Safety Precautions
If you are using this product for the first time, please pay attention to the
following:
At the beginning of measurement, first open the needle valve on the
instrument measuring pipe, and then adjust the flow with the flow valve on the
panel. If the measurement is finished, the operation will be reversed.
When the instrument is not used for a long time, there will be some air left
in the test pipe and air chamber. Therefore, during the first test, the residual air
will affect the test speed, because the impurities in the air must be removed
before the tested SF6 gas reaches the balance. So we will find that when we
test the second SF6 Electrical equipment and measure it later, the speed will
be very fast (1-2 minutes).
In case of high temperature, we suggest to arrange the measurement
time as far as possible when the temperature is low in the morning, because
the higher temperature will affect the accuracy of measurement.
In the working environment, the product may cause radio interference. In
this case, it may be necessary for users to take practical measures for their
interference.
Please read and keep this manual for future reference.
Check whether the equipment is abnormal before opening.

Ⅰ、Product Characteristics
1. Self calibration: the sensor probe can automatically calibrate the zero point,
automatically eliminate the system error caused by zero point and drift,
and ensure the accuracy of each measurement.
2. Easy operation, large touch LCD screen.
3. Fast gas saving: after starting up and entering the measuring state, the
time for each purity measurement is about 2 min.
4. Self locking joint: the original imported self-locking joint is adopted, which
is safe and reliable without air leakage.
5. Data storage: it adopts large capacity design and can store up to 1000
groups of test data.
6. Clear display: the 5-inch large touch LCD directly displays the current
purity, gas flow, ambient temperature, ambient humidity, time and date, etc.
7. The built-in USB interface can be connected with the PC, and the internal
data of the instrument can be uploaded to the computer through the
supporting software for data analysis.
8. Built in large capacity rechargeable lithium battery, which can work
continuously for more than 10 hours in one charge.

Ⅲ、Operation Method
1. Connecting SF6 devices
Connect the screw end of the measuring pipe with the switch joint, and
tighten it with a wrench;
Close the flow regulating valve on the front panel of the main engine;
Insert one end of the quick connector on the test pipe into the air inlet on
the instrument;
Connect the exhaust pipe to the air outlet.
2. Startup initialization

- 5 -
Turn on the power switch of the instrument, and the
instrument enters the process of initialization and self calibration.
3. Check power
When using the internal battery for power supply, the upper right corner
will display the battery capacity. If the battery capacity shows the red power
shortage sign, please charge it as soon as possible before continuing to use.
This instrument can be used while charging, but the charging time will be
greatly extended.
4. Start measuring
1) When the power is turned on, the instrument will initialize automatically.
After self calibration, it will enter the measurement state automatically.
2) Confirm that the high-precision control valve on the instrument is closed,
and test the quick plug of the pipeline.
3) Connect the other end of the test pipe to the air supply port (or test port) of
the equipment to be tested.
4) At this time, adjust the control valve on the front panel of the solar term
before adjusting the gas flow rate.

5) When measuring the purity of SF6, adjust the flow to about
0.3 SLM (standard liter per minute).
5. Store data
After the measurement data of the equipment is stable, you can save the
data, press the "menu" text on the screen, call up the main menu interface,
select "print data", you can print out the current test data, select "save data",
you can enter the data saving interface.
Press the red "configuration" button to input the test number. After
confirmation, press "save data" in the lower right corner to save the current
data to the instrument. The instrument can save up to 1000 pieces of data.
6. View data

- 7 -
Select "view record" function in the main menu interface. Enter the history
view interface, press the "↑" and "↓" arrows at the bottom, you can turn records
up and down, and press the right down button to print the currently viewed
history.
7. Delete data
Select "delete data" function in the main menu interface to enter the
delete data interface. At this time, press the trash can icon to confirm the
deletion of all data. Press the arrow in the lower left corner to undo the
deletion and return to the main interface.
(Note: data cannot be recovered after confirming deletion)
8. Time Setting

- 8 -
Select the "modify time" function in the main menu to enter the time
modification page. According to the above format, enter the current time, and
press the right-click time modification button to finish the modification. Press
the "←" arrow to cancel the modification and keep the original time
unchanged.
9. Calibration data
Because of changing the calibration data at will, it will seriously affect the
use of the instrument. So we do not open the data calibration function. If
necessary, please contact our technical support
10.After measurement
1) Close the high-precision needle type regulating valve on the instrument.
2) Remove the adapter from the SF6 Electrical equipment.
3) Remove the quick plug between the test tube and the back of the
instrument.
4) Repeat the above steps to test the next data.
5) After all tests are completed, turn off the power.

Ⅳ、Matters needing attention
1. The instrument shall be placed in a safe position to prevent damage and
violent vibration.
2. The instrument shall be charged in time before use.
3. When charging, just connect the power cord to the AC socket without
turning on the power switch, and the instrument will automatically charge.
Generally, the charging time is more than 10 hours.
4. High capacity lithium battery is used inside the instrument because of its
characteristics. Therefore, it is recommended that the instrument be able
to power every 1-2 months when it is not used for a long time. To keep the
lithium battery active.
5. The instrument shall not be put into the aluminum alloy packing box, and
shall be placed on the test bench or instrument rack to prevent dust and
moisture.
6. The instrument shall be calibrated with standard gas once a year. It can be
sent to the manufacturer or authorized unit for calibration to ensure the
accuracy.
