Introduction
The ACD-14 PLUS and ACD-14 TRMS-PLUS are digital clampmeters that measure both AC
and DC voltage, AC current, Resistance, Frequency, Continuity and Diode Test. Frequency
can be measured in the voltage and current modes.
WARNINGS AND PRECAUTIONS
Safety Information
• The ACD-14 PLUS Series Digital Clampmeters conform to EN61010-1:2001; EN61010-
2-032:2002; CAT III 600 V, class 2 and pollution deg.2
• This instrument is EN61010-1 certified for Installation Category III (600V). It is recom-
mended for use in distribution level and fixed installations, as well as lesser installa-
tions, and not for primary supply lines, overhead lines and cable systems.
• Do not exceed the maximum overload limits per function (see specifications) nor the
limits marked on the instrument itself. Never apply more than 600 Vdc/600 V ac rms
between the test lead and earth ground.

WARNING
• Before and after hazardous voltage measurements, test the voltage function on a
known source such as line voltage to determine proper meter functioning.
• Disconnect the test leads from the test points before changing meter functions.
• Inspect the Clampmeter, test leads and accessories before every use. Do not use any
damaged part.
• Never ground yourself when taking measurements. Do not touch exposed circuit ele-
ments or test probe tips.
• Do not operate the instrument in an explosive atmosphere.
• To reduce the risk of fire or electric shock, do not expose this product to rain or moi-
sture.
• The meter is intended only for indoor use. To avoid electrical shock hazard, observe
the proper safety precautions when working with voltages above 60 VDC or 30 VAC
rms. These voltage levels pose a potential shock hazard to the user.
• Before and after hazardous voltage measurements, test the voltage function on a
known source such as line voltage to determine proper meter functioning.
• Keep your hands/fingers behind the hand/finger barriers (of the meter and the test
leads) that indicate the limits of safe access of the hand-held part during measure-
ment.
• Inspect test leads, connectors, and probes for damaged insulation or exposed metal
before using the instrument. If any defects are found, replace them immediately.
• This Clamp-on meter is designed to apply around or remove from uninsulated
hazardous live conductors. Individual protective equipment must be used if
hazardous live parts of the installation could be accessible.
• Exercise extreme caution when: measuring voltage >20 V // current >10 mA // AC
