6. Käyttöohjeet
6.1. Kytke virta päälle
Once correctly wired and powered, the display will illuminate and show the current temperature measured by the probe.
6.2. Viewlämpötila
The primary function of the device is to continuously display the temperature. The reading will update automatically as the temperature changes.
6.3. Accessing Settings (SET Button)
The "SET" button is used to access and modify various parameters of the device, such as temperature units (°C/°F) and probe type (NTC/PTC). Specific programming steps will depend on the firmware version. Generally:
- Lyhyt painallus: May display a specific parameter or confirm a selection.
- Pitkä painallus: Typically enters programming mode or saves changes.
Consult the full programming guide for detailed instructions on setting specific parameters, including temperature alarms or calibration, if applicable to your model.
7. Huolto
7.1. Puhdistus
To clean the display unit, gently wipe the surface with a soft, dry, or slightly damp cloth. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the display or casing.
7.2. Probe Inspection
Periodically inspect the temperature probe and its cable for any signs of damage, wear, or corrosion. Replace the probe if any damage is observed to ensure accurate readings.
8. Vianmääritys
| Ongelma | Mahdollinen syy | Ratkaisu |
|---|---|---|
| Ei näyttöä / Laite ei käynnisty | No power supply; Incorrect wiring (polarity); Faulty unit. | Check 12V DC power connection and polarity. Ensure power source is active. Verify wiring. If problem persists, contact support. |
