- Pastikeun éta dipasang pageuh sareng henteu oyag.
6.2. Diagram Kabel
Refer to the diagram below for correct wiring. Incorrect wiring can damage the device or lead to hazardous conditions.

Figure 5: Wiring Diagram for GV-1P (left) and GV-3P (right)
- GV-1P (Single Phase Voltmeter): Sambungkeun input voltage to terminals 1 and 2. The display will show 'V~'.
- GV-3P (Three Phase Voltmeter): Connect phase 1 to terminals 1 and 2 (V1~), phase 2 to terminals 3 and 4 (V2~), and phase 3 to terminals 5 and 6 (V3~). The display will show 'V1~', 'V2~', and 'V3~' sequentially.
Important Note: This product is not suitable for use with frequency converters, inverters, or in power environments with high harmonic interference. Such conditions may lead to inaccurate readings or damage to the device.
7. Operasi
Once properly installed and wired, restore power to the circuit. The voltmeter will automatically power on and display the measured AC voltage(s) on its LED screen. For the GV-3P model, the display will cycle through the voltages of each phase (V1, V2, V3).
- Maca Tampilan: The bright red LED display provides clear numerical readings of the voltage.
- Akurasi: The device provides readings with a ±2% discrepancy range.
