Has a button for switching between different measurement parameters. The button is also used for resetting the over current count number and the peak current value.
Measurement parameters:
The module displays six main parameters:
1. Output voltage (V)
2. Output current (A)
3. Total runtime (in kilohours/1000 hours, Kh)
4. Remaining service life until replacement (in %)
5. Number of overcurrent occurrences
6. Peak output current (A)
