Figure 11-7: Low calibration value for voltage
Click 100% Cal Point. The Enter 100% Calibration Value dialog box displays with the
target high value automatically calculated. For example, the value is 100.000 for the range
value of 100.
Adjust the calibrator to apply the high value (100%) of the signal range. For example, if
the signal range of the external device is 1-5 Vdc, apply 5 Vdc.
Observe the value in the Current Reading field. When the value stabilizes, click OK.
If the high range value in the field is accepted, click OK.
Click 50% Cal Point. The Enter 50% Calibration Value dialog box displays with the target
mid value automatically calculated. For example, the value is 50.000 for the range value of
100.
Adjust the calibrator to apply the 50% value of the external device signal range. For
example, if the signal range of the external device is 1-5 Vdc, apply 3 Vdc.
Observe the value in the Current Reading field. When the value stabilizes, click OK.
When the Calibration Complete message displays, click OK.
Verify that the Entry values are updated, and that the Current Value field displays the
calibrated value based on the defined range.
Figure 11-8: Calibrated AI example (voltage mode)
Remain in the calibration screen and keep the calibrator connected to the AI. To verify the calibration,
proceed to section 11.5.5 Verify analog input calibration.
11.5.4 Analog input calibration (current mode)
This procedure describes a three (3) point calibration. Available target values for this option display in
the calibration window and become active in calibration order:
