MANOMETER/PRESSURE/VACUUM INSTRUCTIONS
(Continued from previous page)
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 measure-
ment 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 dis-
play.
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 low-
er 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 resetting
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 di-
rection indicated. Replace the exhausted battery with a new 9 volt
alkaline battery. Replace the battery cover and screw into place.
