4. Persediaan
Pemasangan Bateri:
The UT12 series (UT12D, UT12E, UT12M) requires 2x 1.5V AAA batteries (not included). The UT15C, UT18C, and UT18D models typically come with integrated power or use standard batteries. Refer to the battery compartment on your specific model for correct polarity and installation. Ensure the battery cover is securely fastened before use.
5. Arahan Operasi
5.1 General Operation (UT15C, UT18C, UT18D)
The following video demonstrates key measurement functions of the UT18C/D models:
5.2 AC/DC Jldtage Measurement (UT15C, UT18C, UT18D)
- Connect the test probes to the circuit points where voltage perlu diukur.
- The device will automatically detect AC or DC voltage and display the reading on the LED indicators or LCD screen (UT18C/D).
- Rujuk voltage indication scale on the device for approximate voltage peringkat.
5.3 Continuity Measurement (UT15C, UT18C, UT18D)
- Ensure the circuit is de-energized before performing continuity tests.
- Touch the two test probes to the ends of the conductor or component you wish to test.
- A buzzer will sound and/or an LED will illuminate if continuity is detected (resistance typically below 100kΩ).
5.4 Phase Rotation Test (UT15C, UT18C, UT18D)
This function is used to determine the phase sequence of a three-phase system (voltage range 0V-690V, frequency 50Hz-60Hz). Follow the specific instructions on your device for proper probe placement to identify phase rotation.
5.5 RCD Measurement (UT18C, UT18D)
The UT18C and UT18D models can perform RCD (Residual Current Device) tests. Insert the probes into the appropriate terminals of the RCD-protected circuit and activate the test function as per the device's interface. This checks if the RCD trips correctly.
5.6 Vol. AC Tanpa Kenalantage Detection (UT12D, UT12E, UT12M)
- Hidupkan peranti.
- Bring the tip of the detector close to the conductor or outlet.
- Peranti akan menunjukkan kehadiran volum ACtage through visual (LEDs) and/or audible (buzzer) signals.
- UT12E/M models feature High (90V-1000V AC) and Low (24V-1000V AC) sensitivity modes.
5.7 Live/Neutral Wire Identification (UT12D, UT12E, UT12M, UT18C, UT18D)
This function helps distinguish between live and neutral wires. For non-contact models (UT12 series), the device will typically give a stronger indication (e.g., faster flashing LED, louder beep) when near a live wire. For contact models (UT18C/D), specific probe placement or a dedicated function may be used.
5.8 Breakpoint Detection (UT12D)
The UT12D can detect breakpoints in a live wire. Move the detector along the wire; the sensing signal indicator will flash where power is present and will not light up past the disconnection point.
5.9 Fungsi Lampu Suluh
Many models, including the UT12 series and UT15C/UT18C/UT18D, include a built-in LED flashlight to assist in dimly lit work areas.
6. Penyelenggaraan
- Pembersihan: Lap peranti dengan iklanamp kain dan detergen lembut. Jangan gunakan pembersih atau pelarut yang melelas.
- Storan: Simpan peranti di tempat yang kering dan sejuk jauh dari cahaya matahari langsung dan suhu yang melampau.
- Penggantian Bateri: If the low battery indicator appears, replace the batteries promptly to ensure accurate readings. For UT12 series, open the battery compartment and insert new 1.5V AAA batteries with correct polarity.
- Penentukuran: Untuk kegunaan profesional, penentukuran berkala oleh pusat servis yang berkelayakan adalah disyorkan untuk mengekalkan ketepatan.
7. Penyelesaian masalah
- Peranti tidak dihidupkan: Periksa pemasangan bateri dan pastikan bateri tidak kehabisan kuasa.
- Bacaan tidak tepat: Ensure proper contact with the circuit, check battery level, and verify the device is within its operating temperature range.
- No detection (non-contact models): Ensure the device is in the correct sensitivity mode (High/Low) for the expected voltage.
- Intermittent readings: Check for loose connections or damaged probes.
