o erating the meter.
•Kee the manual at hand so as to enable quick reference when necessary.
•Ensure that the use of the meter is in its intended a lications and follow measurement
rocedures described in this manual.
•Follow all safety and o erating instructions to ensure maximum ersonal safety during the use and
o eration to the meter.
•Fallure to follow the above instructions may cause injury, instrument damage and/or damage to
equi ment under test.

DANGER is reserved for conditions and actions that are likely to cause serious or
fatal injury.
WARNING is reserved for conditions and actions that are likely to cause serious
or fatal injury.
CAUTION is reserved for conditions and actions that are likely to cause minor
injury.
DANGER :
•Never use the meter to measure voltages on a circuit above the maximum allowable in ut value
on any function.
•Do not exceed the maximum allowable in ut of any measurement range.
•Never touch ex osed wiring connections or any live circuit when attem ting to take
measurements.
•Do not attem t to make measurements in flammable gaseous areas, fumes, va or or dust. The use
of the instrument in these areas may cause s arking, which can lead to an ex losion.
•Do not attem t to use the instrument if its surface or your hand is wet.
•Never o en the battery com artment cover when making measurements.
WARNING:
•Always ins ect the meter and test Leeds for any signs of damage or abnormality before use. If the
meter or its accessories have any structural defects such as broken test leads, cracked cases,
ex osed metal arts or the dis lay is not reading do not attem t to make measurements.
•Do not turn the function switch whilst test leads are connected to the meter.
•Do not install substitute arts or make modifications to the meter. Return the meter to your
distributor for re air or re-calibration.
•Ensure the meter is switch off before o ening the battery cover when re lacing the battery.
•Never re lace a battery in the surface of the meter is wet or moist.
5
CAUTION:
•Before making measurements ensure that the function selector switch is set on the a ro riate
range osition
•Always make sure that the lug of each test lead is inserted fully into the a ro riate terminal of
the meter.
•Ensure that the function selector switch is set to the “OFF” osition after use. When the meter
will not be in use for a long eriod of time, lace it in storage after removing the battery.
•Do not ex ose the meter to direct sunlight, extreme tem eratures or moisture.
•Do not use abrasives or solvents on the meter. To clean it use a dam cloth and mild detergent
only.
Qualified and trained service technicians should only erform calibrations and re air of the meter.

6. DC CURRENT MEASUREMENT
WARNING: Ensure that the test Leeds are disconnected from the meter before making
current measurements.
1. Set the function switch to or or range osition, and make sure that the
current under test does not exceed the u er limit of the measuring range you hale selected.
The meter automatically defaults to DC Current.
2. Press the button once the sign will a ear on the LCD indicating Rang is zero.
3. Press the trigger to o en u the transformer jaws and clam around the single conductor under
test.
4. Read the dis lay.
No e:
•During current measurements kee the transformer jaws fully closed, otherwise this affect the
accuracy of the measurement.
•When large current the transformer jaws may buzz. This is not a fault and does not affect the
accuracy of the reading.

7. AC TRUE RMS CURRENT MEASUREMENT
WARNING: Ensure that the test leads are disconnected from the meter before making
current measurements.
1. Set the function switch to or or range osition, and make sure that the
current under test does not exceed the u er limit of the measuring range you hale selected.
2. Press the button to select the AC Current range. The meter automatically defaults to DC
Current.
3. Press the trigger to o en u the transformer jaws and clam around the single conductor under
test.
4. Read the dis lay.
No e:
•During current measurements kee the transformer jaws fully closed, otherwise this will affect
the accuracy of the measurement.
•When large currents the transformer jaws may buzz. This is not a fault and does not affect the
accuracy of default to “Auto Range” mode.
•The meter is set hold button will allow the user to record the eak maximum and
minimum Reading on the AC volt range. See age 19 for further instructions for “PEAK” Hold
function.
