Calibrate Output
10260S actuator can be one of three output types:
1. 0 mA to 20 mA, or 4 mA to 20 mA output
2. 0 Volts to 5 Volts, or 1 Volt to 5 Volts with 250 ohm range resistor
3. Slidewire emulation.
The output signal range is selected through the Current Out set up group using the keypad and local
display.
0/4-20 mAor 0/1-5 Volts Output
The 10260S Actuator comes already calibrated from the factory. If it becomes necessary to do a calibration
in the field, adjust the output using the procedure in Table 25. Refer to Figure 17 for a diagram to connect
a signal source to the actuator input and a DVM to measure actuator output signal.
This procedure provides the steps to calibrate the actuator for a 0/4 to 20mA output. If you are using
another output type, change the procedure accordingly. Please note that the actuator output is factory
calibrated for
only
the 4 – 20 mA output selection. Any other output selection will require you to perform
an output calibration.
ATTENTION
For an output calibration to be saved, you must complete the procedure. The calibration will
not be saved if you exit without completing the steps of the procedure.
To exit calibation mode, press DISPLAY or SETUP keys.
