• Stepping motor test function for rapid battery testing without disassembly
• Independent battery and watch testing functions ensure accurate results

Specifications

• Measuring range: 1.55 V to 3 V
• Stepping motor test function for quick checks without disassembly
• CR2430 lithium battery included (replaceable)

Battery Testing Instructions

To ensure accurate results, follow these steps:

1. Select the battery type using the switch at the right of the device. The Silver 1.55 V position is also suitable for alkaline/manganese button cells.
2. Place the battery plus side down on the testing point and press the contact spring against the negative battery side.
3. The pointer of the measuring instrument should be within the green dial area.
4. If the needle fails to reach the green area, the battery is discharged and needs to be replaced.

General Information

Important notes:

1. Battery and watch testing functions are independent of each other. You may check a watch and test batteries at the same time.
2. Battery testing requires no internal battery power, making it possible to perform even if the tester’s CR2430 lithium battery has run out.
3. Avoid close proximity to strong magnetic fields generated by computer monitors, electronic motors, etc. to prevent incorrect “Watch Test” results.
