Basic Operation

Meter Power

The HD700 uses a 9V battery for power. If the meter does not switch on when the POWER

button is pressed or if the display shows BAT, replace the battery.

When the POWER buttons is pressed, the meter performs a short self-test and reverts to

the settings in place when the meter was last turned off.

Automatic Power-off Feature

In order to conserve battery life, the meter has an automatic power off feature (after 20

minutes). To defeat this feature, press and hold the HOLD button while turning the meter

on. Release the HOLD button when ‘n’ appears on the display. The meter will now remain

on until the user turns it off or until the battery weakens. Note that the Auto Power OFF

feature will be reactivated the next time the meter is turned off and then on.

Unit of Measure

Press the UNIT button to select the unit of measure. This meter offers eleven (11) units of

measure as listed below.

Fittings Connection

Connect tubing to the P1, P2 (or both) input port(s). If both inputs are used (differential

mode), the meter displays a positive pressure reading if the P1 pressure is greater than P2

and a negative reading if P2 is greater than P1.

Zero Adjust and Offset function

To ZERO the meter: Before use and without fittings attached to the meter, press and hold

the HOLD button for 3 seconds or until the display shows all zeroes.

To OFFSET meter readings: Press the DIF button while taking a measurement.

Subsequent readings will represent the difference between the current measurement and

the measurement that was on the display when the DIF button was pressed.
