(5) Input a 100% input signal.
Apply 20mA for 4 to 20mA input or 50mA for 10
to 50mA input.
Control the zero adjustment so that the output
air pressure reaches a specified pressure.
For 100% output air pressure, see the data
plate or Table 5.2 “Output Signals.” (See Figure
5.3.)
To increase output air pressure, please turn
span adjustment clockwise. To decrease output
air pressure, please turn span adjustment
counterclockwise. (See Figure 5.3.)
For the model with reverse action (/RA), please
turn span adjustment counterclockwise to
increase output air pressure. To decrease
output pressure, please turn span adjustment
clockwise.
(6) Input a 0% input signal.
Confirm if 0% output air pressure reaches the
specified pressure. If not, make zero point
adjustment.
(7) Input a 100% input signal
Confirm if 100% output air pressure reaches
the specified pressure. If not, make span
adjustment.
(8) Repeat steps (6) and (7) two to three times to
adjust the zero point and span.
(9) After completing adjustments, change the input
signal to 0%, 25%, 50%, 75%, and 100% and
confirm if the specified output is reached at the
relevant input.
Confirm the accuracy with reference to the input
and output signal reference values given in
Table 5.5 “Input and Output Signals.”
