Safety information
This meter has been designed according to EN61010-1,
EN61010-2-030,EN61010-2-033,EN61010-2-031, 600V
CAT II, 300V CAT III and pollution2.
Follow all safety and operating instructions to ensure the
meter is used safely and is kept in good condition With
proper use and care, your digital multimeter will give you
years of satisfactory service.
During use
• Never exceed the protection limit indicated in the
specifications for each range of measurement.
• Never use the meter to measure voltages that might
exceed 600V above earth ground in category II
installations
• Always be careful when working with voltages above
60v dc or 30v ac rms. keep fingers behind the probe
barriers while measuring.
• Do not perform resistance measurements on live circuits.
• Inspect test leads and probes for cracks, breaks or
crazes in the insulation before using the meter.
•
If the equipment is used in a manner not specified by
manufacturer, the protection provided by equipment may
be impaired.
