Definition of Measurement Categories (CAT)
CAT IV Corresponds to measurements taken at the source of low-voltage
installations.
Example: power feeders, counters and protection devices.
CAT III Corresponds to measurements on building installations.
Example: distribution panel, circuit-breakers, machines or fixed industrial
devices.
CAT II Corresponds to measurements taken on circuits directly connected to
low-voltageinstallations.
Example: power supply to domestic electrical appliances and portable tools.

PRECAUTIONS FOR USE
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.

2 OPERATION
2.1 Battery Installation
Before changing batteries: set the switch to OFF, disconnect the
measuring leads,and remove the clamp from the circuit under
measurement.
1. Using a screwdriver, remove the battery compartment cover from the
back of the housing (see Figure 4).
2. Insert the two supplied 1.5V AA batteries, observing polarities.
3. Replace the battery compartment cover and screw it onto the housing.
Figure 4
2.2 Instrument Check
Start the meter by turning the rotary switch to any setting other than OFF.
Observe the LCD and ensure all segments are displayed (see Figure 2).
Turn the switch to the (continuity) setting. The LCD should display
OL.
Connect the two test leads to the instrument and touch the tips together. The
short-circuit buzzer should sound.
Turn the switch to a voltage setting (either or ) and check a known
voltage (for example a battery). Ensure the displayed voltage reading is
correct.
If all previous steps function normally, the meter is ready for operation.
