(Basic)
Insulation
resistance
measurement To test the insulation resistance of
an electrical facility.

3.2 (P.62)
Voltage
measurement To measure the voltage of an exter-
nal circuit, e.g., commercial power
supply.

3.3 (P.79)
Temperature
measurement To measure a temperature

3.4 (P.82)
(Applied)
Timer To automatically end measurement
after a predetermined time.

4.1 (P.85)
Display
PI and DAR
values To check whether the insulation re-
sistance increases with time after a
voltage is applied.
[When the PI (polarization index)
value or the DAR (dielectric absorp-
tion ratio) value is close to 1, the in-
strument determines that the
insulation of the object to be mea-
sured has deteriorated.]

4.2 (P.89)
Temperature
compensa-
tion (TC) To obtain the insulation resistance
at various temperatures varied from
the actual environmental tempera-
ture at which measurement is per-
formed.

4.3 (P.93)
