6. If Uc > Ulim, the alarm will ring, and pressing any button will silence the alarm.
7. Press "MEMO" as required to store test result.
8. If the display shows ⚡ then the live line is opposite direction to null line. The measurement will not perform.

RCD Measurement

1. Rotate the knob to one level of RCD x1/2, RCD x1, RCD x5.
2. Select the test parameter according to actual situation, press SET, then press ▲▼ to select, such as IA (10mA/30mA/100mA/300mA/500mA), then press SET again, press to set test current polarity (0° and 180°), then press SET or ENTER to return again.

4. Press "MEASURE" to start measuring.
5. Trip out time will display on the main-screen, while Uc voltage will display on the sub-screen.
6. If trip out time > 300mS (S mode is 500mS), the alarm will ring, and pressing any button will silence the alarm.
7. Press "MEMO" to store the test result.
8. If the display shows ⚡ then the live line is opposite direction to null line, and the measurement will not perform.

Battery Replacement

⚠️ Warning

To avoid the electric shock, before replacing the battery and opening the back cover of meter, please be sure that the meter is powered off and test pen is not connected with any circuit to be tested. Please ensure that battery cover is installed well before using meter. Only a battery with the same model or electrical specifications should be replaced.

If ? is displayed on the screen, it means that the battery load voltage is lower than the lowest voltage guaranteeing the measurement error limit, and the meter alarm will sound. The battery should be replaced with a new one. Please replace the battery according to the following steps:

1. The test pen should be disconnected from the test circuit. Rotate the functional shift knob to "OFF" position, and remove the test pen from the input jack.
2. Use a screwdriver to remove the battery cover screw and open the battery compartment. The battery cover can be moved downward. Don't use a sharp tool to open it forcibly, otherwise, the enclosure will be damaged.
3. Take the old batteries and replace them with six 1.5V batteries. Be careful to not mix new batteries with old batteries.
4. Replace the battery cover and return the screw, securely.
