5. Inställning
5.1. Batteriinstallation
The scale is powered by 5 AAA batteries. Ensure batteries are correctly installed in both the scale platform and the remote control unit.
- Locate the battery compartment on the underside of the scale platform and on the back of the remote control unit.
- Open the compartments and insert the AAA batteries, observing the correct polarity (+/-).
- Stäng batterifacken ordentligt.
5.2. Initial placering
Place the scale platform on a firm, level, and stable surface. Ensure there are no obstructions that could interfere with the weighing process.
Image: The remote control unit can be conveniently stored within the scale platform for transport and protection. The image also indicates the scale's dimensions and battery type.
6. Bruksanvisning
6.1. Powering On and Self-Test
Tryck på DRIVA button on the remote control unit to turn on the scale. The scale will perform a self-test, which typically completes within 2 seconds.
Image: The scale initiates a self-test upon power-on and features an automatic shutdown if no weight change occurs for 10 minutes.
6.2. Val av enhet
Tryck på ENHET button to cycle through the available measurement units: Kilograms (KG), Pounds (LB), and Ounces (OZ). Select the desired unit before weighing.
Image: The scale supports three optional units: Kilograms (KG), Pounds (LB), and Ounces (OZ), selectable via the UNIT button.
6.3. Nollställningsfunktion (tarafunktion)
To measure the net weight of refrigerant, use the tare function.
- Place the empty refrigerant tank or container on the scale platform.
- Vänta tills avläsningen har stabiliserats.
- Tryck på NOLL knappen. Displayen återställs till 0.000.
- Begin charging or recovering refrigerant. The display will show the net weight of the refrigerant added or removed.
Image: The remote control unit highlights the functions of its buttons: POWER (turn on/off), ZERO (clear current reading), UNIT (switch units), and LAMP (turn on/off backlight).
6.4. Bakgrundsbelysningskontroll
Tryck på LAMP button to turn the LCD backlight on or off. This is useful for reading in various lighting conditions. The backlight will automatically turn off after 10 seconds of inactivity to conserve battery, or it can be set to always on.
6.5. Överbelastningsvarning
If the weight on the platform exceeds the maximum capacity (100 kg / 220 lbs), the display will show "FULL" and an audible alarm will sound. Immediately remove some weight to prevent damage to the scale.
Image: The remote control unit indicates an overload by displaying "FULL" and emitting a beep, protecting the sensors from damage.
6.6. Remote Control Placement
The remote control unit features a swivel bracket and a hook, allowing it to be placed on the ground or hung for optimal viewunder drift.
Image: The remote control unit is equipped with a 360-degree swivel bracket, making it easy to read whether placed on the ground or hung.
7. Underhåll
7.1. Städning
Wipe the scale platform and remote control unit with a soft, damp trasa. Använd inte slipande rengöringsmedel och doppa inte enheten i vatten.
7.2. Förvaring
When not in use, store the scale in its nylon carrying bag in a dry, cool place. Remove batteries if the scale will not be used for an extended period to prevent leakage.
7.3. Batteribyte
The LCD display indicates battery life. Replace batteries when the low battery indicator appears to ensure accurate operation.
8. Felsökning
| Problem | Möjlig orsak | Lösning |
|---|---|---|
| Vågen slås inte på. | Döda eller felaktigt installerade batterier. | Kontrollera batteripolariteten och byt batterier vid behov. |
| Felaktiga avläsningar. | Unstable surface; scale not zeroed; exceeding capacity; external interference. | Place on a stable surface. Press NOLL before weighing. Ensure weight is within capacity. Avoid strong vibrations or drafts. |
| "FULL" displayed and alarm sounds. | Överbelastningstillstånd. | Immediately remove weight from the platform until the display clears. |
