Actual-size Designed for ease of use on the site ! The HAND STRAP fits the device neatly to the hand The HAND STRAP not only prevents the device from being dropped when working, but also effectively imparts strength when parting crowded wiring to clamp. The photograph is 3281. Prevents careless mistakes ●Auto-power off to conserve battery life ●Non-fuse type protects up to 600V AC NOT SE FU NEEDED ! WARNING Inspect the unit and check that it is operating correctly before use. When carrying out measurement on live lines, wear proper protective gear, insulating rubber gloves, insulating rubber boots and safety helmet, and use extreme caution to avoid electric shock accidents. ! DANGER 1. In order to prevent short-circuits and injury, use the clamp product on electrical circuits with a voltage less than the maximum operation circuit voltage. 2. In order to prevent short-circuits and injury when the clamp core tip is open, do not use bare conductors. ■ Specifications Function Mode [ ] in the Specification :3281 23˚C±5˚C, 80% or less.
