1) SAFETY

This manual contains information and warnings that must be followed for operating the

meter safely and maintaining the meter in a safe operating condition. If the meter is

used in a manner not specified by the manufacturer, the protection provided by the

meter may be impaired.

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.

Observe proper safety precautions when working with voltages above 33 Vrms, 46.7

Vpeak or 70 VDC. These voltage levels pose a potential shock hazard to the user.

Before and after hazardous voltage measurements, check the voltage function on a

known source such as line voltage to determine proper meter functioning.

The meter meets UL/IEC/EN61010-1 Ed. 3.0, CAN/CSA C22.2 No. 61010-1 Ed. 3.0,

UL/IEC/EN61010-2-033 Ed. 1.0 to Measurement CAT-III 1kV and CAT-IV 600V, AC &

DC. The meter also meets the relevant Parts of EN61557. In particular, Part 1 Ed. 2.0,

Part 2 Ed. 2.0 and Part 10 Ed. 2.0. These relevant parts of EN61557 are not covered

by the ETL certification.

The accompanied test probe assembly meets UL/IEC/EN61010-031 Ed. 1.1 to the

same meter ratings or better. IEC 61010-031 requires exposed conductive test probe

tips to be ≤ 4mm for CAT III & CAT IV ratings. Refer to the category markings on your

probe assemblies as well as on the add-on accessories (like detachable Caps or

Alligator Clips), if any, for applicable rating changes.

Keep your hands/fingers behind the hand/finger barriers (of the meter and the test

probe assembly, where applicable) that indicate the limits of safe access of the hand-

held parts during measurements. Inspect lead wires, connectors, and probes for

damaged insulation or exposed metal before using the meter. If any defects are found,

replace them immediately. Only use the probe assembly provided with the meter or a

UL Listed Probe Assembly to the same meter ratings or better.

CAUTION

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

Brief Information about Measurement Categories

Measurement Category IV is applicable to test and measuring circuits connected at

the source of the building’s low-voltage MAINS installation. Examples are

measurements on devices installed before the main fuse or circuit breaker in the

building installation.

Measurement Category III is applicable to test and measuring circuits connected to

the distribution part of the building’s low-voltage MAINS installation. Examples are

measurements on distribution boards (including secondary meters), circuit-breakers,

wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed

installation, and equipment for industrial use and some other equipment such as

stationary motors with permanent connection to the fixed installation.

Measurement Category II is applicable to test and measuring circuits connected

directly to utilization points (socket outlets and similar points) of the low-voltage MAINS

installation. Examples are measurements on MAINS CIRCUITS of household

appliances, portable tools and similar equipment.

2) CENELEC DIRECTIVES

The instruments conform to CENELEC Low-voltage directive 2014/35/EC,

Electromagnetic compatibility directive 2014/30/EU and RoHS directive 2011/65/EU.

3) PRODUCT DESCRIPTION

Note: Top of the line model is used as representative for illustration purposes. Please

refer to your particular model for function availability.

Analog bar-graph

The analog bar graph provides a visual indication of measurement like a traditional

analog meter needle. It is excellent in detecting faulty contacts, identifying

potentiometer clicks, and indicating signal spikes during adjustments.

4) OPERATION

CAUTION

Before and after hazardous voltage measurements, test the voltage function on a

known source such as line voltage to determine proper meter functioning.

ACV +Hz & VFD ACV +Hz functions

Press the SELECT button momentarily to toggle the subject functions. Last selection

will be saved as power up default for repeat measurement convenience. For ACV +Hz

function, press the RANGE button momentarily to select other ranges manually when

needed. For VFD ACV +Hz function, only 600V range is provided to best cope with the

measurements of most Variable Frequency Drives (VFD).

To select DCV function, turn the Rotary Knob to DCV position for measurements.

 Resistance, Continuity functions

Press the SELECT button momentarily to toggle the functions. Last selection will be

saved as power up default for repeat measurement convenience. Continuity function

is convenient for checking wiring connections and operation of switches. A continuous

beep tone indicates a complete wire.

CAUTION

Using resistance or continuity function in a live circuit will produce false results and

may damage the instrument. In many cases the suspected component must be

disconnected from the circuit to obtain an accurate reading

Auto leads resistance calibration

When entering the 60 range manually by RANGE button for high precision low

resistance measurement, this feature will prompt you to short the inputs for temporary

test lead resistance calibration on this range.

The fastest way is to short the leads to auto-range to the 60 range, then press the

RANGE button momentarily. The display shows ”Shrt”. Keep shorting the leads for

further 3 seconds until the display shows zero. The lead resistance is then temporarily

compensated.

The compensation value stays until the next meter power reset, and can be as high

as 5. If you need a compensation value that is higher than that, Relative Zero mode

is recommended.

Diode Test, Capacitance (Model 887 only) functions

Press the SELECT button momentarily to toggle the functions. Last selection will be

saved as power up default for repeat measurement convenience.

CAUTION

Discharge capacitors before making any measurement. Large value capacitors should

be discharged through an appropriate resistance load.

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).

DCmV, ACmV +Hz functions

Press the SELECT button momentarily to toggle the subject functions. Last selection

will be saved as power up default for repeat measurement convenience.

Temperature functions (Model 887 only)

Press SELECT button momentarily to toggle C and F readings. Last selection will be

saved as power up default for repeat measurement convenience.

Note: 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 standard type-K mini plug

temperature probes.

A, mA, µA Current functions

Press the SELECT button momentarily to toggle the DC or AC+Hz of the subject

functions. Last selection will be saved as power up default for repeat measurement

convenience.

For Model 885, A and mA functions are at different Rotary Switch positions.

Insulation Resistance function

WARNING

The two LCD icons & used together, throughout in this manual, is referred as

active measurements of Insulation Resistance function through the activation of the

TEST button on the meter or on the Remote Probe. The sources a user

value plus warning against an energized circuit of more than 30V is being

connected, before the is active. Measurements shall only be carried out on

parts of an installation or equipment that are de-energized.

Connecting to energized circuits when the is active will produce false results

and may damage the instrument. Always check with voltage functions and remove
