3.3. Operation (B1T-Magnetic)
- For 1.5V Cylindrical Batteries (AAA, AA, C, D):
- Locate the 1.5V slot on the tester.
- Place the battery between the positive (+) and negative (-) terminals. The magnetic contact will help secure the battery.
- Observe the needle on the gauge.
- For 9V Batteries:
- Locate the two small terminals at the top of the tester.
- Press the 9V battery's terminals against the tester's terminals, ensuring correct polarity.
- Observe the needle on the gauge.
