7.3 2nd Current Output Calibration, Continued
Procedure
The procedure for calibrating the 2nd Current Output is listed in Table 7-
5. Make sure “LOCKOUT” in the Tuning Set Up group is set to “NONE.”
See Section 3 – Configuration.
Table 7-4 2nd Current Output Calibration Procedure
Step Description Press Action
1
Enter Calibration Mode
SET
UP
until you see
CUR OUT2
Lower Display
CALIB
Upper Display
2
Calibrate 0%
FUNC
L1/L2
You will see:
Lower Display
Upper Display
ZERO VALU
(a value)
or
until the desired 0% output (normally 4mA) is read
on the milliammeter. Use the values shown below
depending on the action of your controller.
*
When attempting to achieve 0 mA, always adjust the
output to about 0.5 mA, and slowly decrease until the
output just goes to zero. Further decrementing will not
change the output current (since the circuit cannot produce
negative current) but will affect the accuracy of the output
by creating a dead zone where no current flows.
3
Calibrate 100%
FUNC
L1/L2
This stores the 0%value and,
you will see:
Lower Display
Upper Display
ZERO VALU
(value)
or
until the desired 100% output (normally 20mA) is
read on the milliammeter. Use the values shown
below depending on the action of your controller.
4
Exit the Calibration
Mode
FUNC
L1/L2
The controller will store the span value.
or
