7.2 Current Proportional Output Calibration
Introduction
Calibrate the controller so that the output provides the proper amount of
current over the desired range.
The controller can provide an output current range of from 0 to 21
milliamperes and can be calibrated at 4 mA for 0% of output and 20 mA
for 100% of output or any other values between 0 and 21 mA.
We recommend that the expected output load be connected for optimum
accuracy.
Equipment needed
You will need a standard shop type milliammeter, with whatever accuracy
is required, capable of measuring 0 to 20 milliamps.
Calibrator
connections
Refer to Figure 7-1 and wire the controller according to the procedure
given in Table 7-1.
Table 7-1 Set Up Wiring Procedure Current Proportional Output
Step Action
1
Tag and disconnect the field wiring, at the rear of the controller, from
terminals 20(+) and 21(–). See Figure 7-1.
2
Connect a Milliammeter across these terminals.
3
Connect a load resistor, equivalent to the process load, in series with
the milliammeter. See Figure 7-1.
4
Apply power and allow the controller to warm up 15 minutes before
you calibrate.
