Congratulations on your purchase of
the Manometer ! This instrument is
portable, battery operated pressure
measuring device.
The Manometer is ideal for HVAC/R
technicians measuring pressure
level ,Medical equipment ,Computer
peripherals , Pneumatic Controls.
The meter will display all LCD
segments when it is first turned on
for approx. 3 seconds. Though you
might see DATALOGGER, Y/M/D,
REL, AVG ..these are not available
for the meter but for the meters
with datalogger features named
8205D/8215D/8230D/82100D.
Please contact the store or the
place you purchased.
The LCD is divided into two distinct
sections : One large (Primary) top
screen and one smaller right-
bottom screens (Relative Clock).
The 2 display areas keep you
constantly updated of the pressure
measurements.
The Meter measures Guage
pressure-a measure of pressure in
psi that is reference to ambient
pressure and Differential pressure
-a measure of the difference between
two pressures .

For recording or operating over longer
periods of time, you can disable the
sleep mode by pressing and
simultaneously before power on.
An "n" will appear in the middle of the
screen at which time you can release
the button. (See Fig. A) The
disabled sleep mode will be invalid after
power off.

, i.e. use differential pressure sensor
to measure guage pressure by
leaving one process connection open
to atmosphere and connecting the
second sensor port to your system.

MAINTENANCE
The meter is calibrated in house
before shipping.
To maintain the meter in the good
condition for use , recommend to
calibrate the meter after long time
using.
When properly maintained , the
meter will maintain an accuracy
specification, to ensure your meter
is performing at its peak, send it to
the factory or a qualified instrument
calibration facility for annual
calibration.
Recommend always to set zero
before measurement .Refer to the
zero setting procedure in page 10.
Cleaning:
Ue a damp cloth and mild soap to
clean the case of the Manometer, do
not use harsh detergents or abrasives
as these may mar the finish or
damage the unit's case with an
adverse chemical reaction.
8
CALIBRATION MODE
Calibration mode is only applicable
for a standrad Manometer calibrator
or any qualified meter calibration
facility for annual calibration.

4. The meter has defaulted as 80 psi
calibration point , the adjustable
pressure range is from 78.0 to 82.0
. if calibration pressure source is
not 80psi , to increase the figure by
pressing key , or decrease the
figure by pressing key to set
calibration point as required.
5. Save the calibration point by
pressing key , "SA" and small
"CA"appears on the display (See
Fig. J ) in 2 seconds , the meter
auto-skip to the negative pressure(
-) point for next calibration mode.

1. First , please manually set the
display to zero ( no pressure
applied to the connector ), refer to
the Manual zero procedure.
2. Turn the meter off.
3. Press & simultaneously
,"CA" appears on the display, (See
Fig.I )the meter enters to the
calibration mode ,make sure the
pressure unit to be pointed under
the arrow mark " " is "psi" to
start positive (+) pressure
calibration
DIFDIF

6. Follow the same procedure as step
4 for the negative pressure
calibration point by pressing
key , the LCD now displays" -80.0 "
and small"CA" (See Fig.K ) , do the
necessary calibration figure refer to
your pressure standard if needed.
7. Again save the calibration point by
pressing key, "SA" and "CA"
appears in 2 seconds and then "
End"and "CA" appears in another
2 seconds, the meter turns back to
the normal mode (See Fig. L ).

If you can't save by press key, i.e.
no "SA" appeared , please check : (a)
The cabliration pressure source is
between 75.0 and 85.0, or check (b) if
you enter the right positive pressure
(+) or negative pressure (-) .

If you want to skip positive (+)
calibration when entered to the
Calibration mode , press to skip
to negative (-) calibration point.
Above calibration is an example for
model 82100 , i.e. the pressure range
is from 0 to +100psi (Positive
pressure ) or from 0 to -100 psi (
Negative pressure).

TROUBLESHOOTING
?Power on but no display. Check
the battery are in place and making
good contact or correct polarity ,
replace a new battery or attach
optional AC adaptor for the weak
battery caused.
BAT indication. Replace with a
new battery when LCD display BAT
at the middle bottom.
?
No Display. Make sure battery is
not empty , if the display disappear,
check sleep mode is active . Refer
to the Disable sleep mode function
for a long time using the measure
ment. Or check the tubing is
connected to the meter tightly.
?
?Err.1. For the pressure value
exceed the maximum range , "Err.1
" appears on the display ( See Fig.
O ) ,please change the sensor ,
otherwise, the sensor will be hurt
for going on the overrange
measurement.
Fig.O

?Err.2. For the measurement
pressure is less than minimum
range ,"Err. 2" will appear (See
Fig.P ),recommend to change the
sensor (meter).
Fig. P

?
Err.4. When you set zero ,make
sure you have disconnected the
tubing ,no pressure applied to the
connector. Then if you see an
Err.4 appears on the display , it
means the sensor or meter
damaged (See Fig.R ).Return the
unit to the store you purchased for
repaired .
Err.3.For operating the DIF function
, the differential pressure value is
larger than maximum display digit ,
Err.3 appears on the display (See
Fig.Q ).
?

P.S. Err.4 will be also appeared while
the tube or hose is connecting during
setting zero mode.

Replace your 9-volt battery when:
The BAT icon appears on the right
of the screen.
The meter will not power on.
Use of the back-light causes the
BAT icon to appear.

E1OL or E2UL. When you see the
errors while operating Rs232
software, it means pressure source
is less or over than the range of the
instrument.
REPLACING THE BATTERY
Remove battery from instruments that
you do not plan to use for a month or
more.
Do not leave battery in instrument.
1. Remove the tubing of the
instrument.
2. Lay the instrument face-down on a
clean, flat surface.
3. Remove the battery by screw driver
and observe indicated polarity and
close the cover after replacing with
a new battery.
Even if the battery was recently
replaced, check its voltage level if you
get no response from your instrument.
To replace the battery:

OPERATING CONDITIONS
Compensated temperature range:
o
0~50 C.
