1–2 Calibrating Your Module
Publication 1771Ć6.5.116 - July 1996
If a calibration check of your module becomes necessary:
1. Verify that the module is in voltage mode. In single-ended mode,
apply voltages to channels 1 through 16.
2. Send a configuration block transfer write to the module that
replicates the specific application. (This forces the module to do
an internal calibration.)
3. Apply –10V, –5V, –2.5V 0V, 1V, 2.5V, 5V, and 10V to the
module. In differential, apply voltages to channels 1 through 8
Verify that the values returned are within 0.1% of bipolar full
scale.
Range Scaling Accuracy (V/mA)
0 to 5V 0, 5000
1 to 5V 1000, 5000 +0.010V
-5 to +5V -5000, 5000
-10 to +10V -9999, 9999 +0.020V
4 to 20mA 400, 2000
0 to 20mA 0, 2000 +0.04mA
-20 to +20mA -2000, 2000
Range Error (counts) (no scaling)
0 to 5V +4
1 to 5V +4
-5 to +5V +8
-10 to +10V +8
4 to 20mA +4
0 to 20mA +4
-20 to +20mA +4
4. If values are within tolerance, no calibration is necessary. If not,
perform calibration below.
