◆Measure air flow, velocity, temperature, humidity, atmospheric pressure at the same time.
◆Two kinds of tests are available for supply flow and exhaust flow.
◆Back pressure compensation.
◆Ultra-large storage capacity: 8000 records, which can be printed or transferred to the computer.
◆Blue tooth communication makes remote monitoring and data transferring available.
◆Can be connected to a Bluetooth printer, which is to print test data in real time.
◆Low power consumption. Battery power supply can work continuously for 14 hours. But if no operation
for a long time, it can enter power saving mode.

Note: The poles always cross in an “X” shape when assembling. To remove the poles, simply reverse the step
3．Installations of micro-manometer and portable handle
Note：1）Release the poles and portable handle when packing in the carring case to avoid case damaged.
2）The micromanometer number corresponds to the base number one by one
3.2 Velocity Grid Installation
Air velocity testing can be achieved when micromanometer works together with the velocity Grid.
Note: Mounting angle between the Grid and handle can be adjusted as request.
3.3 Pitot Tube Installation
Air flow and velocity testing can be achieved when micro-manometer work together with Pitot tube.
3.4 Micromanometer Installation
Differential pressure testing can be achieved by using the micromanometer.

4. Operation Directions
4.1. Power Supply
1．Power by AC adapter.AC adapter will be as the priority power supply when the AC adapter and batteries are
capable of using. The specification of theAC adapter is: I/P:AC 110-240V 50/60HZ O/P:DC 5V/2A。
1）AC adapter for the master. 2）AC adapter for Capture Hood
2．Power by batteries.
◆Powered by 4 AA-size batteries, with the battery compartment cover open, install the batteries (please pay
attention to the polarity of the batteries).
◆Alkaline battery or rechargeable Ni-MH battery can be used. Never mix battery types, or battery leakage or
damage to the instrument may occur.
◆When power is supplied with batteries, the current charge value will be displayed on the upper of the LCD.
When the batteries run out of power, the instrument will turn off.
Note：
1）The test may stop if the battery is low during testing.
（-）（ +）
Turn Off

2）Don't use a full_power battery with low power batteries.
3）It is recommended you change batteries when the power shows low.
4.2 ON/OFF
1. Getting Started
Press【POWER】for two seconds, and the instrument will turn on,displaying “KANOMAX”then enter into
the testing interface.
2. Shut Down
Press【POWER】for two seconds, and the instrument will turn off automatically.
4.3 Back pressure plate
Note：
1）When testing in non-back pressure mode, please keep the back pressure plate.
2）When the air flow is greater than 1500m3/h, It is recommended to use the back pressure mode test and
follow the prompt steps to test.
5.Functions Test
Besides the airflow test, if along with other optional products, test air velocity and micro-differential pressure is
available.

Note：
1）START: Left-button for the micromanometer or instrument base.
2）After testing start for about 8s with stably measuring, output displaying the test data and testing wind
direction.
3）Testing stop when finish outputting.
4）After the measurement stops, press “SAVE”to record the testing value, if you do the “Cycle”No.

2）Go on the testing with frequency of 1s for data updating.
3）The continuously outputting is as the average data and be related with the “Damp Per.”set by user.
More larger of the value of ”Damp Per.” will get more stable of the testing data.
4）If the storage period "Cycle Per." is not 0, the data will be stored according to the time set by "Cycle
Per.", and the "Cycle" will increase automatically.
5）Press “STOP”, testing stop.
6）Same testing method with the capture hood when using the Velocity Grid、Pitot、Micromanometer.
5.1.3 Back Pressure Compensation Measurement Mode
In order to reduce the measure error of the pressure loss, which causing from the hood to the
system and get the more real air flow, we suggest testing under the Back Pressure Mode when air
flow is more than 1500 m3 /h.

Plate as needed.
2）Press START for about 8s, testing stop, real airflow outputting with back pressure compensation.
3）When select Velocity Grid、Pitot tube、Micromanometer for testing, Back Pressure Compensation will
be not available.
5.1.4 Print Settings
The 6720 can be connected to our dedicated portable Bluetooth printer to print test data at any time (the
format is as shown in the figure below). Please refer to chapter 5.2.4 of the manual for the connection process of
the Bluetooth printer.
Note：
1）Please purchase our dedicated Bluetooth printer, and the printer icon will be displayed in the status bar
after the connection is successful.
2）In single test and back pressure test mode, print when the test result is formed.
3）In continuous test mode, print once per 1s according to the update frequency of test results.
5.1.5 Tools Settings
The TABmaster Model 6720 is an instrument for airflow, air temperature, and relative humidity
measurements. The optional accessories (Velocity Grid, Pitot tube, and Micromanometer) expand the
parameters that the instrument can measure. Refer to the Chapter 3 and 5 for details.
