Calibration Manual

Calibration Adjustment

Calibration adjustment is done electronically by internal software with the Product case
closed. The recommended adjustment procedure is a 2-point adjust that adjusts a low and
high point. This adjustment can be applied to any of the 700 family of gauges. It is the
only adjustment that may used with a 700RG ranges.
This is an ambient temperature calibration, and must be done at an ambient
temperature of 23 °C ± 3 °C (72 °F ± 5 °F). Calibration out of this
temperature range voids the temperature compensation software in the
Product.

Test Equipment

For verification and calibration adjustment, pressure and/or vacuum standards that can
make and show pressures from vacuum to the full-scale range of the UUT are necessary.
A TUR standard of 4:1 or better is necessary to keep the Product at its specified accuracy.

Connections

The Product uses a ¼ inch NPT male connection in the pressure input port. Different
adapters can be necessary to connect to the pressure standard. Always make sure the
hose, tubing, and fittings. Have a rated working pressure at or above the pressure of the
unit. It is also important that there be no leaks when you calibrate the Product. Use Teflon
tape where necessary.
