To test a current transformer (CT) with a Fluke meter, you'll first need to set the meter to the appropriate AC current setting. Connect the meter leads to the secondary terminals of the CT while ensuring the primary circuit is energized safely. Measure the output current; it should reflect the expected ratio based on the CT's specifications. If the reading is significantly different from expected, the CT may be faulty or improperly connected.
Fluke is a very good and very popular test meter.

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.
No, a Fluke meter is not suitable for megger testing, which requires a dedicated insulation resistance tester or megohmmeter. While Fluke meters can measure voltage, current, and resistance, they do not generate the high test voltages needed to assess insulation integrity. For accurate insulation testing of motors, a megger is necessary to apply the appropriate voltage and provide reliable readings.
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
