Using Electrical Test Equipment - DVD

$ 195.00


A multimeter is an instrument that measures electrical properties such as voltage, current, and resistance. In substations, multimeters are commonly used for testing circuits, making adjustments. This 61-minute DVD explains the purpose and operation of voltage testers, multimeters, clamp-on ammeters, and megohmmeters to measure current, voltage, and resistance. Safety precautions are emphasized throughout. It demonstrates how to perform voltage, current, and resistance measurements using the test equipment discussed.

Training Sessions

Using a Voltage Tester – 8 minutes
States the main purpose of a voltage tester. Names the parts of a voltage tester and explains how a voltage tester works. Lists the steps required to check out a voltage tester and explains why it is necessary to check out a voltage tester before each use. Shows how to use a voltage tester.

Meter Principles – 9 minutes

Lists the two general ways in which meters are classified. Describes the functions of a multimeter, a clamp-on ammeter, and a megohmmeter. Explains how a permanent magnet moving coil (PMMC) meter movement works. Shows how a current measuring device can also be used to measure voltage and resistance.

Using a Multimeter, Part 1 – 12 minutes
