necessary.

Calibration Adjustment

Calibration adjustment is done electronically by internal software with the Product case

closed. All calibration commands and adjustments are done with the keypad.

Eight calibration points are used in the adjustment. They go from full scale to zero at

pressures that equal 100 %, 87.5 %, 75 %, 62.5 %, 50 %, 37.5 %, 25 %, 12.5 %, and 0 %

of full scale plus vacuum.

Note

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.
