GSafety Information
Understand and follow the operating instructions carefully.
GWARNING
Identify hazardous conditions and actions that could cause BODILY HARM or DEATH
When using test leads or probes, keep your fingers behind the finger guards.
Personal protective equipment should be used if there are ACCESSIBLE
HAZARDOUS LIVE PARTS in the installation where measurement is to be carried
out.
Remove test leads from meter before opening the battery door or meter case.
Use the meter only as specified in this manual; otherwise, the protection provided
by the meter may be impaired.
Always use the proper input terminals, switch position, and range for
measurements.
Verify the meters operation by measuring a known voltage. If in doubt, have the
meter calibrated.
Do not apply more than the rated voltage, as marked on the meter, between
terminals or between any terminal and earth.
Use caution with voltages above 30 V AC rms, 42 V AC peak, or 60 V DC. These
voltages pose a shock hazard.
To avoid false readings that can lead to electric shock and injury, replace the
battery as soon as the low battery indicator blinks.
Disconnect circuit power and discharge all high-voltage capacitors before testing
resistance, continuity, diodes, or capacitance.
Do not use the meter around explosive gas or vapour.
To reduce the risk of fire or electric shock do not expose this product to rain or
moisture.
PVHV test leads are only for use on circuits NOT directly connected to a MAINS
supply.
Probe assemblies to be used for MAINS measurements shall be RATED as
appropriate for MEASUREMENT CATEGORY III or IV according to EN 61010-
031 and shall have a voltage RATING of at least the voltage of the circuit to be
measured.

GSafety Information
■DO NOT USE the test leads if the internal white insulation layer is exposed.
■DO NOT USE the test leads above maximum ratings of CAT Environment or
voltage and current that are indicated on the probe and probe tip guard.
■Do not apply a current with a frequency that is higher than the frequency
response range speci󰘰ed in the Electrical Speci󰘰cations section.
■Do not apply or remove the clamp or test leads on or around uninsulated
hazardous live conductors where a potential to cause electric shock, electrical
burns or arc 󰘱ash exists.
GCAUTION
Disconnect the test leads from the test points before changing the position of the
function rotary switch.
Never connect a source of voltage with the function rotary switch in Ω, and
position.
Do not expose the meter to extremes of temperature or high humidity.

Making Basic Measurements
Preparation and Caution Before Measurement
GObserve the rules of GWarnings and GCautions.
GCAUTION
When connecting the test leads to the DUT (Device Under Test) connect the common test
lead before connecting the live test lead. When removing the test leads remove the live
test lead before removing the common test lead.
Measuring Voltage
Turn the switch to select the measuring function.

Measuring PV Voltage
Turn the switch and press the Function button to select AC/DC mode
GCAUTION
This function is only available with the dedicated PVHV test lead sets.
For CAT III or CAT IV environments: use the test leads with the probe tip guard cap fixed
firmly. Without the probe tip guard cap, the test leads can be used in CAT II environments
ONLY.
For 1500 V AC and 2000 V DC measurement (CAT 0): these test leads can only be used in
environments that are not directly connected to the MAINS supply.
Always select correct AC/DC mode to perform any high voltage measurement.
The meter will flash this symbol Fand the correct mode symbol (AC/DC) if the input
voltage is different and/or dangerous.
