PRECAUTIONS FOR USE
This instrument complies with safety standards IEC-61010-1 and 61010-2-032
for voltages of 1000V in category IV at an altitude of less than 6500’ (2000m),
indoors, with a degree of pollution not exceeding 2. These safety instructions are
intended to ensure the safety of persons and proper operation of the device.
The operator and/or the responsible authority must carefully read and clearly
understand the various precautions to be taken in use.
If this instrument is used other than as specified, the protection it provides
may be compromised, thereby endangering you.
Do not use the instrument in an explosive atmosphere or in the presence of
flammable gases or fumes.
Do not use the instrument on networks of which the voltage or category
exceeds those mentioned.
Do not exceed the rated maximum voltages and currents between terminals
or with respect to earth.
Do not use the instrument if it appears to be damaged, incomplete, or not
properly closed.
Before each use, check the condition of the insulation on the leads, housing,
and accessories. Any element of which the insulation is deteriorated (even
partially) must be set aside for repair or scrapped.
Use leads and accessories rated for voltages and categories at least equal
to those of the instrument. If not, an accessory of a lower category lowers
the category of the combined Clamp + accessory to that of the accessory.
Observe the environmental conditions of use.
Do not modify the instrument and only use factory replacement parts.
Repairs and adjustments must be done by approved qualified personnel.
Replace the batteries as soon as the symbol appears on the display of
the unit. Disconnect all leads before opening the battery compartment cover.
Use personal protective equipment when conditions require.
Keep your hands away from the unused terminals of the instrument.
When handling the test probes, alligator clips, and clamp ammeters, keep
your fingers behind the physical guard.
As a safety measure, and to avoid repeated overloads on the inputs of the
device, configuration operations should only be performed when the device
is disconnected from all dangerous voltages.
