1. Disconnect battery tester/test equipment.
2. Observe basic setting of the volt-amp(s) tester (1), if necessary adjust the knob (3) to 16 V and knob (4) to 50 A.
3. Clip load pliers (5) onto the battery.
4. Connect terminals (7) to corresponding load clamps (5).
5. Place current clamp (6) around positive line of battery.

Pay attention to current direction. The measurement takes place via an inductive coil in the current clamp (6).

6. Switch on Volt/Amp(s) tester (1) via operating lever (2) and load battery with 20 A to 30 A for approx. 60 s.

The increased voltage is now reduced.
