Manometer

DD890

Introduction

The device measures Gauge/Differential Pressure

from -200 mbar to 200mbar (+-80.29 in H2O), it features

11 selectable units of measure: inH20 , psi , bar , mbar,

kPa , inHg , mmHg ,ozin

,ftH20 , cmH20, kgcm

Additional features include Data Hold. Auto Power Off

disabled , and an USB for capturing reading to a PC

using optional software . Careful use of this meter will

provide years of reliable service.

Operation

1.Power

Press the ON/OFF button to turn power on or off.

The meter will perform a short self-test when turned on.

The meter defaults to the setting used during the last

operation.

2.ZeroAdjust and Offset

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“oooo ”

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.

4. 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. If the pressure value

is over the range, error codes will show on the screen.

Press the HOLD button again to return to normal

operation.

4.Record

The MAX/MIN mode allows the user to view only

the highest (MAX) , lowest (MIN)or average (AVG)

readings with relative time stamp.

1. Press the REC button once and REC 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 REC Button again and MAX appears on

the display .The display is now showing the

maximum pressure and relative time that 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

MAX/MIN /AVG measurements.

6. To exit the MIN/MAX/AVG mode, press the

REC button for 3 seconds to return to normal

operation.

5.Backlight Display

Press the Backlight button to turn on the

backlight. It will remain on for 40 seconds.

6.Automatic Power Off

Off , hold down the HOLD button and turn on the meter

on , An “n”will appear in the display indicating that

Auto Power Off mode is disabled. The meter will return

to normal operation when it is turned off.

7.Units

Press the Unit button momentarily and the meter will

cycle through the 11 available units of measure as

indicated by the cursor on the bottom of the display.

USB

The meter has a USB port for use with the optional PC

interface DataAcquisition Software./Hardware kit.

Error Codes

An error message will appear on the display if the

meter fails an internal diagnostic test. And it will freeze

all the buttons.

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. Err4: DIF function, the differential pressure value is

below range.

Battery Replacement

When the battery power falls low ,“BAT”will

appear on the LCD. Replace the 9V battery .
