Thank you for purchasing a Model 405 Clamp-on Meter.
For best results from your instrument and for your safety, read the enclosed
operating instructions carefully and comply with the precautions for use. These
products must be only used by qualified and trained users.
Meanings of the symbols used on the device
CAUTION - Risk of Danger! Indicates a WARNING and that the operator
must refer to the user manual for instructions before operating the
instrument in all cases where this symbol is marked.
Risk of electric shock. The voltage at the parts marked with this symbol may
be dangerous.
Refers to a type A current sensor. This symbol signifies that application
around and removal from HAZARDOUS LIVE conductors is permitted.

PRECAUTIONS FOR USE
This device complies with safety standards IEC-61010-1 and 61010-2-032 for
voltages of 1000V in category IV at an altitude of less than 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.

MEASUREMENT CATEGORIES
Definitions of the measurement categories:
CAT IV: Circuits supplying the low-voltage installation of the building.
Example: power lines, meters, and protection devices.
CAT III: Power supply circuits in the installation of the building.
Example: distribution panel, circuit-breakers, fixed industrial machines or
devices.
CAT II: Circuits directly connected to the low-voltage installation.
Example: power supply to household electrical appliances and portable tools.
RECEIVING YOUR SHIPMENT
Upon receiving your shipment, make sure that the contents are consistent with the
packing list. Notify your distributor of any missing items. If the equipment appears
to be damaged, file a claim immediately with the carrier and notify your distributor
at once, giving a detailed description of any damage. Save the damaged packing
container to substantiate your claim.
