How does it work

The Megger Torkel 820 works by discharging batteries under controlled conditions to test their capacity and performance. Here's how it operates:

1. Setup: At the start of the test, you enter the number of battery cells. The device then sets voltage warnings and stop limits automatically or manually.

2. Voltage Limits:
- You can set a warning voltage per cell (e.g., 1.85 V/cell).
- You can also set a stop voltage per cell (e.g., 1.80 V/cell).
- The device issues warnings or stops discharging when these limits are reached.

3. Time and Capacity Limits:
- You can set warnings or stops based on time elapsed (e.g., 50% or 100%).
- You can also set warnings or stops based on discharged capacity (e.g., 50% or 100%).

4. Measurement:
- A clamp-on ammeter must be used with the arrow pointing in the direction of current flow.
- Current measurement must be set to “External,” and the mV/A ratio must match the ammeter.

5. Alarm Function:
- The alarm activates if Torkel is off or if there's no mains voltage.
- An external alarm can be connected.

6. Software:
- TORKEL Win software can be used for reporting, copying voltage curves, and changing settings.
- A software key is needed for full functionality but the program can be evaluated without it.

In summary, the Torkel 820 performs battery discharge tests by monitoring voltage, time, and capacity, issuing warnings or stopping as configured, and can be integrated with external measurement and alarm systems.
