True battery resistance tester that applies a resistance load that duplicates starting load conditions.
Resistance load is auto-timed for increased accuracy.
Unique test and hold feature locks the under load voltage reading for easy comparison to the pass/fail test matrix.
Maximum starting resistance load: up to 400 CCA, 0-15V.
Can also be used to test starter draw and charging system voltage using the open-circuit voltage meter function with the high-low-normal voltage matrix on the tester face.
Includes safety reverse polarity indication.
Built-in wall hanger.
