The Fluke 337 is a clamp meter. It can be purchased directly from Fluke. MCM Electronics is also an authorized dealer for Fluke products, as is MAT Electronics.
A fluke meter measures Capacitance. It also measures frequency. They also have multi meters. Some are capable of measuring the capacitance and some are not. Usually the more expensive ones are capable of measuring capacitance.
Use a meter that simultaneously will test for both. Most better meters such as Fluke have this capability Or Switch your meter to AC if you get no voltage over the reading then likely you have a DC circuit. Don't do this by switching to DC first, You very well will ruin your meter if your meter does not have protection to handle this.
A Fluke 123 meter can be purchased from many electrical stores, such as Farnell. Alternatively, one can purchase this item from webpages stores such as Amazon or Ebay.
Fluke Test Leads can be purchased at online retailers including Grainger, Test Path, and TransCat. This product can also be purchased at Amazon and eBay.
Multiplication factor can be derived from Meter CT, Meter PT, Connected CT and Connected PT values.
mf is ratio of CT ration of meter box to CT ration written on meter. ex: CT meter box: 30/5, Meter ct ration 1/1. MF : (30/5)/(1/1)= 6
long travelling and cross travelling meter
ct ratio test is the current between the primary to secondary
multiplying factor = Line CT Ratio / Meter CT Ratio Usually it is mentioned on Meter that MF = 1 if CT Ratio is 200/5 or MF = 2 if CT Ratio is 400/5. There can be an additional multiplication factor that would be mentioned on the meter.
