Calibration 11
NOTES:
1. If readings are not stable or are not within ±20% of zero, the zero correction can’t be entered.
2. If readings are not stable or are not within ±5% of 100%, the span correction cannot be entered.
3. For ease of calibration, do the Linearity/Hysteresis calibration , prior to doing ZERO/SPAN of next range.
3.4 Linearity and Hysteresis Calibration
Install the Condec Calibration Module (PN 60109) and select the LYN/HYS position of the rotary switch on the
module. This places the UPC5100/UPC5110 into its linearization/hysteresis calibration mode. The display is
shown in Figure 3-3 below.
NOTE: The zero/span calibration needs to be performed prior to linearity and hysteresis calibration.
Figure 3-3. Linearity and Hysteresis Calibration
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, vent
unit and repeat steps.
2. Perform the action as indicated when the readings are stable, 1 to 2 minutes. If it is taking longer, check
system for leaks. If no leaks are found, the CPU or transducer may be defective.
