About this product

Overview

Product overview

• Can be used to detect continuity and therefore for checking fuses or lamps
• Other uses include short circuit tests, tracking broken cables, microwave oven radiation testing and television emission tests.
• Supplied with batteries (battery life of approximately 5 hours continuous use)
• Dimensions 136 x 20mm including clip

Continuity tests can be made by holding the tip of the screwdriver on a fuse then touching the cap of the screwdriver and the cap of the fuse with your hand. If the fuse is OK, the screwdriver will light. The same principle can be used with lamps, leads and anything else that is conductive.
NB Not suitable for direct connection with live circuitry.

Rated 4 out of 5 by from Clever device Good for checking continuity but can sometimes give a false result due to current short circuiting between the hand holding the plastic part and the tip or contact at the top. Hands and the tool have to be perfectly dry to give reliable signals.

Rated 4 out of 5 by from Not just a continuity tester Described on packing as All Purpose Voltage Tester. I used these devices for many years in my electrical maintenance job and found them extremely useful. Lost one, broke the blade on another trying to undo an extremely tight screw and my third the contacts inside became corroded due to getting it waterlogged. Missed it so have bought myself a new one. Highly recommend this device for quick indications and the blade is ideal for most terminal screws

As you are part of the circuit when testing continuity this is not advised.

Is this the same as a circuit tester? - i.e. can I use it to test whether or not a lamp is broken or the bulb just needs replacing?
Asked by: Frank B
Yes the product does support that.
