Figure 3-3. Linearity and Hysteresis Calibration
Starting with the instrument's lowest pressure range, sequentially perform the thirteen steps described in
Table 3-2, for each pressure range being calibrated. Perform the following for each step:
1. Adjust input pressure to the appropriate value without overshooting the setting. If value is overshot by
more than 1%, vent unit and repeat steps.
2. Perform the action as indicated when the readings are stable. Should not take longer than 15 minutes. If
it takes longer, check system for leaks. If no leaks are found, the CPU or transducer may be defective.
When step no. 11 is reached, the display changes so that the left most status symbol is
H
. This remains for step 12
and down to approximately 0.00 PSI.
NOTES:
1. If reading is in motion or correction required is not within ±0.8% of Full-Scale, no entry is made.
2. If entry is valid, the display momentarily indicates the correction value (in percent) and the memory location
at which it is stored.
3. If 100% ±0.05% is not obtained, repeat the Zero/Span calibration sequence.
4. Absolute only unit: Maximum PSIA test standard display reading of 0.05 PSIA.
