1. Select High/Low Pressure Range in source mode.
◆
The calibrator must be vented or in standby mode.
◆
The calibrator will automatically vent when switching ranges.
2. Connection: Complete the pneumatic connection as shown in
Figure 3-3 or Figure 3-4.

◆
The maximum negative pressure is -13.5 psi (-0.95 bar).
But this is dependent on the local atmospheric pressure.
◆
The value cannot exceed the control range of the CONTROL SETUP,
or the calibrator will prompt the user to reset the limits.
