| A new Lame Tester
I have designed and built a Lame testing system. It has two parts. The first is the probe. It consists of a 500 gram weight that is inside a PVC tube. It slides up and down and is connected to a brass rod that ends in an 8mm brass ball. You hold it in a vertical position and move it over the lame, getting 500 grams pressure on the 8mm ball.
The probe and the lame are connected to the display unit. This is shaped like a conventional digital voltmeter and is powered by two AA cells. It has a digital display, very similar to other voltmeters, and an LED bargraph. The bargraph display is ten LEDs that change in color from green to yellow to red, from left to right. Each LED represents one ohm.
As the probe passes over the lame, the bargraph quickly displays the resistance rise and fall, much like an analog meter. Watching the bargraph, the technician can quickly see the resistance changes. At ten ohms, all the LEDs are on. The digital display is a 0 to 100 ohm meter. The probe can be held in one place, like an area that lights all the LEDs, and the resistance in ohms is displayed.
I like to design and build fencing test equipment. The next step is to throw it in a box, with all the other things I designed, or make and sell some. Is anyone interested in this Lame test set?
