Instrument Operation

1.Menu introduction

After turning on the power, the instrument enters the main interface, and there are four menu options on the main interface, showing current temperature and humidity, battery power and system time. The main interface is shown in Figure 1.

Figure 1

1). Test

① Under the main interface, click on the “ TEST “, the instrument will enter the measurement interface and the instrument will show the measured SF6 purity value(percentage content), gas flow, ambient temperature, ambient humidity, and current system time. The interface is shown in Figure 2:

Figure 2

② Under the measurement interface, press “ CURVE ” to enter the curve tracking display interface. Press “ SAVE ” to enter the data saving interface, and the test data can be saved according to the instructions of the instrument. Press “ BAKE ” to exit the measurement state back to the main operation interface.

③ Under the data saving interface, click on the blank space of the edit box on the right of the device number. After the cursor is displayed, press the right numeric keypad, enter thedevice number, and press the “ OK ” key to save the test data and enter the data query. Interface. Press the “ Cancel ” to exit the data saving interface and return to the measurement state. As shown in Figure 3:

2. Instrument calibration

Click “ Calibration “, enter the password and press “Enter” to enter the instrument calibration interface. This function must be performed when the instrument needs calibration, and the manufacturer shall be returned to the manufacturer for operation.

Figure 8

Note: “ Valid ” means that the data of the bank is Valid, and “No Valid” means that the data of the bank is invalid and does not participate in the calculation. Click “No Valid” or “Valid” to switch the valid invalid flag.

Click the “ SELECT ” button to switch the six rows of data and highlight a line, asshown in the figure 9.

Figure 9

Click on the imaginary area of figure 9 and the number keyboard will pop up. Enter the percentage of purity of the standard gas, as shown in the figure 10. After the input is completed, click “ OK ” to return.

When the calibration is complete, the instrument will exit the calibration interface and save the current data.
During the calibration process, click the “ SAVE ” key to save the current data, and exit the calibration interface. Press the “ BACK ” key to exit the Auto-Calibration and do not save the current data.

Operation Steps

1. Warm up the machine for ten minutes. This process eliminates the effect of ambient temperature on the test results.
2. Connect SF6 device

1. Connect the thread end of the measuring pipe with the switch connector and tighten it with a wrench.
2. Then insert one end of the fast joint on the test pipe into the sampling port on the purity meter.
3. Connect the exhaust pipe to the vent.

3. Check the charge
   When using DC power, please check the battery power displayed in the upper right corner. If the power is less than about 20%, please turn it off and continue to use it after charging.

4. Start measurement
   First, all the needle valves on the pipe are measured, then the flow valve on the purity gauge panel is adjusted. The flow rate is adjusted to about 0.5L/M, and the gas purity of SF6 is measured.

5. Store data
   After the equipment measurement is completed, the data can be saved in the instrument, and the operation menu can be adjusted according to the “HISTORY” key.

6. Measuring other equipment
   After measuring a device, close the needle valve on the measuring line and the regulating valve on the purity meter. Remove the adapter from the SF6 electrical equipment. If you need to continue to measure other devices, follow the above steps to continue measuring the next device.

7. End of measurement
   After the measurement is finished, turn off the purity instrument.

Maintenance and Service

1. Replace the printing paper
   Press the button on the left and load the paper into the printer as shown on the right, and close the front cover.

Matters need attention

1. The instrument should be placed in a safe position to prevent falls and avoid violent
   vibrations.

2. Do not measure corrosive gas.

3. When adjusting the gas flow, the flow valve should be slowly opened, so that the flow indicator within the range of 0.5 ~ 0.8 L/minute.

4. Before the instrument is used, it should be charged in time. When charging, simply insert the instrument’s own power adapter into the charging port. Without turning on the instrument’s power switch, the instrument will automatically charge. The charging time usually takes more than 5 hours.
