The drawing below shows a typical solid front, lower connec-
tion Duragauge with all of the parts designated by their stan-
dard names. The use of these names will facilitate the
ordering of parts and eliminate any misunderstanding in
describing gauge construction. When ordering parts – specify as much of the following data
as possible:
Size (Dial Diameter); Case Material (Stainless
Steel, Polypropylene, Aluminum or Phenol); Case Type (Open
Front or Solid Front); Ring Design (Slip, Internal Threaded,
External Threaded, Bayonet, Snap or Hinged); Connection
Location (Lower or Back); Connection Size ( 1 ⁄
4
˝ or 1 ⁄
2
˝);
Bourdon Tube/Socket (Material Indicated on Dial); Dial Range
(Specify type number if possible; otherwise, mention whether
parts are for Duragauge, General Service Gauge, Special
Application Gauge, Receiver Gauge or Test Gauge.)

1. Preliminary Gauge Calibration Setting –
(SOLID FRONT GAUGE SHOWN)
2. Calibration –
a. At zero pressure (or at full vacuum for compound
or vacuum gauges), assemble pointer to pinion
shaft in the horizontal position.
b. Apply pressure equal to full range and adjust the
slide in the segment slot until the pointer has
rotated 270° (vertical position).
c. Reduce pressure to zero and reset pointer, if nec-
essary, to horizontal position. If pointer adjust-
ment was required, repeat step (b) above.
d. Apply pressure equal to mid-scale and drive
pointer firmly onto pinion.
e. Recheck calibration at the lower and upper ends
of the scale.
3. Linearity Adjustment – Although the procedure out-
lined above should produce a correctly calibrated
gauge, linearity adjustment may be required. If the
pointer reads correctly at the bottom of the scale
and low at the top of the scale, rotate the movement
to increase the angle between the link and the seg-
ment. If the pointer reads high, rotate the movement
in the opposite direction.
1279 case used to
clearly illustrate the
gauge components.
Note: The socket, tube and tip assembly is furnished as one
integral unit. The movement is supplied complete.
