Before use and without fittings attached to the meter, press the HOLD button
for more than 2 seconds to zero the meter. The meter will reset and display
"000" from right to left. 0 .000 will be display.
If it is desired to offset the meter and display, press the DIF button while
taking a measurement subsequent reading will be the difference between the
current measurement and the measurement that was on the display when the
DIF button was pressed.
3. Data Hold
Press the HOLD button momentarily to freeze the displayed reading the
HOLD icon will appear on the upper left-hand side of the display. press the

(MIN) or anerage (AVG) readings with relative time stamp.
1 . Press the REe button once and REe appears on the display (All other
Functions are locked out except for Power & Backlight) . The relative time
clock also appears in the secondary display and starts counting .
2 . Press the REe button again and MAX appears on the display. The
Display is now showing the maximum pressure and relative time it was
recorded .

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 recording MINIMAXI AVG
measu rements.
6. To exit the MINIMAXI AVG mode, press the REC button for 3 seconds to

Error Codes
An error message will appear on the display if the meter fails an internal
diagnostic test.
1. Err. 1: Pressure value is over the range.
2. Err. 2: Pressure value is below the range.
3. Err. 3: DIF function, the differential pressure value is over range .
4. Err. 4: DIF function, the differential pressure value is below range.
BaHery Replacement
When the battery power falls low, "BAT" will appear on the LCD . Replace
the 9V battery.
