BA101 Battery Tester Clamping Method Manual

Introduction to Battery Inspection Instrument Clips

The BA101 battery inspection instrument utilizes positive and negative clips, each composed of two contacts that are insulated from each other. For accurate testing, it is crucial to ensure that both contacts are in good, firm contact with the battery terminals and remain insulated from each other.

Proper Clamping Illustration

The battery clips feature two distinct contact points: "contactor 1" (the main jaw) and "contactor 2" (the smaller, inner jaw). When clamped correctly, both contactors should make secure, insulated contact with the battery terminal.

Correct Connection Example

When the BA101 battery tester is correctly connected to a VARTA 12V 55Ah 610A battery, the display typically shows a "GOOD BATTERY" status with readings such as "Healthy", "Charge", and "Internal Resistance". This indicates a proper connection and a healthy battery state.

Incorrect Clamping Scenarios

Improper clamping can lead to inaccurate test results or "Clamp Fault" indications. The following scenarios illustrate common incorrect connections:

Negative Contactor 2 Out of Touch: The smaller, inner jaw of the negative clip is not making proper contact.
Positive Contactor 2 Out of Touch: The smaller, inner jaw of the positive clip is not making proper contact.
Negative Contactor 1 Out of Touch: The main jaw of the negative clip is not making proper contact.
Positive Contactor 1 Out of Touch: The main jaw of the positive clip is not making proper contact.

In all these cases, the ANCEL BA101 battery tester may display "Clamp Fault" or provide erroneous readings.

BA101 Test Results with Different Clamping Methods

The table below summarizes the test results obtained from the BA101 battery tester under various clamping conditions for a 12V 55Ah 610A battery. A "√" indicates a normal connection, while an "X" indicates an abnormal connection or error.

Conclusion

To obtain accurate and reliable test values from the ANCEL BA101 battery inspection instrument, it is imperative to ensure that both the positive and negative clips make good, secure contact with the battery terminals. Any deviation from proper clamping, where one or both contacts are out of touch, will lead to erroneous readings or a "Clamp Fault" indication.
