Capacitance testers are mainly used to test the performance and capabilities of capacitors, particularly their capability of holding or storing an electrical charge. It is very important to conduct capacitance testing to detect any leakage in capacitors, which may reduce overall effectiveness of a circuit or lead to electrical breakdown of a device.

Salient Features

• The tester can be either handheld or placed on a tabletop.
• These testers are mostly portable and includes test leads that attach to a circuit to evaluate the quality of a capacitor or condenser.
• Capacitance testers measure different ranges of charge.
• The device may also include a probe, called capacitance probe for testing capacitors in environments where the circuits are difficult to reach with test leads, or where materials being tested are wet or sticky.
• Capacitance probes are generally made of stainless steel with a Teflon or polyethylene coating for insulation.

Uses & Applications of Capacitance Testers

• Used to perform capacitance continuity test.
• Identify when a capacitor is weak or leaking.
• Identify whether a capacitor is open and not storing a charge.
• Signal processing.
• Power supply applications.
• Computer motherboards.
