 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 ing the position of the function rotary switch.
˙ 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 userservice­able parts. Repair or servicing should only be performed by

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.

4

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

5

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.

6

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

=

7

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,200MΩ and 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.

8

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.

9

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.
