OPERATION
On / Off / Auto Power Off

Press the button to turn the meter on. The meter will shut off
automatically approximately 20 minutes after every power on.
The “auto power off” function can be disabled for recording or
operating over longer periods of time by pressing POWER and
HOLD buttons simultaneously before power on. An “n” will
appear in the middle of the screen at which time the HOLD button
can be released, and then the power button. The “auto power
off” mode has now been disabled.

Backlight Feature

Press the button and the backlight illuminates for
approximately 20 seconds then turns off automatically.

Measurement Modes

The meter can be set to measure pressure in the following
modes: bar, mmHg, ozin2, kgcm2, psi, inH20, kPa, ftH20, inHg,
cmH20 and mbar. Each press of the UNIT button will cycle
the meter through each of the measurement modes. An
arrow at the bottom of the LCD will indicate the mode
selected. The meter will default to the mode last selected
before meter was turned off.

Clearing Display to Zero

To clear the display to zero disconnect from all pressure and
press the HOLD button for 3 seconds. “o o o o” will appear
on the LCD and the meter value will be cleared to zero.

Hold Mode

Pressing the HOLD button once will “freeze” the measure­ment reading. “HOLD” will appear at the upper left of the LCD
indicating the meter is in the hold mode. Press the HOLD
button again to return the meter to pressure measurement
mode.

Differential Mode

Differential pressure is the measurement of the difference
between two pressures.

EXAMPLE: Use differential pressure sensor to measure
gauge pressure by leaving one process connection open
at atmosphere and connecting the second sensor port to
your system.

Press the DIF button, “DIF” appears at the top of the LCD.
The display indicates the relative zero – only the amount
of pressure change will be indicated. Press DIF button
again and the meter returns to normal pressure mea­surement mode.

Recording

1. Turn the meter on and press the HOLD button for 3
seconds. “o o o o” will appear on the display and the
pressure reading will be cleared to zero.

2. Press the REC button to begin recording a reading.
“REC” will appear in the lower left of the LCD, the
timer will begin counting up and the pressure value
will display.

3. To turn the record feature off press and hold the REC
button for 3 seconds.

NOTE: Only the REC, power and backlight buttons will
be operable in the Record mode.

Minimum/Maximum Readings

While in the recording mode the minimum and maximum
readings can be recalled.

1. Press the REC button and “MAX” will display in the
lower left of the LCD. The display will show the
maximum pressure value recorded and the time of
recording.

2. Pressing the REC button again displays the “MIN”
icon on the screen and the time and value of the
minimum pressure recording.

3. Another press of the REC button returns the display to
the current timer and pressure readings.

Error Messages Displayed

“Err.1” - Pressure value exceeds maximum range
“Err.2” - Pressure value is less than minimum range
“Err.3” - When operating in DIF mode, differential pressure value

is larger than maximum range

“Err.4” - Tubing was left connected while setting zero (try reset-

ting zero), if this does not clear the error the sensor or
meter is damaged.

“E10L” or “E2UL” (when operating RS232) - pressure source is

less or over range

ALL OPERATIONAL DIFFICULTIES

If this unit does not function properly for any reason, replace the
battery with a new high-quality battery (see “Battery Replace­ment” section). Low battery power can occasionally cause any
number of “apparent” operational difficulties. Replacing the
battery with a new fresh battery will solve most difficulties.

BATTERY REPLACEMENT

Erratic readings, a faint display, no display, flashing display or
“BAT” appearing on the display are all indicators that the battery
must be replaced. To replace the battery remove the tubing from
the unit. Lay the unit face down on a clean, flat surface. Remove
the screw from the battery cover and slide the cover off in the
direction indicated. Replace the exhausted battery with a new 9
volt alkaline battery. Replace the battery cover and screw into
place. Replacement battery Cat. No. 1112.
