1. Set the function switch according to the measurement object, to
500 V or 15 V.
2. Connect the black plug of the black test lead to the E terminal on
the left and the amber plug of the red test lead to the L terminal on
the right as shown in Fig. 4.
3. Connect the black clip to a measuring point on the measurement
object and the tip of the red test rod to the other point, and press the
POWER switch. The INSUL. TEST VOLT ON switch will light up
and the resistance measurement value will be shown on the LCD.
4. When the measurement object has resistance of more than
200 MΩ at 500 V or 20 MΩ at 15 V, the LCD shows the same over-
input display as that displayed when the measuring terminals are
open, as shown in Fig. 1 under section [4]4-2, “Checking the Built-
in Batteries” on page 5.
5. After measurement, press the POWER switch again to OFF or set
the function switch to OFF.
NOTE: Distiaction Between E and L Terminals
When one of the measuring points is grounded, connect it to the E
terminal of the instrument.
This is specified in consideration of safe use, because the resistance
measurement value reading in the insulation testing can be reduced
in this way. In other measurement operations, consideration of the
polarity of measurement points is not necessary.
