6.2 Zero Point Adjustment
Adjust the zero point after operating preparation is
completed.
IMPORTANT
Do not turn off the power to the transmitter
immediately after a zero adjustment. Powering off
within 30 seconds after a zero adjustment will return
the adjustment back to the previous settings.
Using the Transmitter Zero-adjustment
Screw
Use a slotted screwdriver to turn the zero-adjustment
screw. Turn the screw clockwise to increase the output or
counterclockwise to decrease the output. The zero point
adjustment can be made with a resolution of 0.01% of
the setting range. Since the degree of zero adjustments
varies with the screw turning speed, turn the screw slowly
for fi ne adjustment and quickly for coarse adjustment.
