Element

1. Set pressure at minimum value (see range on
element nameplate).
2. If pointer does not read correctly, use zero
adjustment to reposition pointer.
3. Set pressure at maximum value. If pointer does
not read correctly, use multiplication adjustment
to reposition pointer about halfway toward
correct reading.
4. Repeat steps 1, 2 and 3 until both readings of
pointer are correct.
5. Set pressure at mid-range. If pointer is not at
midscale, adjust length of link to move pointer
about 5 times amount of error in direction of
error. (Subsequent renement in settings
of adjustments will bring instrument into
calibration).
6. Repeat steps 1 through 5 until all readings of
pointer are correct.

mounting screws.
3. Unscrew tubing connection and remove
assembly.
4. After replacing element assembly, check
