I. SAFETY :

This manual contains information and warnings that must be followed for operating the instrument safely and maintaining the instrument in a safe operating condition. If the instrument is used in manner not specified by the manufacturer, the protection provided by the instrument may be impaired.

The meter protection rating, against the users, is double insulation per UL/IEC/EN61010-1 Ed. 3, IEC/EN61010-2-033 Ed. 1, CAN/

CSA C22.2 No. 61010-1 Ed. 3, IEC/EN61010-2-032 Ed. 2 & IEC/

EN61010-031 Ed. 1.1 :

Measurement Category III 1000V & Category IV 600V AC & DC.

Per IEC610-1 (2010) OVERVOLTAGE CATEGORY

OVERVOLTAGE CATEGORY II (CAT II) is for equipment intended to be supplied from the building wiring. It applies both to plugconnected equipment and to PERMANENTLY CONNECTED

EQUIPMENT.

OVERVOLTAGE CATEGORY III (CAT III) is for equipment intended to form part of a building wiring installation. Such equipment includes socket outlets, fuse panels, and some MAINS installation control equipment.

OVERVOLTAGE CATEGORY IV (CAT IV) is for equipment installed at or near the origin of the electrical supply to a building, between the building entrance and the main distribution board. Such equipment may include electricity tariff meters and primary over current protection devices.

Terms in this manual :

WARNING Identifies conditions and actions that could result in serious injury or even death to the user.

CAUTION Identifies conditions and actions that could cause damage or malfunction in the instrument.

01

®

WARNING :

To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The meter is intended only for indoor use.

To avoid electrical shock hazard, observe the proper safety precautions when working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to the user.

Before and after hazardous voltage measurements test the voltage function on a known source such as line voltage to determine proper meter functioning.

Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads) that indicate the limits of safe access of the handheld part during measurement. Inspect test leads, connectors and probes for damaged insulation or exposed metal before using the instrument. If any defects are found, replace them immediately. Only use the test lead provided with the equipment or UL Listed Probe

Assembly rated CAT III 1000V or better.

This Clamp-on meter is designed to apply around or remove from uninsulated hazardous live conductors. But still, individual protective equipment must be used if hazardous live parts in the installation where measurement is to be carried out could be accessible.

CAUTION :

Disconnect the test leads from the test points before changing meter functions.

CAUTION & WARNING for Non-Invasive (Clamp-on) Current

Measurements :

CAUTION :

(Application and Removal of the Clamp-on Jaws) For non-invasive current measurements, press the jaw trigger and clamp the jaws around conductor(s) of only one single pole of a circuit for load current measurement. Make sure the jaws are completely closed, or else it will introduce measurement errors. Enclosing conductor(s) of more than one pole of a circuit may result in differential current (like identifying leakage current) measurement. Align the conductor(s) to

TM the Jaws center indicators (Regular or AmpTip indicators where applicable) as much as possible to get the best measuring accuracy.

For removal, press the jaw trigger and remove the jaws from the conductor(s).

Adjacent current-carrying devices such as transformers, motors and conductor wires may affect measurement accuracy. Keep the jaws away from them as much as possible to minimize influence.

WARNING :

Do not use the meter to measure currents above the rated frequency

(400Hz). Circulating currents may cause the magnetic circuits of the

Jaws reach a hazardous temperature.

15

®

ACA, DCA, DC+ACA, & Hz :

Input is made via the clamp jaws with best accuracy specified near the jaw tip area for small conductors low-current measurements.

Press SELECT button momentarily to select the subject functions in sequence. Last selection will be saved as power up default for repeat measurement convenience. Press Hz button momentarily to toggle the Hz function.

Note : When using diode test function, normal forward voltage drop

(forward biased) for a good silicon diode is between 0.400V to

0.900V. A reading higher than that indicates a leaky diode (defective).

A zero reading indicates a shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections

(reverse biased) across the diode. The digital display shows OL if the diode is good. Any other readings indicate the diode is resistive or shorted (defective).

CAUTION :

Using Resistance, Continuity or Diode function in a live circuit will produce false results and may damage the meter. In many cases the suspected component(s) must be disconnected from the circuit to obtain an accurate measurement reading.

To wake up the meter from APO, press the SELECT button momentarily and release, or turn the rotary switch OFF and then back on. Always turn the rotary switch to the OFF position when the meter is not in use.

V. MAINTENANCE :

WARNING :

To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input jacks and turn OFF the meter before opening the case. Do not operate with open case.

Trouble Shooting :

If the instrument fails to operate, check batteries and test leads etc., and replace as necessary. Double check operating procedure as described in this manual.

If the instrument voltage-resistance input terminal has subjected to high voltage transient (caused by lightning or switching surge to the system under test) by accident or abnormal conditions of operation, the protective impedance components in series might be blown off

(become high impedance) like open fuses to protect the user and the instrument. Most measuring functions through this terminal might then be open circuit. Such components should only be replaced by qualified technician. Refer to the WARRANTY section for obtaining warranty or repairing service.

22

®

Cleaning and Storage :

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 30 days, remove the batteries and store them separately.

Battery replacement :

The meter uses standard 1.5V AA Size (IEC R6) battery X 2.

Loosen the 2 captive screws from the battery cover case. Lift the battery cover case. Replace the batteries. Replace battery cover case. Re-fasten the screws.
