!Safety Information

To ensure safe operation and service of the meter,

follow these instructions. Failure to observe warnings

can result in severe INJURY or DEATH.

WARNING identifies hazardous conditions and

actions that could cause bodily harm or death.

- If the equipment is used in a manner not specified

by the manufacturer, the protection provided by the

equipment may be impaired.

- Always use proper terminals and range for

measurements.

- Always use proper terminals, switch position, and

range for measurements.

- To reduce the risk of fire or electric shock, do not

use this product around explosive gas or in damp

locations.

- Verify the Meter operation by measuring a known

voltage. If in doubt, have the Meter serviced.

- Do not apply more than the rated voltage, as

marked on Meter, between terminals or between

any terminal and earth ground.

- To avoid false readings that can lead to electric

shock and injury, replace battery as soon as low

battery indicator appears.

- Avoid working alone so that assistance can be

rendered.

- Do not use the Meter if the Meter is not operating

properly or if it is wet.

- Individual protective device must be used if

hazardous live parts in the installation where the

measurement is to be carried out could be

accessible.

- When using test leads or probes, keep your fingers

behind the finger guards.

Warning

!

- Use caution with voltages above 30 Vac rms, 42 Vac

peak, or 60 Vdc. These voltages pose a shock hazard.

- Remove test lead from Meter before opening the

battery door or Meter case.

- DO NOT USE the test leads when the internal white

insulation layer is exposed.

- DO NOT USE the test leads above maximum ratings

of CAT. environment, voltage and current, that are

indicated on the probe and the probe tip guard cap.

- DO NOT USE the test leads without the probe tip

guard cap in CAT III and CAT IV environments.

- Probe assemblies to be used for MAINS measure

ments shall be RATED as appropriate for MEAS

UREMENT CATEGORY III or IV according to IEC

61010-031 and shall have a voltage

RATING of at least the voltage of the circuit to be

measured.

- Disconnect circuit power and discharge all high

voltage capacitors before testing resistance, continuity,

diodes, or capacitance.

- Do not use a flexible current sensor if the inner copper

wire of the insulation of the flexible cord is visible.

- De-energize the installation under test or wear suitable

protective clothing during fitting and removal of the

Flexible Current Probe.

- Do not apply around or remove from UNINSULATED

HAZARDOUS LIVE conductors, which may render

electric shock, electric burn, or arc flash.

!

Caution

CAUTION identifies conditions and actions that could

damage the Meter, the equipment under test, or cause

permanent loss of data.

- Remove the batteries if the Meter is not used for an

extended period of time, or if stored in temperatures

above 50 °C. If the batteries are not removed, battery

leakage can damage the Meter.

- Do not expose Meter to extremes in temperature of

high humidity.

CAT III equipment is designed to protect

against transients in equipment in fixed

equipment installations, such as

distribution panels, feeders and short

branch circuits, and lighting systems in

large buildings.

CAT IV equipment is designed to protect

against transients from the primary

supply level, such as an electricity Meter

or an overhead or underground utility

service.

Unlock / Lock Clamp Jaw

Turn the clamp lock counter-clockwise to release the

flexible clamp. Fully enclose only one conductor of the

device under test with the flexible clamp probe.

Re-secure the clamp lockafter clamping around a

single conductor.

Position Error

When measuring current, move a single cable in the

center of the flexible clamp jaw. It can make less the

position error.

Voltage & Resistance Measurement

• When connecting the test leads to the DUT (Device

Under Test) connect the common test leads before

connecting the live test leads; When removing the test

leads, remove the live test leads before removing the

common test leads.

• Do not use the LoZ mode to measure voltages in

circuits that could be damaged by this mode’s low

impedance (approx. 4kΩ).

Battery Replacement

Maintenance

Verify the Meter’s operation by measuring a known

voltage. If in doubt, have the Meter serviced. Do not

attempt to repair this Meter. It contains no user

serviceable parts. Repair or servicing should only be

performed by qualified personnel. To maintain the best

accuracy, calibrate Meter once per year.

Cleaning

Periodically wipe the case with a dry cloth and

detergent do not use abrasives or solvents.

Storage

Remove the batteries if the Meter is not used for an

extended period of time, or if stored in temperatures

above 50 °C. If the batteries are not removed, battery

leakage can damage the Meter.
