【 】2 Applications and Features
2.1 Applications
・DC insulation resistance tester to measure the insulation resistance
of electric lines and electric equipment.
2.2 Features
CAUTION
Remove components such as semi-conductors and apparatuses from the circuit of
measuring object to avoid damages when withstand of the object is unknown or
lower than rated measuring voltage of a resistance insulation tester, especially in
case of the objects you me re neasu con ct h P r c ut s.ed wit Cs o omp er
・
The measured voltage is maintained until the low insulation resistance
value at the rated current specied in IEC61557-2.
18.
Do not use the instrument in a place where corrosive or explosive
gas is produced.
19.
To prevent the protection function of the tester from being spoiled,
do not use it in a method other than specied.
・It is equipped with the discharge function.
・It is equipped with the (insulation resis ance) M Ω t measuring swit ch
that enables both one-shot and continuous measurement.
− 2 −
When handling equipment containing a hazardous live part, be
sure to wear insulative protection gear to prevent accidents. Also
be sure to observe your local and national safety regulations.
Use test leads matching the measurement category of the object
measured. If the measurement categories of the instrument and test leads
were different, the lowest measurement category would be applied.

5.2 How to Check Battery (BATTERY CHECK)
Prior to MΩ (insulation resis ance) measurement, t be sure to check eth
battery. A consumed battery will cause not only measurement errors
but danger due to erroneous measurement.
For checking methods, refer to 5.1 Start-up Check.
Do not check the battery for more than 5 seconds.

Short alligator clip (or test pin) on black
test lead with test pin on red test lead.
1. Never apply a voltage to the measuring terminal when the tester
is in the MΩ measuring range.
2. P rior to measurement, disconnect the measuring object (circuit )
from the p er supply.ow
3. Prior to measurement, ma sure no ol age is applied to th ke v t e
circuit to measure by the AC 600 V range.
4. During measurement, a high voltage is generated. Do not touch
the test pin, clip and measuring object.
5.
The tester and measured circuit have been charged by high voltage
immediately after the measurement. Be careful not to get electric
shock.
6. T a ty c Afhere is possibili of an accident of electric sho k. ter th e
mea rem di ge highsu en be e to t, sur schar the voltage charged in
the measuring object. (See 5.4 Discharge Function)
5.3 Measurement of M (Insulation Resistance) Ω
WARNING
CAUTION
1.
When the object measured is grounded, usually connect the black
EARTH (ground) test lead to the grounded side and the red LINE
test lead to the circuit. (When this connection is used, a measurement
v a v e obtained by the reverse alue becomes smaller than alu
connection.)
2. To ev a er r, k topr ent measuring ro eep the test lead connected
the LINE side out of con actt with the measuring object and ground
(earth).
3. T
he insulation resistance varies largely depending on temperature
a h ty. nd umidi It is also inue ednc by a volt to ap age ply (measuring
voltage).
Normally as tempera ure, humidi and ol age increase, th t ty v t e
insulation resistance decreases.
− 7 −
1.
The M measurement should be performed as quickly as possibleΩ
to prevent the internal parts from heating. Particularly, when measuring
resistance between 0 M to the center of scale, perform each Ω
measurement within 20 seconds and leave an equivalent interval to
the measuring time before proceeding to the subsequent measurement.
2. The no-load voltage is within 1.25 times the rated measuring
voltage.

CAUTION
1. Rated measuring voltage should be selected by a measuring
object. For example, 125 V rated measuring voltage should be
used for the object, AC input voltage of which is 100 V.
2.Remove components such as semi-conductors and apparatuses
from the circuit of measuring object to oid damages whe av n
withstand of the object is unknown or lower than rated measuring
voltage of a resistance insulation tester, especially in case of the
objects you measure connected with PCs or computers.

First remove the red test pin from the object measured, and
then disconnect the black alligator clip.
5.4 Discharge Function
1) Reason of a need to discharge
For safety, high voltage remaining in capacitive measuring objects
such as capacitors and electric wire must be discharged to prevent
accidents.
2) Discharging method (This procedure follows the step ⑧ of 5.3-4)
① ΩWhen Mthe measurement has been completed, turn off only
the MΩmeasuring switch with the test pin and the alligator clip
connected to the measuring object.
②T hen the pointer deects to the right and its deection become s
smaller as time passes (indicating the charged charge is being
discharged).
③
When the pointer stops at zero (
∞ of the M scale) and dischargeΩ
has been completed, conduct the steps ⑩ and ⑪ of 5.3-4)
