Electrical Equipment & Testing
Electrical Test Equipment
The equipment required to service these models depends largely upon the condition encountered. Locating a malfunction will often require the use of electrical testing equipment such as:
Appliance Test Meter
Motor Test Cord
Digital Test Meter
can be used to check for open or closed circuits, measure resistance, AC and DC volts, and temperature.
Appliance Test Meter
An Appliance Test Meter is a
The easiest means of testing electrical components is "Continuity Testing" with an appliance meter. Continuity is a complete or continuous path from one point in an electrical circuit to another.
The obvious advantages of being able to check electrical components and circuits without power applied is one of the features of the Ohmmeter. Multiple ranges allow accurate determination of resistances of both single components and entire circuit paths. Resistance is measured in "Ohms."
!WARNING
Analog Test Meter
can be used to check for open or closed circuits, measure resistance, AC and DC volts, and temperature.
To avoid risk of personal injury or death due to electrical shock:
Always be sure the power has been disconnected before making resistance measurements. Failure to do so will also result in damage to your meter! Internal batteries provide all the power needed to make resistance checks. They should be checked at least once a year and replaced as needed.
Continuity Testing: is a process of eliminating electrical components involved in a given function of the appliance, until the inoperative part is found. By reviewing the list of possible electrical problems under a given condition, and then performing appropriate continuity checks of the parts involved, you should be able to locate the electrical component which is inoperative.
NOTE: When checking components or circuit paths for continuity, external wiring should be disconnected to eliminate false readings through external paths. Isolate what you want to test.
