OPERATING INSTRUCTIONS
POWER
1. Press to power the manometer ON or OFF.
When turned ON, the manometer will perform a
short self-test, then defaults to the setting used
during the last operation.
ZERO ADJUST AND OFFSET
1.Beforeuseandwithoutttingsattachedtothe
meter, press the HOLD button for longer than
two seconds to zero the meter. The meter will
reset, displaying “0000” from right to left. Then
the display shows 0.000.
2. If it is desired to offset the meter and display,
press the DIF button while taking a measurement. Subsequent readings will be the difference between the current measurement and
the measurement that was on the display when
the DIF button was pressed.
3. Press the REC button to display the minimum
(MIN) reading with the relative time.
4. Press the REC button to display the average
value (AVG) reading with the relative time.
5. Press the REC button again to continue record-
ing MAX/MIN/AVG measurements.
6. To exit the MAX/MIN/AVG mode and return to
normal operation, press the REC button for at
least three seconds.
BACKLIGHT DISPLAY
Press the button to turn the display backlight
ON. It will remain ON for forty seconds.
DATA HOLD
1. Press the HOLD button momentarily to freeze
the displayed reading. The HOLD icon will appear in th upper left corner of the display. If the
pressure value is over the range an error code
will display. Press the HOLD button again to
return to normal operation.
RECORD
The MAX/MIN mode allows the user to view only
the highest (MAX), lowest (MIN), or average
(AVG) readings with relative time stamp.
1. Press the REC button once. REC will appear
on the display. All other functions are locked
out except for power and backlight. The relative time clock also appears in the secondary
display and starts counting.
AUTOMATIC SHUTDOWN
The manometer will automatically shutdown after
twenty minutes to conserve battery life. To disable
Auto Shutdown, hold down the HOLD button and
press the to power ON the manometer. An
“n” will appear in the display indicating that Auto
Shutdown is disabled. The manometer will return to
normal operation when it is powered OFF.
ERROR CODES
An error message will display if the manometer
fails an internal diagnostic test. An error message
freezes all function buttons.
1. Err.1: Pressure value is over the range.
2. Err.2: Pressure value is under the range.
3. Err.3: DIF function, the differential pressure
value is over range.
4. Err.4: DIF function, the differential pressure
value is under range.
2. Press the REC button again and MAX appears
on the display. The display now shows the
maximum pressure and relative time that it was
recorded.
