Annual Calibration

Like most test equipment, it is important for ACT Intelligent Battery Testers to be calibrated to maintain accuracy. We recommend calibration to be carried out every 12 months.
There are two options to calibrate your ACT Intelligent Battery Tester. The first option is to purchase an ACT CALKIT. This enables your battery tester to be calibrated inhouse, quickly and easily. Each kit comprises of new, calibrated test leads and replacement labels. Please view our CALKITS and purchase from a local distributor.

The second option is to have your battery tester sent to the approved calibration laboratory.
