How do you use a tong tester?

How to Operate Clamp Meter (Tong Tester)

  1. Switch ON Clamp meter (Tong tester).
  2. Only a higher scale-value should be selected in order to avoid any harm to the circuit.
  3. Clip ON ammeter around each cable in turn and measure current.
  4. Keep it in mind that current of only one cable to be measured at one time.

How does a clamp multimeter work?

A clamp meter is a clothespin-shaped instrument that can be clamped around a live wire in order to measure the current it’s carrying. As a measurement principle, clamp meters detect the magnetic field emitted by current flowing in a wire in order to measure the current value.

How do you read the amp on a clamp meter?

To measure ac current using a flexible current probe:

  1. Connect the flexible current probe to the meter.
  2. Connect the probe’s flexible tubing around the conductor.
  3. Keep the probe coupling more than 1 inch (2.5cm) away from the conductor.
  4. Turn the dial to the icon.
  5. View the current value in the display.

What is Tong testing?

A clamp meter is one kind of test equipment and it is also known as Tong Tester. This equipment is very simple to use and operate. The main function of this device is to measure a live conductor in the circuit without damage or power loss.

What is a tong tester used to measure?

An electrical tong tester is also known as clamp meter. It is used to measure current in a circuit in amperes. It can measure large AC currents up to 1000 amperes.

What’s the difference between a multimeter and a clamp meter?

Significant difference between Clamp meter & multimeter: A clamp meter is an ideal option for measuring current, whereas a multimeter is suitable for measuring voltage, resistance, a frequency with better resolution and accuracy.

How do you measure current with a current clamp?

To measure ac current with a current output clamp, turn the dial to mÃ/Ã. Plug the black test lead into the COM jack. For plug-in clamp accessories that produce an ac current output, plug the red test lead into the mÃ/Ã jack.

How do you use a clamp meter to measure resistance?

How to make resistance measurements

  1. Turn off power to the circuit.
  2. Select resistance (Ω).
  3. Plug the black test probe into the COM-input jack.
  4. Connect the probe tips across the component or portion of the circuit for which you want to determine resistance.
  5. View the reading in the meter’s display.
