DO not test Voltage more than 550V
1-2.Safety Information
This meter has been designed for safe use, but must be operated with caution, the rules listed below must be
carefully followed for safe operation.
• Do not carry out any measurement in humid environments.
• Do not carry out any measurements in case gas, explosive materials or flammables are present, or in dusty
environments.
• Avoid any contact with the circuit being measured if no measurements are being carried out.
• Avoid any contact with exposed metal parts, with unused measuring probes, circuits, etc.
• Do not carry out any measurement in case you find anomalies in the instrument such as deformation, breaks,
substance leaks, absence of display on the screen, etc.
• Before each use, verify meter operation by measuring a known voltage.
• Do not use the meter on a circuit with voltages that exceed the category based rating of this meter.
• Do not use the meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear to be damaged.
• Use Only with CAT IV rated test leads.
• Ensure meter leads are fully seated, and keep fingers away from the metal probe contacts when making
measurements.
• Do not open the meter to replace batteries while the probes are connected.
• Use caution when working with voltages above 25V AC RMS or 60V DC, such voltages pose a shock hazard.
• To avoid false readings that can lead to electrical shock, replace batteries when a low battery indicator appears.

True RMS Multimeter & Insulation Tester
• Do not attempt to measure resistance or continuity on a live circuit.
• Make sure the circuit under test does not include components that can be damaged by 1000VDC; such devices
include power factor correction capacitors, low voltage mineral insulated cables, electronic light dimmers, and
ballast/starters for fluorescent lamps.
• Do not perform insulation resistance testing or earth-bond resistance testing if voltage is present on parts of an
installation or equipment under test, circuits under test (except for voltage measurements) must be de-energized
and isolated before connections are made.
• Circuit connections must not be touched during a test, accidental contact with conductors could result in electrical
shock.
• After insulation resistance testing, make sure the circuit is fully discharged before removing test leads, LCD
should read close to zero volts.
• Always adhere to local and national safety codes.
• Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are
exposed.
• Never apply voltage or current to the meter that exceeds the specified maximum.
• Use extreme CAUTION when working with high voltages.
• Do not measure voltage if the voltage on the “COM” input jack exceeds 1000V above earth ground.
• Never connect the meter leads across a voltage source while the function switch is in the current, resistance or
diode mode, doing so can damage the meter.
• Always discharge filter capacitors in power supplies and disconnect the power when making resistance or diode
tests.
• Always turn off the power and disconnect the test leads before opening the covers to replace the fuse or batteries.
• Never operate the meter unless the back cover and the battery and fuse covers are in place and fastened securely.
• If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment
may be impaired.

4-3.Low Z AC/DC Voltage Measurement
CAUTION: Observe all safety precautions when working on live voltage. Do not connect to circuits that exceed
1000V when the meter is set to Low z. Do not use Low Z when testing circuits that could be harmed by this function’s
low input impedance. Let the meter stabilize 15 minutes after using Lo Z.
• Low Z is used to check for “ghost” voltage.
• Ghost voltages are present when non-powered wires are in close proximity to wires powered wires.
• Capacitive coupling between wires make it appear that non-powered wires are connected to a real source of
voltage.
• The Low Z setting places a load on the circuit, which greatly reduces the voltage reading when connected to
ghost voltage.
1.Set the function switch to the Low Z Position.
2.Insert the black test lead into the Input Terminal COM and the red test lead into the Input Terminal V/Hz/3000A
