Click [confirm] to return to the history data interface.
5. Save interface
The save interface is as shown in the following picture:
After entering the “save interface”, you’ll see such touch buttons as
[confirm], [measure] and [print].
Press [confirm], and the system will automatically save data for you. If the
data is successfully saved, you’ll enter the following interface.

- 10 -
At the time, touch [confirm] button, and the system will return to the
“measurement data interface”.
6. System settings
1) The system setting interface is as shown in the following picture：
After entering the “system setting interface“, you’ll see such touch buttons
as [help], [demarcate], [settings], [set time] and [measure].
In the “system help interface”, there are some notes for the use of the
meter. Feel free to call us at the phone number indicated on the warranty card
and use instructions if you are still not quite clear about any parts during your
use of our product.
2) Click “demarcate”, and the meter will enter the “system calibration
interface”.

Ⅵ、Precautions
This instrument is SF6 leak detector,The following points should be noted:
1. Opening or closing the power in dangerous area is prohibited!
2. Charging the battery in dangerous area is prohibited!
3. Preventing collision, extrusion and strenuous vibration during
transportation or measurement process
4. Please charge the battery in time when the electricity indicator shows
deficiency in the using process of the instrument. It is only required to plug
the socket into 220V power. There is no need to open the power switch.
The battery will be charged automatically. The charging indicator light is
illuminated and it will be quenched after completing the battery charging.
5. Do not operate the instrument under electrification when connecting with

- 13 -
the communication cable. the instrument and computer are assumed to be
closed. Or the communication interface is easy damaged.
6. The instrument should be charged with enough electricity. It is required to
check whether the electricity is enough or not frequently.

Appendix: Frequently Asked Questions
1. How much time is needed for battery charging? When there is need to
charge battery? When will the battery charging finish?
The charging time is different corresponding to the actual remaining
electric quantity. Generally speaking, it is less than 12 hours. Please charge
the battery once the electricity quantity shows deficiency. It is inappropriate to
use up the electricity in order to ensure the service life of battery. There is over
charge protection in the charging circuit. The charging indicator light will be

- 14 -
quenched after finishing the battery charging.
2. When there is need for calibration and maintenance for the instrument?
Generally speaking, it is recommended to calibrate every two years, or
twice a year under special circumstances (when the gas route pollution is
severe)
3. The instrument is stagnated and the data is decreased in the
measurement process, what is the reason?
The sensor is implementing the function of gain regression. In other
words, it will return to the previous measurement process for calibration. At
this time, the interface data remains the same, while the CPU is processing
the data. Therefore, the date will decrease after a little while.
