LEAK SEEKER |
|
| -> Description of Leak Seeker. Wouldn't it be great if leaky or shorted parts just lit up and whistles at you? Well, guess what ... The Leak Seeker 82 from EDS can guide you to the right culprit with whistles and flashing lights! Shorted or leaky components in a circuit can be difficult to locate because your ohmmeter will show the same shorted or low reading at every pad along the suspected trace. You've probably wished for a better way to find these defective parts in-circuit, rather than cutting up the trace into segments and unsoldering and checking every suspicious part in each segment. Sure, you can use an expensive 6 digit DVM with a milliohm range and compare readings at different pads, looking for the pad with the lowest reading. This is time consuming and only works for dead-shorted components, because the meter's resolution isn't high enough for values beyond a few ohms. Also, you would have to keep remembering and comparing all of the readings. Also, no DVM will even register on an active short because their test voltages aren't high enough. Ever had a shorted vertical chip on the other side of a diode? Notice that the DVM won't show the short in the 24 volt power supply because it won't bias the diode forward.EDS has the better mousetrap. |

Simply touch Leak Seeker's gold-plated probe on any solder pad along the suspicious trace and Leak Seeker automatically calibrates itself to the resistance of the defect, within a 24 milliohm "window". Because the test voltage is a current-limited eight volts, it will power through good diodes to activate shorted components beyond. Touch a pad in one direction or the other and Leak Seeker beeps higher or lower and lights the LED distance scale to indicate that you're getting closer or further from the defect. The 24 milliohm window allows about 2 to 3 inches of PCB trace to be checked, then automatically re-calibrates itself to a new window as you get closer to the short.
Because Leak Seeker has a range of zero to 150 ohms, it can locate not just shorted, but leaky parts as well. And unlike your DVM, Leak Seeker's unique "floating reference" circuitry doesn't give up resolution at these higher leakage values. Once you're in the general area of the defect, switch from the AUTO to the LOCK position, high resolution mode. This locks the "window" and increases resolution to one milliohm, so you can pinpoint the location of the defect within a quarter of an inch. The currently available LeakSeeker 82B has indicators for AUTO and LOCK.
The solder pad where the beep is highest is the location of the defect!
There is also a special 3-wire test mode that isolates Leak Seeker's precision power source from the test circuitry to locate thermally defective leaky components, even when a large electrolytic tries to muddy up your readings. Imagine a piece of test equipment that can find a leaky or shorted component only a quarter of an inch from a good one, both soldered to the same trace, and you have a good idea how much time Leak Seeker can save you.
Leak Seeker comes with a special set of gold-plated test clips and probes, a complete manual with a hands-on tutorial.
Comes with 3 years limited warranty.
