2. Segurtasun informazioa
WARNING: Electrical shock hazard. Installation should only be performed by qualified personnel. Always disconnect power before installation or maintenance.
- Ensure all power is disconnected at the main circuit breaker before attempting any wiring.
- This meter is designed for use with pure AC 50-60Hz power supplies only. Do not use with square wave, inverter output, or modified sine wave circuits, as this will damage the meter.
- Verify correct wiring connections as shown in the installation diagram to prevent damage to the instrument or electrical hazards.
- Ez gainditu zehaztutako bolumenatage (AC 80-300V) or current (100A) ratings.
- Operate within the specified temperature range of 14°F~149°F (-10℃ ~ 65℃).
3. Konfigurazioa eta instalazioa
Careful installation is essential for proper function and safety. Refer to the wiring diagram below.

Instalazio urratsak:
- Potentzia deskonexioa: Turn off the main power supply to the circuit where the meter will be installed. Confirm power is off using a voltage probatzailea.
- Panelaren mozketa: Create an installation hole of 68x38mm (2.68×1.5 inches) in your panel or enclosure.
- liburukiatage Input Wiring: Connect the AC 80-300V power supply (live wire and neutral wire) to the two green terminals labeled 'voltage' on the meter. These terminals also power the meter.
- Current Transformer (CT) Installation:
- Pasatu alanbre bizia of the load circuit through the hole in the middle of the current transformer (CT). Ensure only the live wire passes through the CT.
- Connect the two blue wires from the CT to the two blue terminals labeled 'current' on the meter. The polarity of these wires does not matter.
- Secure the Meter: Insert the meter into the panel cutout and secure it in place.
- Azken egiaztapena: Double-check all wiring connections against the diagram to ensure they are correct and secure.
- Energia berreskuratzea: Restore power to the circuit. The meter should power on and display voltage eta egungo irakurketak.
Important Note: Connecting the voltage input and CT secondary wires incorrectly will damage the instrument.
4. Funtzionamendu-argibideak
Once properly installed and powered, the KETOTEK Digital AC Ammeter Voltmeter operates automatically.
Pantaila irakurtzea:
- The upper display, illuminated in gorria, indicates the AC Boltage (V).
- The lower display, illuminated in berdea, indicates the AC Korrontea (A).
4.1 irudia: Gertuko planoa view of the meter's dual-color LED display showing voltage eta egungo irakurketak.
The meter continuously monitors and displays the real-time voltage and current of the connected AC circuit. No user interaction is required for basic operation.
5. Mantentzea
The KETOTEK Digital AC Ammeter Voltmeter requires minimal maintenance.
- Garbiketa: Erabili zapi leun eta lehor bat pantaila eta c garbitzeko.asing. Ez erabili garbitzaile edo disolbatzaile urratzailerik.
- Ingurumen-baldintzak: Ensure the meter is operated within its specified temperature range (14°F~149°F / -10℃ ~ 65℃) and in a dry environment to prevent damage.
- Ikuskapena: Periodically inspect the wiring connections for any signs of wear, corrosion, or loosening. Address any issues promptly after disconnecting power.
6. Arazoak
If you encounter issues with your KETOTEK Digital AC Ammeter Voltmeter, refer to the following common problems and solutions:
| Arazoa | Kausa posiblea | Irtenbidea |
|---|---|---|
| No display or incorrect voltagirakurketa. | No power to voltage input terminals, incorrect voltage wiring, or voltage outside specified range. | Verify power supply to the green voltage input terminals (AC 80-300V). Check wiring connections for continuity and correct polarity. Ensure the measured voltage is within the 80-300V AC range. |
| Incorrect current reading or 0.00A displayed when load is active. | CT not correctly installed, CT wires disconnected, or current too low to register. | Ensure the live wire of the load passes through the CT. Verify the blue CT wires are securely connected to the meter's current terminals. Confirm the load is drawing current. |
| Meter damaged or erratic readings. | Used with incompatible power supply (e.g., square wave, inverter output, modified sine wave) or incorrect wiring. | This meter is only for pure AC 50-60Hz. Discontinue use if an incompatible power source is suspected. Review wiring diagram carefully for any errors. If damage has occurred, replacement may be necessary. |
