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.
Prevents careless mistakes
qAuto-power off to conserve battery life qNon-fuse type protects up to 600V AC

! 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. !
Even if voltage is mistakenly applied to the resistance range, the internal excessive voltage protection element ( PTC thermister) protects the circuits for up to 600 V AC. (optional)
9462 THERMISTER TEMPERATURE PROBE
q Measuring range:-50 to 150˚C/-58 to 302˚Fq Measuring accuracy: -50 to 50 ˚C±3˚C/50 to 100˚C±4˚C/100 to 150˚C±5˚C Note: the temperature accuracy given above is only the accuracy for the temperature probe. ±2%rdg.±2˚C(˚F) is added for the actual accuracy of the 3281/3282 themselves.
Cord length approx 1.2 m
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.
