At present, our largest high voltage tester, the CH+, is limited to 5,376 points.   The new CH2 offers 20,000 points, with even more point capability to come later.   CH2 scanner boxes don't need to be in one spot either.   Distributed testing means that you can place scanners up to 200 ft apart to minimize the length of fixture cabling to large devices under test such as aircraft.   The software operating the CH2 is the same easy-wire software available on the CH+ and the CR.   To learn more about the CH2 see our short video at:

The new easy-wire CH2. Hipot Testing Made Easy.

Do you have wire on spools or in drums of unknown length?   Knowing the actual length is important when making an inventory count or checking to see if you have enough wire to complete an order.   For smaller spools you can estimate length using a count-scale, measuring a sample length of wire, then weighing the whole spool.   You must have an equivalent empty spool to know the tare weight that needs to be deducted for an accurate count, but you can get a good guesstimate this way.

For multi-conductor cable, and especially coax cable, the Harris TS100 Cable Fault Finder can measure distance to end of cable.   Just google "Harris TS100" for more information on this product.   It costs about $350.   You do need to set a correct propagation velocity, which requires you to measure a known length of the equivalent kind of wire.

The low-cost solution is to simply measure the resistance of the wire with a volt-ohm-meter (VOM) and, based on gauge, calculate the length.   This solution works on single conductor cable too.   We have added a wire length calculator to the many tools available on our website at:
