•
Adjust actuator output to a value equal to 0% output as read
from the DVM.
NOTE: Typically for a 4 mA output, the display will show a value
of approximately 381. A lower limit value is imposed on the zero
output. If the value is 357 or lower, the actuator will not allow you
to calibrate the zero output. The value must be larger than 357
for a valid calibration.

FUNCTION Calibration for zero and span output values are now stored.
Output calibration is complete.
Slidewire Emulation
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 26. Refer to Figure 18 for a diagram to connect a
signal source to the actuator input and a DVM to measure actuator output signal.
ATTENTION
For a slidewire emulation 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 calibration mode, press DISPLAY or SETUP keys.
