Bezpečnostní opatření
Always observe the following safety guidelines to prevent damage to the device or injury:
- Prevent Burning Warning: When testing high-voltage batteries or large power sources, ensure both current adjustment knobs are turned fully counter-clockwise to their minimum (zero) position before connecting the power source. After connection, slowly adjust the current knob according to the desired power. Do not instantly transfer to full power, as this can cause excessive instantaneous power load, risking damage to the discharge tube.
- The body discharge power must not exceed 150W to prevent burnout.
- Ensure proper polarity when connecting batteries or power supplies to avoid damage. The battery terminal polarity is indicated on the device.
- Use appropriate gauge wires for higher amperage tests to prevent overheating of cables.

Nastavení a připojení
Follow these steps to set up your Electronic Load Tester:
- Napájení zařízení: Connect the tester to a DC6-12V power source using either the DC5.0 power supply port or the Micro USB power supply port.
- Initial Current Adjustment: Before connecting any battery or power supply for testing, ensure both the coarse and fine current adjustment knobs are turned fully counter-clockwise to their minimum (zero) position. This is crucial to prevent sudden high current draw.
- Připojení zátěže:
- For batteries or DC power supplies, use the provided alligator clips. Connect the positive (+) terminal of the battery/supply to the positive input of the tester and the negative (-) terminal to the negative input.
- For USB devices (e.g., power banks, chargers), use the appropriate USB input port (USB, Mini USB, Micro USB, Type-C USB).
- Slowly Adjust Current: Once the load is connected, slowly turn the current adjustment knobs clockwise to increase the discharge current to your desired level. Observe the display for real-time current and power readings.
Operace
The Electronic Load Tester offers various measurement and testing capabilities:
Rozsahy měření:
- svtage Měření: 0.00V ~ 200V
- Aktuální měření: 0.00 A ~ 20 A.
- Měření výkonu: 0000.00W ~ 150W (P = U x I)
Napřample, at 10V input, approximately 18A discharge current is possible. At 20V input, approximately 9A; at 30V input, approximately 6A.
Keystroke Operations:
The multi-function button allows for various settings and data resets:
- Dlouhé stisknutí: Resets all data (mAh, Wh, time).
- Dvojitým stisknutím tlačítka: Resets capacity data (mAh).
- Trojitý stisk: Resets power data (Wh).
- Four Presses: Resets time data (00:00:00).
- Five Presses: Toggles auto standby and discharge countdown.
- Seven Presses (No Load): With no load connected, performs current zero calibration and environmental temperature accurate calibration.
Setting Alarm Thresholds:
The device can be configured with various alarm settings to protect the connected device and the tester itself. These settings are typically adjusted using the multi-function button with specific click patterns (e.g., three-click for decrement, double-click for increment) to navigate and set values.
- Přepětítage Varování: Default 300V. Adjustable range 1-300V. If input voltage exceeds this, an alarm sounds.
- Nízký objemtage Varování: Default 0.00V. Adjustable range 0.00-290V. If input voltage drops below this, an alarm sounds.
- Overcurrent Warning: Default 100A. Adjustable range 0.2-150A. If input current exceeds this, an alarm sounds.
- Power Overload Warning: Default 185W. Adjustable range 1.00W-150A. If input power exceeds this, an alarm sounds.
