1) 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 a 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/IE /EN61010-1 Ed. 2 & 3, IE /EN61010-2-030 Ed. 1, AN/ SA 22.2 No. 61010-

Measurement ategory IV 1000V A & D .

Per IEC61010-1 (2010) OVERVOLTAGE CATEGORY

OVERVOLTAGE CATEGORY ll (CAT II) is for equipment intended to be supplied

from the building wiring. It applies both to plug-connected equipment and to

PERMANENTLY ONNE TED EQUIPMENT.

OVERVOLTAGE CATEGORY lll (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 lV (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

overcurrent 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.

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 VD or 30 VA 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 hand-held 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 AT

IV 1000V or better.

This lamp-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.

AutoCheckTM mode

This innovative AutoCheckTM feature automatically selects measurement function of

ACV Hz, CV, or Resistance (Ω

ΩΩ

Ω) based on the input via test leads.

●With no input, the meter displays “Auto” when it is ready.

●With no voltage signal but a resistance below 10MΩ (nominal) is present, the meter

displays the resistance value. When the resistance is below the “Audible Threshold”,

the meter further gives a continuity beep tone.

●When a signal above the voltage threshold of 1.5V D or A up to the rated 1000V is

present, the meter displays the voltage value in appropriate D V or A V, whichever

larger in peak magnitude.

Note:

*Range-Lock and Function-Lock Feature: When a measurement reading is being

dis layed in AutoCheckTM mode, ress the RANGE or ELECT button momentarily 1

time can lock the range or function it was in. Press the button momentarily re eatedly

to ste through the ranges or functions.

*As Hazardous-Alert: When making resistance measurements in AutoCheckTM

mode, an unex ected dis lay of voltage readings alerts you that the object under test

is being energized.

*Ghost-voltage Buster: Ghost-voltages are unwanted stray signals cou led from

adjacent hard signals, which confuse common multimeter voltage measurements. Our

AutoCheckTM mode rovides low (ram -u ) in ut im edance (a rox. 2.5kΩ at low

voltage) to drain ghost voltages leaving mainly hard signal values on meter readings. It

is an invaluable feature for recise indication of hard signals, such as distinguishing

between hot and o en wires (to ground) in electrical installation a lications.

WARNING:

AutoCheckTM mode in ut im edance increases abru tly from initial 2.5kΩ to a few

hundred kΩ’s on high voltage hard signals. “LoZ” dis lays on the LCD to remind the

users of being in such low im edance mode. Peak initial load current, while robing

1000VAC for exam le, can be u to 566mA (1000V x 1.414 / 2.5kΩ), decreasing

abru tly to a rox. 3.37mA (1000V x 1.414 / 420kΩ) within a fraction of a second. Do

not use AutoCheckTM mode on circuits that could be damaged by such low in ut

im edance. Instead, use rotary-switch selector or high in ut im edance voltage

modes to minimize loading for such circuits.

VF -ACV

& ACV

functions

Inputs are made through the test leads terminals.

VF -ACV Hz function is to deal with VFD (Variable Frequency Device) signals. It,

however, further pre-selects the most appropriate voltage-ranges and thus the Hz

trigger levels to best cope with most VFD-Voltage and VFD-Frequency applications.

Note: The Hz trigger level is determined by the AC/ C+AC Voltage or Current

function-range being in use. Press RANGE button to select

different

function-ranges

and thus

trigger levels manually.

CV & C+ACV

(Model 197 only) functions

Inputs are made through the test leads terminals. Defaults at CV Function. Press

SELECT button momentarily and release to select C+ACV Hz.

ACA

, CA & C+ACA

(Model 197 only) functions

Input is made through the clamp jaws for non-invasive current measurements. Defaults

at ACA Hz Function. Press SELECT button momentarily and release to select the

subject functions in sequence.

CAUTION (Application and removal of the Clamp-on meter)

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. Locate the conductor(s) at the

Jaws center 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

will affect measurement accuracy. Keep the jaws away from them as much as possible

to minimize influence.

Ω

ΩΩ

Ω Resistance & Continuity functions

Inputs are made through the test leads terminals. Defaults at Ω

ΩΩ

Ω Resistance. Press

SELECT button momentarily and release to select. Continuity

Capacitance & iode functions

Inputs are made through the test lead terminals. Defaults at Capacitance. Press

SELECT button momentarily and release to select iode.

Note

When using Diode test function, normal forward voltage dro (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 o en diode (defective). Reverse the test leads connections (reverse

biased) across the diode. The digital dis lay shows OL if the diode is good. Any other

readings indicate the diode is resistive or shorted (defective).

CAUTION

1. Using Resistance, Continuity, Diode or Ca acitance function in a live circuit will

roduce false results and may damage the meter. In many cases the sus ected

com onent(s) must be disconnected from the circuit to obtain an accurate

measurement reading.

2. When using Ca acitance function, discharge ca acitor(s) before making any

measurements. Large value ca acitors should be discharged through an a ro riate

resistance load

Temperature function (Model 197 only)

Defaults at oC ( elsius) readings. Press SELECT button momentarily and release to

select oF (Fahrenheit) readings. Inputs are made through the test leads terminals. Be

sure to insert the banana plug type-K temperature bead probe Bkp60 with correct

polarities. You can also use a plug adapter Bkb32 (Optional purchase) with

banana pins to type-K socket to adapt other type-K standard mini plug temperature

probes.
