Do not place any objects close to the ventilation port or fan of this instrument.
If any object is placed close to the ventilation port or fan of this instrument, the air ventilation
is blocked, causing the internal temperature to increase. This can cause a fire or malfunction.
Put the power switch in the OFF position, and pull the power plug from the outlet when
a thunderstorm is near.
Thunderbolts can cause electric shock, fire, or malfunction.
Do not use this instrument if it is not functioning correctly.
Using a malfunctioning instrument (due to dropping, etc.) may cause an electric shock or a
fire. If the instrument is not functioning correctly, set the power switch to the OFF position,
remove the plug from the outlet, and then contact your nearest YOKOGAWA dealer.
When voltage is being applied to the LO terminal, do not connect it to the ground
terminal of another measuring device.
The LO terminal is not grounded and is just floating. If voltage is being applied to the LO
terminal, connecting it to the ground terminal of another measuring device may result in fire or
damage.
Do not apply a voltage exceeding the specifications between the LO terminal and the
ground.
The specified voltage is ±500 Vpeak. Applying excessive voltage may cause fire or damage.
Do not apply a voltage or current exceeding the specifications to the input terminal.
Applying a voltage/current exceeding the specifications may result in fire or damage.
The maximum permissible inputs are shown in Table 2 and Table 3.

Do not apply voltage to the COMPLETE output terminal (BNC) on the rear panel.
It can cause a fire or malfunction.
Do not apply voltage or current exceeding the specifications to the contact output of
the DIO option/CMP on the rear panel.
It can cause a fire or malfunction. The specifications of HI, GO, LO, and COMPLETE are as
follows:
- Withstand voltage between terminals: 42 Vpeak
- Withstand voltage to ground: ±42 Vpeak
- Maximum allowed current: 100 mA
