Item Description

Supply metering valve. Use the supply metering valve to regulate the incoming air supply.
See the “Typical Connections” section for more.

Isolation valve. This valve isolates the right-most port and pressure sensor from the
Vent/Fine adjust, pump, and Supply Metering Valve.

Pump Pressure/Vacuum. In the + position, the pump operates from 0 psi to 300 psi. In
the - position, the pump runs in vacuum mode, which is 0 psi to -12 psi.

Fine adjust/vent. Use the small silver knob of this valve to bleed off the pressure in a
controlled manner. If left open, it will vent all pressure off safely. The outer-most knob
(black) is a vernier control that varies the volume which finely reduces or increases the
pressure.
 Power Adapter input.

24 V power for voltage transmitters. This jack only powered when in Voltage Measure
mode.
 Common Jack.

Input Jacks. Use the input jacks for volts and milliamp functions. See the “Measure and
Source Current (4… 20 mA)” and “Measure Voltage” sections. Also used for switch test.
 External pressure module connection. See the “External Modules” section.
