5. Návod k obsluze
Once properly connected, the KWS-DC26 meter will automatically power on and begin displaying measurements.
5.1 Zobrazení nadview
The color LCD displays various parameters simultaneously:
- svtage (V): Current DC voltage.
- Proud (A): Proud DC amperage. Arrows indicate direction (charge/discharge).
- Výkon (W): Instantaneous power consumption/generation.
- Energie (Wh): Accumulated energy in Watt-hours.
- Kapacita (Ah): Accumulated charge/discharge capacity in Ampere-hours.
- Časovač: Elapsed time of measurement.
- Teplota (°C): Real-time temperature from the connected thermostat.
5.2 Bidirectional Measurement
The meter automatically detects the direction of current flow. Arrows on the display will indicate whether current is flowing into (charging) or out of (discharging) the connected battery or system.
5.3 Alarmy
The KWS-DC26 includes alarm indicators for:
- Přepětítage: Alerts if the voltage exceeds a safe limit.
- Nadproud: Alerts if the current exceeds a safe limit.
- Přes teplotu: Alerts if the monitored temperature exceeds a safe limit.
When an alarm triggers, the corresponding indicator on the display will activate. Address the cause of the alarm immediately to prevent damage to the meter or connected equipment.
5.4 Data Logging and Memory
The meter continuously logs energy (Wh) and capacity (Ah) data. In case of power loss, the built-in power failure memory ensures that accumulated data is retained. The timer function tracks the duration of the measurement session.
5.5 Vymazání dat
The meter features a 'Time clear' function, which typically allows you to reset the accumulated energy (Wh), capacity (Ah), and timer data. Refer to the device's physical buttons or on-screen menu (if applicable) for specific instructions on how to perform a data clear.
6. Údržba
To ensure the longevity and accurate performance of your KWS-DC26 DC Power Meter, follow these maintenance guidelines:
- Čištění: K čištění zařízení používejte měkký, suchý hadřík. Nepoužívejte abrazivní čisticí prostředky ani rozpouštědla.
- Skladování: Měřič skladujte na chladném a suchém místě mimo dosah přímého slunečního záření a extrémních teplot.
- Zacházení: Handle the device with care to avoid physical damage. Do not drop or expose it to excessive vibration.
