LCR Meter
A LCR meter (Inductance (L), Capacitance (C), and Resistance (R) is a piece of electronic test equipment used to measure the impedance (inductance, capacitance, resistance) of a component.
*See LCR Meters from QuadTech
Level
The test signal level is the programmed RMS voltage of the generator in an LCR meter. The actual test voltage across the DUT is always less than the programmed level.
Line Leakage
The residual flow of current through insulation after a high voltage has been applied.

Line Regulation
Refers to the ability of a power supply to regulate and maintain the ouput voltage regardless of varying input voltage.

Load
The total resistance or impedance of all circuits and devices connected to a voltage source.
Low Limit
The lower value for a test to be considered a PASS. If the measured value is lower than the low limit the test is considered a FAIL. In insulation resistance mode a low limit is required.

Medical Safety Analyzer
Electrical safety analyzers are used to test medical devices and instruments to be used in the medical industry. Medical safety analyzers can perform electrical safety tests, continuity measurements, IEC 60601-1 and 60601-2 testing, and other tests. <<br> See: Medical Device Testing Systems

Ohm (Ω)
The unit of measure of resistance and impedance, derived from Ohm's Law.
Ohmmeter / Micro-ohmmeter / Megohmmeter
A meter that measure electrical resistance
Ohm's Law
The fundamental law of electrical circuits describes the relationship between voltage, current and impedance (or resistance). For DC circuits, Ohm's Law states that Current =Voltage/Resistance. For AC circuits, Current = Voltage/Impedance. Stated conversely, Voltage = Current x Resistance (DC) or Current x Impedance (AC). The difference between the DC resistance and AC impedance is that AC circuits must deal with phase and time relationships and DC circuits do not.
