UNIT

NOTE
Main power switch (POWER)
Powers the 9196 on and off.
Main power switch indication: ｜ : ON ○ : OFF
Main power monitor (POWER MONI): Clear monitor lamp
The status of the main power is shown by this monitor lamp.
If illuminated, the power is ON.
If not illuminated, the power is OFF.
Polarity toggle switch (POLARITY)
This switch is used to toggle the polarity of the voltage output from the
voltage application probe. (in respect to the voltage input from the power inlet)
NORMAL : Polarity conforms with that of the voltage input from the power
inlet.
REVERSE : Polarity does not conform with that of the voltage input from the
power inlet.
Type toggle switch (TYPE)
Changes per the type of applied part of the equipment to be measured to
which voltage is applied.
B/BF : No protective resistance connected to the output point of the voltage
application probe.
C F : Protective resistance (10 k Ω ) connected to the output point of the voltage
application probe in series.
When the type toggle switch of the 9196 APPLY UNIT is set to CF, there is a
10 k
Ω protective resistance connected to the output point of the voltage
application probe in series. If the leakage current is large, the current flowing
from the output point will be subject to a reduction in voltage due to the
protective resistance, thereby reducing the actual output voltage.
