First, manually set the display to zero (no pressure applied to the connector ), refer to the 1.

manual zero procedure.

Turn the meter off.2.

Press 3. � &

simultaneously, “CA” appears on the display, (See Fig. 9 ) the meter enters

to the calibration mode, make sure the units setting on “PSI” to start positive (+) pressure

calibration.

The meter has defaulted as 1.6 psi calibration point, the adjustable pressure range is from 4.

1.5 to 1.7.

If calibration pressure source is not 1.6 psi, increase by pressing

key, or decrease by

pressing � key to set calibration point as required.

Save the calibration point by pressing 5.

key, “SA” and small “CA” appears on the

display in 2 seconds (See Fig. 10). The meter auto-skips to the negative pressure (-) point for

next calibration mode.

Follow the same procedure as step 4 for the negative pressure calibration point.6.

The LCD now displays” -1.600 “ and small”CA” (See Fig.11 ). Perform the necessary

calibration ﬁgure. Refer to your pressure standard if needed.

Again save the calibration point by pressing 7.

key, “SA” and “CA” appears in 2 seconds

and then press

;”End”and “CA” appear in another 2 seconds. The meter turns back to

the normal mode (See Fig. 12 ).

If you can’t save by pressing

key, i.e. no “SA” appeared, please check the followings:

 •thecalibrationpressuresourceisbetween1.5and1.7.or

 •ifyouenteredtherightpositivepressure(+)ornegativepressure(-).

If you want to skip positive (+) calibration when in the calibration mode, press

key to

skip to negative (-) calibration point.

Calibration point reference

MANUAL ZERO SETTING

When you set the display to zero( no pressure applied to the connector), press the

key

for 2 seconds. The meter should display “- 0 .000” from right to left (See Fig.13). Then, the LCD

display shows normal mode.

TROUBLESHOOTING

Cannot Power on.

Check the battery connections. Replace the battery or attach Optional AC adaptor.

Low BAT indication.

Replace the battery when LCD displays BAT.
