Peak Detect Acquisitions Time: Approx. 100ms.
(Acquisition time is the minimum duration of a surge for rated accuracy. Accuracy improves for longer peak duration).

SAFETY RULES

1. Never ground yourself when taking electrical measurements. Keep your body isolated from ground by using dry
clothing, rubber shoes, rubber mats or any suitable and approved insulating material.
2. Disconnect input signal before touching the battery.
