Calibrate Pressure Span

3-68 Model 43i Trace Level-Enhanced Instruction Manual
The Calibrate Pressure Zero screen calibrates the pressure sensor at zero
pressure.
Note A vacuum pump must be connected to the pressure sensor before
performing the zero calibration.
In the Main Menu, choose Service > Pressure Calibration > Zero.

RANGE
The Calibrate Pressure Span screen allows the user to view and set the
pressure sensor calibration span point.
Note The plumbing going to the pressure sensor should be disconnected so
the sensor is reading ambient pressure before performing the span
calibration. The operator should use an independent barometer to measure
the ambient pressure and enter the value on this screen before
calibrating. ▲
