.
0, 20, 40, 60, 80, 100, 80, 60, 40, 20 (%FS).
• Apply the following pressure values.
-200, -400, -600, -800, -600, -400, -200, 0 mbar.
• Check the error is within limits
From the datasheet use the values in the Accuracy column.
