PROCEDURES: PRESSURE INDICATOR
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.
o
0, 20, 40, 60, 80, 100, 80, 60, 40, 20 (%FS).
•
Apply the following pressure values.
o
-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.
