1.4 OPERATOR CONTROLS

All operator controls are located on the front panel.
• The Zero Control is a single-turn potentiometer used to set
the display to "000" when no differential pressure is present at
the inputs.
• The Power Control is a double-action pushbutton switch that
controls the AC line and battery power. Power is "ON" when
the switch is pushed in. Power is "OFF" when the switch is
depressed again and returns to the out position.
• The Hold Control is a double-action pushbutton switch. The
pressure reading freezes at the moment the switch is pushed
to the "in" position. Depressing the switch a second time
releases the hold.
• The Unit Selection Controls are four pushbutton switches
used to select the unit of measurement displayed. They are
interlocked so that only one can be in the "in" position at a time
ensuring that only one unit of measurement can be selected
for display.

1.5. CONNECTIONS

Connections are located on the front and back panels.
• Pressure Input Connections are made to the HI and LO
pressure ports located on the front panel. The ports are
designed to accommodate ¼" ID flexible vinyl tubing (supplied

the ⅛" miniature banana jacks located on the front panel.

• Analog Output Terminals are the ⅛" binding posts located
on the back panel. They accept ⅛" miniature banana plugs, tip
jacks, or wire leads to provide output for a remote recording or
monitoring device (not included).
