OPERATING SPECIFICATIONS

1. Working Pressure Limitations

a. Dynamic Pressure

The working pressure should be

limited to 60% of the dial range.

Max. 0.9x full scale.

b. Static Pressure

The working pressure, where no

sharp fluctuations occur, should be

limited to 90% of the dial range.

Max. 1x full scale.

c. Short term max. 1.5x full scale

(<10,000 psi).

* For every 18 °F (10 °C) shift in temperature from

which the gauge is calibrated, the user can

experience up to ±0.4% additional error.

** See page 51 for gauge fill options.
