Slat & Cable Tester
This small device is roughly the size of a credit card - but a bit thicker. It uses 2 "AAA" size batteries, mounted on backside. The measured current thru a typical match is less than 10mA. Although well below the 50mA Max test limit, all precautions should be taken. All personnel should be distant from the devices under test.
There are two models - Slat10 Tester for 10 position slats, and Slat12 Tester for 12 position slats. Both are the same price.
