Safety Information
The DM II Plus conform to EN61010-1:2001; EN61010- 2-032:2002; CAT III 600 V, Insulation
•
Class II and pollution deg. 2. and EN 61557-7.
This instrument is EN61010-1 certified for Installation Category III (600V). It is
•
recommended for use in distribution level and fixed installations, as well as lesser
installations, 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 V ac rms between
phase to phase or 370 Vac phase to earth ground.
Warnings and Precautions
Before and after hazardous voltage measurements, test the voltage function on a
•
known source such as line voltage to determine proper meter functioning.
Inspect the meter, clamps, test leads and accessories before every use. Do not use any
•
damaged part.
Never ground yourself when taking measurements. Do not touch exposed circuit
•
elements 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 moisture.
•
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, 42.4 Vpk, or 30
VAC rms. These voltage levels pose a potential shock hazard to the user.
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 measurement.
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 current sensor is designed to apply around or remove from un-insulated
•
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 power
•
line with inductive loads // AC power line during electrical storms // current, when the
fuse blows in a circuit with open circuit voltage >1000 V // servicing CRT equipment.
Remove all test leads before opening the case to change the battery.
•
To avoid false readings, which could lead to possible electric shock or personal injury,
•
replace the batteries when the low battery indicator
appears.
To avoid electric shock hazard, do not use the HOLD mode to determine if a circuit is live.
•
Unstable readings will not be captured and displayed.
For accurate measurements after long-term storage in severe environmental conditions,
•
wait until the instrument returns to its normal operating conditions.
