[QUOTE="greybeard, post: 1777088, member: 18945"] [URL]https://fieldguardian.com/collections/charger-accessories-new/products/field-guardian-digital-fault-finder-joule-meter?variant=35231322603679[/URL] They are $99.95 now. btw, joules cannot be directly measured like amps and volts can be. Joules is a measure of energy and must be calculated mathematically using a measure of volts, coulombs and time. The unit in question uses a 200 ohm resistor to get the measured voltage down to an easily worked value then uses a little microprocessor (tiny computer) to convert the readings to coulombs, then to joules. It has to have the resistor to drop the extremely high voltage down to prevent burning up the electronic components on the microprocessor.
