3. Tuote ohiview
The Steinel 11221 Digi-Check 3 consists of a main unit with a digital display and control buttons, and a separate test probe connected by a flexible cable.

Image 1: Steinel 11221 Digi-Check 3 Digital Voltage Tester. The image shows the main unit with a digital display and two orange buttons (HOLD and TEST), and a separate black test probe connected by a grey cable. Both probes have pointed tips.
Komponentit:
- Pääyksikkö: Houses the digital display, LEDs, and control buttons.
- Test Probe (Red): Integrated into the main unit.
- Test Probe (Black): Separate probe connected via cable.
- Digitaalinen näyttö: Näyttää voltage readings and other indicators.
- LED-ilmaisimet: Provide visual feedback for various tests.
- HOLD-painike: Jäädyttää nykyisen lukeman näytössä.
- TEST-painike: Initiates specific test functions (e.g., continuity).
4. Asennus
The Steinel 11221 Digi-Check 3 is ready for use upon receipt. No initial battery installation is required as it is powered via the circuit being tested or an internal power source (if applicable, check product specifications for details on internal power). Ensure the probes and cable are free from damage before each use.
- Inspect the device for any visible damage to the casing, probes, or cable.
- Puhdista anturin kärjet tarvittaessa hyvän sähköisen kontaktin varmistamiseksi.
- Perform a quick functional check on a known voltage source (e.g., a wall outlet) to confirm the device is operating correctly before testing unknown circuits.
5. Käyttöohjeet
5.1. VoitagMittaus (AC/DC)
- Connect the red probe to the positive or live terminal and the black probe to the negative or neutral/ground terminal of the circuit to be measured.
- The digital display will automatically show the measured voltage value (AC or DC).
- Observe the polarity indicator on the display for DC voltage mittaukset.
- Paina PIDÄ -painiketta pysäyttääksesi nykyisen lukeman näytössä. Paina uudelleen vapauttaaksesi painikkeen.
5.2. Phase Testing
To perform a phase test:
- Touch the red probe to the conductor you wish to test for phase.
- Simultaneously, touch the black probe to a known ground or neutral point.
- The device will indicate the presence of phase voltage through an LED or specific display icon.
5.3. Polarity Testing
For DC circuits, the device automatically indicates polarity:
- Kun mitataan DC -tilavuustage, the digital display will show a '+' or '-' symbol next to the voltage reading, indicating the polarity of the red probe relative to the black probe.
5.4. Jatkuvuuden testaus
Tarkista piirin tai komponentin jatkuvuus seuraavasti:
- Varmista, että virtapiiri on jännitteetön ennen jatkuvuustestien suorittamista.
- Touch the red and black probes to the two points you wish to test for continuity.
- Paina TESTATA button (if required, some models automatically detect continuity).
- A low resistance reading (e.g., near 0 Ohm) and/or an audible tone/LED indicator signifies continuity. The device can test continuity up to 500 kOhm.
6. Huolto
- Puhdistus: Pyyhi laite pehmeällä, damp liinalla. Älä käytä hankaavia puhdistusaineita tai liuottimia. Varmista, että laite on kuiva ennen säilytystä tai seuraavaa käyttökertaa.
- Varastointi: Säilytä tilavuustage tester in a dry, cool place, away from direct sunlight and extreme temperatures.
- Anturin tarkastus: Regularly check the test probes and cable for cuts, cracks, or other damage. Replace if any damage is found.
- Virtalähde: As the device is powered by the circuit under test or an internal source, no user-replaceable batteries are typically required. Refer to the product's specific technical data for any internal battery information.
7. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| No reading on display | Ei voltage present; poor contact; damaged probes/cable; internal fault. | Verify circuit is live with another known device; ensure firm contact; inspect probes/cable for damage; if problem persists, contact support. |
| Epätarkkoja lukemia | Poor contact; interference; device malfunction. | Ensure clean and firm contact; test on a known voltage source; if readings are consistently off, contact support. |
| Jatkuvuustesti epäonnistuu | Circuit is open; high resistance; poor contact. | Ensure circuit is de-energized; check for breaks in the circuit; ensure good probe contact. |
