IMPORTANT SAFETY WARNINGS
WARNING
Read entire Safety Notes section regarding potential hazard and proper instructions before using this meter. In this manual
the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word
“CAUTION” is used to indicate conditions or actions that may damage this instrument.
WARNING
To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in
severe injury or death.
WARNING
• Before each use, verify meter operation by measuring a known voltage.
• Never use the meter on a circuit with voltages that exceed the category based rating of this meter.
• Do not use this meter during electrical storms or in wet weather.
• Do not use the meter or test leads if they appear damaged.
• Ensure meter leads are fully seated and keep fingers away from the metal probe contact when making measurements.
Always grip the leads behind the finger guards molded into the probe.
• Do not open the meter to replace batteries while the probes are connected.
• To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears.
• Unless measuring voltage, shut off and lockout power before measuring resistance.
• Always adhere to national and local safety codes. Use proper personal protective equipment (PPE) to prevent shock and
arc blast injury where hazardous live conductors are exposed.
• Always turn off power to a circuit or assembly under test before cutting, unsoldering or breaking the current path. Even
small amounts of current can be dangerous.
• Always disconnect the live test lead before disconnecting the common test lead from the circuit.
• In the event of electrical shock, ALWAYS bring the victim to the emergency room for evaluation, regardless of victim’s
apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.
• If any of the following occur during testing, turn off the power source to the circuit being tested: arching, flame, smoke,
extreme heat, smell of burning materials or discoloration or melting of components.
WARNING
Higher voltages require greater awareness of physical safety hazards. Before connecting the test leads; turn off power to
the circuit under test, set meter to the desired function and range; connect the test leads to the meter first, then connect to
the circuit under test. Reapply power. If an erroneous reading is observed, disconnect power immediately and recheck all
settings and connections.
WARNING
This meter is designed for trade professionals who are familiar with the hazards of their trade. Observe all recommended
safety procedures that include proper lockout utilization and use of personal protective equipment that includes safety
glasses, gloves and flame resistant clothing.

• Press x1 =
• Short the ends of the test leads together, press the SELECT button and wait until ZERO appears. The meter measures the
test leads resistance, stores the data/results in memory and subtracts it from the reading. The test lead resistance is saved
even after the meter is powered off. If the Probe resistance is >2Ω, the resistance will not be saved.
• Connect the test leads to the circuit to be tested. The tester will automatically detect if the circuit is energized.
• The display will show “----” until a valid resistance reading is detected.
• The High Voltage symbol will display if greater than 2V AC or DC is present. If the meter “chirps”when you press the
TEST button, test is corrupted due to voltage being present.
• Press and hold the TEST button on the Meter or Remote Probe to start test. Test stops when the button is released.

Test Lead Notes
CATIV 600V Measurement Locations
4mm
• Ensure the test lead shield is pressed firmly in place. Failure to use the CAT IV shield increases arc-flash risk.
CAT II Measurement Locations
18mm
• CAT IV shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard
wall outlets. Take care not to lose the shields.
WARNING: Test Lead category protections apply only to test leads and should not be confused with the meter’s specific
CAT rating. Observe the maximum category protection indicated on the meter the test leads are plugged into.

and the other end is 4mm (with cap)or 18mm (without cap) probe tip.
B) Probe length : 1618 mm ± 5.0 mm
C) Wire Color : Black / dimensions : ¢ 6mm
D) Weight : 126g
3. Specification (Dual rating)
Voltage (a.c/d.c) : 1000 V Current : Max. 10 A
Measurement Category : CAT II (without Caps) / CAT III, CAT IV (with Caps)
4. Identification of operation control
The test probe is generally attached with Digital Multi-meter. It must be in accordance with the relating meter.
(UL 61010-031, CAT II 1000V, CAT III 1000V, CAT IV 600V, 10A)
5. WARNING
• Before testing, make sure the test probe is connected to the meter. Make sure that the test probe is disconnected from
the test point before the test probe is without connection to the meter.
• If this product is used in manner not specified by the instructions, the protection may be impaired. Replace leads that
have the inner contrasting color of the wire exposed.
• Do NOT use test probe in CAT III or CAT IV environments without the cap is assembled with test probe and correct category
rating visible on the cap. When the cap is not assembled with test probe, the probe tip is 18mm and rated to CAT II 1000V.
• When used with meter or other accessories, the lowest category rating of the combination applies.
