5-1-3. Other Calibration and Adjustment
(A) ON/OFF Controller
Before starting adjustment, check zero deviation as follows:
(a) Set the setpoint at 50 %.
(b) Remove the travel link (PV) of the indicating mechanism side and insert the
adjustment pin.
(c) Check that the PV pointer and the SP pointer are accurately aligned together. If there
is any shift, correct is by means of the SP pointer adjustment pin.
(d) Remove the adjustment pin and connect the travel link (PV).

Adjustment
(1) Turn the setting dial full counterclockwise and align it with the white line at the end of the
INC. MEAS. INC. OUT side. Adjust the deviation so that the output becomes 59.1±0.8
kPa {443±6 mmHg} and read the deviation with the pointers on the scale.
(2) Turn the setting dial full counterclockwise and align it with the yellow line at the end of
the INC. MEAS. DEC. OUT side. Make adjustment in a similar manner as in the case of (1).
(3) Adjust the length of the deviation link so that the deviations read in (1) and (2) become
identical values but in reverse directions. The length becomes shorter as you turn upward
the deviation link adjustment screw. If the deviations are in the same direction and the
reading of the red pointer is higher than that of the green pointer, lengthen the link; if the
reading of the green pointer is higher, shorten the link.
(4) Set the deviation at 0 (zero) and align the setting dial with the white line. Adjust the
flapper adjustment screw so that the output is stabilized at a point within a range of 10 to
130 kPa {0.1 to 1.3 kgf/cm
2
}.
(5) Align the setting dial with the yellow line, Adjust the length of the deviation link so that
the output is stabilized at a point within a range of 10 to 130 kPa {0.1 to 1.3 kgf/cm
2
}.
(6) Repeat the procedure of (4) and (5) so that the output is stabilized at a point within a
range of 10 to 130 kPa {0.1 to 1.3 kgf/cm
2
} regardless of whether the dial is aligned with
the white line or with the yellow line.
