FAQ

Can the fluke317 clamp meter test DC current?
Clamp meter is composed of a current transformer and current meter assembly. The iron core of the current transformer can be opened when the wrench is tightened; the wire through which the current is measured can be cut through the opening of the iron core without cutting off, and when the wrench is released, the iron core is closed. Through the test circuit of the core, the wire becomes the primary coil of the current transformer, in which the current is induced in the two coil through the current. A current meter connected with the two coil is then instructed to measure the current of the line being measured. A table can shift through the switch, the scale change.
How much can the current clamp measure up to? How much accuracy can be achieved?
The clamp meter maximum gear 1000A. Resolution 0.1A; accuracy + 2.5%+5. For example, the uni-t.
A fire was found with a ground electricity? Stealing electricity.
Don't do it, it's a question of morality. Abide by social morality, firmly do those unscrupulous things
The power consumption of the same load, different power motors?
The current may be a little smaller, because the power consumption of the motor will be smaller in every respect. Both active and reactive power will be smaller.
Can you direct the direct current with the pliers jaw (not measuring pen)?
A table can only be induced to AC, DC can not be measured. Measuring DC with a multimeter
How to test the current on a motor?
String into the pointer ammeter to see the impact value of the pointer (not very accurate)
Methods use a table clamp type table and the matters needing attention
The observation time, we must pay special attention to keep a safe distance from the head and charged part of the human body and any part of the charged body distance shall not be less than the entire length of the clamp meter.
The current transformer and the ammeter do not show the same
Is the pointer of the ammeter clear? As you described, the flow ratio at one time should be 160:1, one 87A, and the current number is 0.54A
