Congratulations on your purchase of the Amprobe MAN02-A manometer. This instrument is

a portable, battery operated pressure measuring device. The MAN02-A is ideal for HVAC/R

technicians measuring pressure level, Medical equipment, Computer peripherals, Pneumatic

controls.

INTRODUCTION

The meter will display all LCD segments when it is ﬁrst turned on for approx. 3 seconds.•

The LCD is divided into two distinct sections : One large (primary) top screen and one smaller•

right bottom screen (relative Clock). The two display areas will constantly update with the

pressure measurements.

FEATURES

The meter measures:

Gauge pressure -• a measurement of pressure that is referred to ambient pressure.

Differential pressure• - a measurement of difference of two pressures .

MAN02-A has 5 selectable units of measure: InH• 2O, psi, mbar, bar, mmH2O.

Please check that the tubing is not leaking or damaged before use.•

STANDARD ACCESSORIES

The package contains:

MAN02-A•

1 9V battery•

Users manual•

2X connection hoses 4mm(ID) x 6mm(OD) x 500mm•

OPTIONAL ACCESSORY

TM-SWA-USB, Download Suite Software with USB cable•

QUICK START

Unscrew battery compartment on the rear of the instrument and insert the battery. Replace

cover and secure with screw.

Press1. �to switch the instrument on.

Press2. to select unit of pressure measurement required. For zeroing, press for

three seconds.

Press3. for differential pressure measurement.

Press4. to freeze the reading on the display. Press again to cancel feature.

Press5. to start a recording; press again to display MAX value of the recording session;

press again to display MIN value of the recording session; and press again to return to real

time recording mode.

www. .com information@itm.com1.800.561.8187

The Instrument records only the Max and the Min values for each session. To record all

values for a recording session, use the Download Suite Software.

Press and hold for 3 seconds to turn clock feature off.

Note: Clock feature available with gauge pressure only, not differential. The instrument will

automatically switch off after 20 minutes unless sleep mode is disabled.

Press6. �to turn ON the back-light. It automatically switches off after 30 seconds.

AUTO POWER OFF

(Sleep mode function)

This instrument will turn off automatically in approx. 20 minutes after power-on if there are

no key activations. For recording or operating over longer periods of time, you can disable the

sleep mode by pressing �and simultaneously before powering on.

An “n” will appear in the middle of the screen at which time you can release the button. (See

Fig. 1) The disable sleep mode will be invalid after power off.

OPERATION MODE

(See Fig. 18.)

Turns instrument on and off.1.

Press momentarily and relative clock starts in the lower right screen.2.

REC is displayed in the middle left of screen (Fig.2).The other functions are locked out except

Power and Backlight.

Press momentarily again and the unit cycles through MAX (Fig. 3) and MIN (Fig.4) and back

to current pressure reading; the record mode is displayed on the LCD.

Press and hold for 3 seconds to turn off the record function and return to normal mode.

Press momentarily to freeze the pressure reading (Fig. 5).3.

Press momentarily,4. 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.6).

Differential Pressure: a measurement 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.

Press momentarily and the units will cycle through5. “InH2O”,”psi”, “mbar”, “ bar”, “mmH2O”

which are indicated on the bottom of the display (See Fig.7 & 8).

Press momentarily and the backlight illuminates for approx. 30 seconds, then turns off6.

automatically.

Press momentarily to decrease the ﬁgure when calibration is being performed.

CALIBRATION MODE

Calibration mode is only applicable for a standard manometer calibrator or any qualiﬁed meter

calibration facility for annual calibration.

www. .com information@itm.com1.800.561.8187

First, manually set the display to zero (no pressure applied to the connector ), refer to the1.

manual zero procedure.

Turn the meter off.2.

Press3. �& 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 from4.

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 pressing5. 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 pressing7. 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:

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

skip to negative (-) calibration point.

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.

www. .com information@itm.com1.800.561.8187

No Display.

Make sure the battery is functional.•

check if sleep mode is active. Refer to disable sleep mode on page.6 to turn it off.•

check if the tubing is connected to the meter tightly.•

Err.1.

For the pressure value exceeding the maximum range, “ Err.1” appears on the display (See Fig.

14). Do not exceed rated over pressure range of manometer. Sensor may be damaged.

Err.2.

For the measurement pressure less than minimum range, “Err. 2” will appear (See Fig. 15).

Err.3.

For a differential pressure value larger than maximum display, “Err.3” appears on the display

(See Fig.16 ).

Err.4.

When you set zero, make sure you have disconnected the tubing. If you see an “Err.4” appear

on the display, it means the manometer is damaged (See Fig.17)

Note. Err.4 Will be also appear If the tubing is connected during zero set.

E1OL or E2UL.

When you see these errors while operating USB software, it means pressure source is less or

over than the range of the instrument.

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.•

Replacing The Battery

Even if the battery was recently replaced, check its voltage level if you get no response from

your instrument.

To replace the battery:

Remove the tubing from the instrument.1.

Lay the instrument face-down on a clean, ﬂat surface.2.

Remove battery cover.3.

Remove battery from instruments that you do not plan to use for a month or more.

Do not leave battery in instrument.
