- Locate the battery compartment on the back of the device (refer to Figure 2).
- Unscrew the screws to open the battery cover.
- Insert six AAA batteries, ensuring correct polarity.
- Close the battery cover and secure it with the screws.
7. Operating Instructions
The main test items are located below the display screen, including Voltage (V), Voltage Drop (Vd), Impedance (Z), RCD, and GFCI. Use the FUNC key to cycle through these main functions.
7.1 Voltage Measurement
This function provides real-time display of the true effective value of voltage, wiring status, and frequency. It includes three sub-menus: Phase voltage (L-N), Zero line to ground voltage (N-E), and Peak voltage (Peak).
- Press the FUNC key until 'V' is selected.
- Use the Up/Down arrow keys to select L-N, N-E, or Peak.
- Press the TEST key to initiate measurement.
Normal Measurement Results:
- Phase voltage: 198-242V (108-132V)
- Zero line to ground voltage: <2V
- Peak voltage: 280-342V (153-185V)
- Frequency: 50Hz / 60Hz
Warning: The maximum measured voltage cannot exceed 265V!
7.2 Voltage Drop Measurement
This test displays the real-time wiring status and true RMS voltage drop under current load. This test includes three sub-menus: 5A, 8A, and 10A loads.
- Press the FUNC key until 'Vd' is selected.
- Use the Up/Down arrow keys to select 5A, 8A, or 10A load.
- Press the TEST key to initiate measurement. The instrument adds a simulated load to the live line (phase line) and zero line (neutral line) and calculates the voltage drop.
Normal Measurement Results: Voltage drop <5%.
7.3 Cable Impedance Measurement
This function measures the real-time display of wiring status and frequency, and displays impedance test results. It includes four sub-menus: Line-Neutral (L-N) conductor impedance, Line-Earth (L-E) conductor impedance, Neutral-Earth (N-E) conductor impedance, and Effective Short-Circuit Current (ASCC).
- Press the FUNC key until 'Z' is selected.
- Use the Up/Down arrow keys to select L-N, L-E, N-E, or ASCC.
- Press the TEST key to initiate measurement.
Normal Measurement Results:
- Impedance of live line zero line conductor (Line 1.4 (2.0mm²) <0.1 Ω/m; Line 1.2 (3.3mm²) <0.1 Ω/m; Line 1.0 (5.2mm²) <0.03 Ω/m)
- Ground wire conductor impedance (ensuring personal safety <1 Ω; ensuring equipment safety <0.25 Ω)
7.4 RCD Testing
RCD test displays the real-time wiring status and the performance of the leakage protector by simulating a current greater than 30mA between the live wire and the ground wire.
- Press the FUNC key until 'RCD' is selected.
- Press the TEST key to initiate measurement.
Normal Measurement Results: RCD test (triggered within the specified time of RCD). The calculation formula for UL prescribed trigger time: T=(20/I) * 1.43 (T: Trigger time in seconds, I: Trigger current in milliamperes).
Important: Before testing, check if there are important loads in the circuit, and if necessary, turn off the load before testing. If RCD is to be tested in a two-wire system (without a ground wire), an additional ground wire is required to measure it.
7.5 GFCI Measurement
GFCI test displays the real-time wiring status and the current triggering current and tripping time of GFCI.
- Press the FUNC key until 'GFCI' is selected.
- Press the TEST key to initiate measurement.
Normal Measurement Results: GFCI test (GFCI is triggered within the specified time to power off the tested line). If the GFCI device is not triggered, the instrument automatically stops testing after 6.5 seconds.
Important: Before testing, check if there are important loads in the circuit, and if necessary, turn off the loads before testing. If GFCI is to be tested in a two-wire system (without a ground wire), an additional ground wire is required to measure it.
7.6 Wiring Status Detection
After the instrument is connected to the tested socket, the result of "wiring status" is immediately displayed on the screen.
| Wiring Status | Screen Display (L E N) | Explanation |
|---|---|---|
| Normal | ⚪⚪⚪ | Bright |
| No ground wire | ⚪⚪ | Exterminate (E is off) |
| Fire/zero connection reversed | ✨✨ | Flicker (L and N flicker) |
| Other statuses | ⚪⚪⚪ | Refer to manual for specific interpretation |
Note:
- Line voltage cannot be detected (voltage between two live wires).
- Unable to detect combined faults.
- The reverse connection between ground wire and neutral wire cannot be detected.
