Safety Information

Understand and follow operating instructions carefully.

Use the meter only as specified in this manual; otherwise,

the protection provided by the meter may be impaired.



WARNING

Identifies hazardous conditions and actions that could cause

BODILY HARM or DEATH

CAUTION

Identifies conditions and actions that could DAMAGE the meter

or equipment under test

WARNING

˙When using test leads or probes, keep your fingers behind

the finger guards.

˙Remove test lead from Meter before opening the battery

door or Meter case.

˙Use the Meter only as specified in this manual or the protec-

tion by the Meter might be impaired.

˙Always use proper terminals, switch position, and range for

measurements.

˙Verify the Meter’s 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.

˙Only replace the blown fuse with the proper rating as speci-

fied in this manual.

˙Use caution with voltages above 30 Vac rms, 42 Vac peak ,

or 60 Vdc. These voltages pose a shock hazard.

˙To avoid false readings that can lead to electric shock and

injury, replace battery as soon as low battery indicator =

appears.

˙Disconnect circuit power and discharge all high-voltage

capacitors before testing resistance, continuity, diodes, or

capacitance.

˙Do not use Meter around explosive gas or vapor.

˙To reduce the risk of fire or electric shock do not expose this

product to rain or moisture.

CAUTION

˙Disconnect the test leads from the test points before chang-

˙Never connect a source of voltage with the function rotary

switch in Ω,50V,100V,250V,500V,1000V position.

˙Do not expose Meter to extremes in temperature or high

humidity.

˙ Never set the meter in Ω,50V,100V,250V,500V,1000V

function to measure the voltage of a power supply circuit

in equipment that could result in damage the meter and

the equipment under test.

manual

Unsafe Voltage

To alert you to the presence of a potentially hazardous voltage,

when the Tester detects a voltage ≧2 V in resistance, ≧30 V

in insulation test, or a voltage overload (OL), the ”“ symbol is

displayed and High voltage indicator is turned on.

Maintenance

Do not attempt to repair this Meter. It contains no userservice-

able parts. Repair or servicing should only be performed by

qualified personnel.

Cleaning

Periodically wipe the case with a dry cloth and detergent.

Do not use abrasives or solvents.

Making Basic Measurements

Preparation and Caution Before Measurement

: Observe the rules of Warnings and Cautions

When connecting the test leads to the DUT (Device Under

Test) connect the common (COM) test lead before

connecting the live lead ; when removing the test leads

removing the test live lead before removing the common

test lead.

The figures on the following pages show how to make basic

measurements.

Measuring ACV/DCV：Auto sense function

Auto sense mode: The meter displays ACV or DCV whichever

is higher (>0.3V).

If the measured voltage is above 660Vac/dc, "> 660Vac/dc" will

appear on the display.

Measuring ACV/DCV

Auto sense +LPF function

Measuring Earth-Bond Resistance

1. Before starting the test :

(a) The circuit under test must be completely de-energized.

Check the fuse before testing.

Connecting to an energized circuit while the test is active

will blow the fuse.

See Testing the fuse later in this manual.

If the detected voltage is above 2V, ">2V" will appear on

the display.

In this condition, the test is inhibited.

(b) Short the test leads before measurement, and press the

blue button to compensate the probe resistance for <2Ω.

If the probe resistance is stored, “->0<-” symbol will be

displayed.

2. Lock mode :Press the Lock button to enter the Lock Mode.

Then press the TEST button to start the test. The test volt -

age will continue to be applied until the TEST/LOCK button

is pressed again.

3. The meter displays the "＞" symbol and the maximum resis-

tance for the range when measured resistance is higher than

the maximum display range.

Measuring Insulation Resistance

1. Before starting the test :

The circuit under test must be completely de-energized.

If the voltage detected is above 30V, ">30V" will appear on

the display. In this condition, the test is inhibited.

2. Press the blue button to display insulation resistance or

Leakage current during the test or when the test stops.

3. Lock mode:Press the Lock button to enter the Lock Mode.

Then press TEST button to start the test. The test voltage

will continue to be applied until the TEST/LOCK button is

pressed again.

4. Release the TEST button before removing the test leads

(to enable the tester to discharge capacitive circuits).

If the screen displays volts, wait until it reaches zero.

5. The meter displays the "＞" symbol and the maximum

resistance for the range when measured resistance is

Using the Compare function

1. Before starting the insulation test :

Press the COMP button to select the compare value among

100kΩ,200kΩ,500kΩ,1MΩ,2MΩ,5MΩ,10MΩ,20MΩ,

50MΩ,100MΩ,200MΩand 500MΩ.

2. If the measured value is greater than the selected compare

value, the green Pass indicator will be turned on.

Measuring PI/DAR

PI(Polarization Index)=R10-min/R1-min

DAR(Dielectric Absorption Rations)=R1-min/R30-sec

where

R10-min : the insulation resistance measured at the 10 minute

after pressing the TEST button.

R1-min : the insulation resistance measured at the 1 minute

after pressing the TEST button.

R30-sec : the insulation resistance measured at the 30 second

after pressing the TEST button.

The measured values after the PI test

PI=R10-min/R1-min

The measured values after the DAR test

DAR=R1-min/R30-sec

If the reading for DAR is bigger than 1.3 or PI is bigger than 2,

it indicate a good insulation quality.

When the measured resistance is higher than the maximum

range, the screen will display "Err" symbol for PI/DAR value.

TEST button : Press once to start/interrupt the PI /DAR test.

Blue button : Press once during the PI/DAR test to display the

time left of the test.

Using the Store function

Store/Recall button :

The screen will be flashing MEM symbol and the number of

stored data twice when the Store/Recall button is pressed.

1. Press once to store the voltage value during voltage test

2. Press once to store the PI/ DAR, insulation or Earth-bond

resistance value when the individual test is completed.

3. The memory is divided into five segments，each segments

has 100 maximum data. The method to store the data is first

in /first out when the memory is full.

The screen will be flashing MEM symbol and “ cLr ” on

reading twice.

Using the Recall function

Press the Store/Recall button ≧2 sec to enter/exit the RECALL

mode.

If the memory is empty, the meter will display the “nOnE ”

symbol.
