xxx = arbitrary number assigned by software
or
key
Adjust actuator output voltage using down key until value on
DVM ceases to change, then press up key until value on DVM
moves up one digit

Calibrate Span
(100%)
FUNCTION
Upper Display

SPAN
xxx = arbitrary number assigned by software
or
key
Adjust actuator output voltage using
key until value on DVM
ceases to change, then press
down key until value on DVM
moves down one digit
FUNCTION
Calibration for zero and span output values are now stored.
Slidewire Emulation Output Calibration is complete. Read meter
connected to actuator output.
Calibrate Position Sensor
ATTENTION
The Position Sensor is factory calibrated. Under normal operation it does not require
calibration.
Sensor calibration may be necessary due to any of the following conditions:
•
The sensor output is incorrect,
•
The position sensor in the actuator has been replaced,
•
The position sensor adjustment has been disturbed.
When the position sensor has been replaced (or serviced), you should perform a calibration of the position
sensor circuit and then store it as the motor factory calibration. Please note that performing this procedure
will destroy any previously stored motor factory calibration values. Table 29 outlines the steps to perform a
calibration to the position sensor circuit.
