CAUTION! LEAKAGE CURRENT TESTING IS INHERENTLY HAZARDOUS
RISK OF ELECTRIC SHOCK – KEEP HANDS AND FINGERS AWAY FROM ENERGIZED
COMPONENTS AT ALL TIMES
NO USER SERICEABLE PARTS INSIDE – SERVICING BY QUALIFIED SERVICE
PERSONNEL ONLY!
Product purpose:
The LT-952 leakage current tester is a state-of-the-art test instrument designed to measure leakage current
in accordance with major standards, such as 60950, 60335, 6500, 61010, and others based on IEC 60990.
The LT-952 is designed to make leakage current testing easy. Gone is the jumble of wires necessary to
simulate the prescribed test conditions. No more searching for an adequate meter to use. No more worries
about calibration or correlation with the testing agencies. The LT-952 transforms what was once a one-hour
procedure into a quick and simple test.
Features that make the LT-952 easy to use include:
Built-in 3 1/2-digit LCD meter that measures the true RMS value of leakage current. True RMS is
especially important in products where the leakage current is non-sinusoidal as is possible with switch-
mode power supplies and products that use them.
