Operating Instructions
Note: This meter is fitted with two 4.8mm lugs. Before you connect the
meter to a pressure source, carefully check the security of all fittings.
Auto Power-Off (Sleep function)
1. This instrument shuts off automatically after
approx. 20 minutes of inactivity.
2. For operating over longer periods of time,
you can disable the sleep mode by pressing
and simultaneously before
powering on.
3. An “n” will appear in the middle of the
screen at which time you can release
the button. (See Fig. A)
4. The disabled sleep mode will be invalid
after power off.
Mode Options
There are six function keys for mode selection as
well as measurement operation.
For your convenience, the meter defaults to the
setting used in the last operation.
The following lists the operation for each function key.
Turns instrument on (Default setting) and off.

Press to enter recording. A counter will
begin and REC will show up on screen
indicating you have begun recording.
Press the button again and the
unit will cycle through the MAX (Fig. C)
and MIN (Fig. D) measurements
captured during the recording mode.
Press and hold for 3 seconds to
turn off the record function and to return
to normal mode.
Press momentarily to freeze the current
pressure reading. (See Fig. E)
Press momentarily, DIF appears on top
of the LCD and the display indicates the
relative zero (Relative zero causes the
value of the display to show as “0.0”);
only the amount of pressure change will
be indicated. Press momentarily again
and the unit returns to the normal mode
of pressure differential (See Fig. F).
Note: Differential Pressure is a measure of the difference between two
pressures, i.e. use differential pressure sensor to measure gauge pressure
by leaving one process connection open to atmosphere and connecting
the second sensor port to your system. continued ...

Press momentarily and the unit will cycle
through “bar”, “mmHg”, ”ozin2”, ”kgcm2”,
”psi”, ”inH2O”, ”kPa”, ”ftH2O”, ”inHg”,
”cmH2O”, ”mbar” which is indicated on
the bottom of the display (Fig. G & H).
Press momentarily and the backlight
illuminates for approx. 30 seconds then turns
off automatically. Or press momentarily to
decrease the time when calibration is being
performed.
Calibration Mode
1. Manually set the display to zero (no pressure
applied to the connector), refer to Manual Zero
procedure.
2. Turn the meter off.
3. Press & simultaneously, ”CA”
appears on the display (See Fig. I ). When the
meter is in calibration mode, make sure the
arrow mark “ “ is positioned under the “psi”
pressure unit to start positive (+) pressure
calibration.
4. The meter defaults to a 80 psi calibration point,
the adjustable pressure range is from 78.0 to
82.0 psi. If the calibration pressure source is
not at 80 psi, increase the figure by
pressing button or decrease the figure by
pressing button, to set calibration point
as required.
5. Save the calibration point by pressing
button, “SA” and small “CA” appears
on the display (See Fig. J).

The meter auto-skips to the negative pressure
(-) point for the next calibration mode.
6. Follow the same procedure as outlined in
Step 4 for the negative pressure calibration
point by pressing button, the LCD
now displays ”-80.0“ and small ”CA”
(See Fig. K ). To set the necessary calibration
gure refer to your pressure standard if needed.
7. Again save the calibration point by pressing
button, “SA” and “CA” appears in 2
seconds and then “End” and “CA” appears
in another 2 seconds, the meter returns
to normal mode (See Fig. L ).
Note: If you cannot save by pressing button, i.e. no “SA” appeared,
please check: (a) that the calibration pressure source is between 75.0 and
85.0, or check (b) if you entered the right positive pressure (+) or negative
(-) pressure.
If you want to skip positive (+) calibration procedure when entered into
Calibration mode, press button to skip to negative (-) calibration
point. Above calibration is an example for Model R3100, i.e. the pres-
sure range is from 0 to +100psi (positive pressure ) or from 0 to -100 psi
(negative pressure).

Manual Zero Setting
When you set the display to zero (no pressure
applied to the connector), press button
for 2 seconds, the meter displays “0.0.0.0”
from right to left (See Fig.M) and then
delete each “0” from left back to right, the
LCD display shows a normal mode (See Fig.N).
Troubleshooting
• Power on but no display. Checkthatthebattery
isproperlyinstalledensuringthatcontactwith
terminalsandpolarityarecorrect,replacewitha
newbatteryorattachoptionalACadapter.
•BAT indication. Replace with a new battery when
LCD displays BAT at the middle bottom of screen.
•No display. Make sure that the battery is not
drained, if the display disappears, verify if
sleep mode is active. Refer to the Disable
sleep mode function for long term measurement.
Check that the tubing is tightly connected to
the meter.
•Err.1. If the pressure value exceeds the range
maximum, “Err.1“ appears on the display (See
Fig. O), it is recommended to use a meter with a
higher range, otherwise, the meter will be
damaged in use.
•Err.2. If the pressure value is less than the range
minimum, “Err.2“ appears on the display (See
Fig. P), it is recommended to use a meter with
a lower range to ensure measurement accuracy.
• Err.3. While operating the DIF function, if
the differential pressure value is larger than
maximum display digit, Err.3 appears on the
display (See Fig.Q ).

• Err.4. When you set zero, ensure you
have disconnected the tubing and that no
pressure is applied to the connector. If Err.4
appears on the display, it means the sensor
or the meter are damaged (See Fig.R). Return
the unit to point of purchase for repair.
Err.4 will also appear when the tube or the
hose is connected during setting zero mode.
Battery Replacement
Replace the battery when
• The BAT icon appears on the left side of the display screen
• The meter will not power on
• Use of the backlight causes the BAT icon to appear
Even if the battery was recently replaced, check its voltage level if you
get no response from your instrument.
To replace the battery:
1. Remove the tubing of the instrument.
2. Lay the instrument face-down on a clean, at surface.
3. Remove the battery with a screwdriver and observe indicated polarity
and close the cover after replacing with a new battery.
Note: Remove battery from instrument if you do not plan to use for a
month or more.
Do not leave battery in instrument.
