DANGER
Probe Connection, Measurement Voltage input
Maximum input voltage ratings for the CH1, CH2 and the external control
terminals are shown below. To avoid the risk of electric shock and
damage to the unit, take care not to exceed these ratings.
The maximum rated voltage to earth of the CH1, CH2 and external
control terminals (voltage between each channel and the 8730-10,
8731-10, between channels, and between an external control terminal
and the 8730-10, 8731-10) is shown below. To avoid the risk of electric
shock and damage to the unit, take care that voltage between
channels and between a channel and ground does not exceed these
ratings.
The maximum rated voltage to earth rating applies also if an input
attenuator or similar is used. Ensure that voltage does not exceed
these ratings.
Power cord Connection
Before using the product, make sure that the insulation on the power
cord is undamaged and that no bare conductors are improperly
exposed. Using the product under such conditions could result in
electrocution. Replace the power cord specified by Hioki .

WARNING
Power Supply Connections
Before turning the product on, make sure the source voltage
matches that indicated on the product's power connector.
Connection to an improper supply voltage may damage the product
and present an electrical hazard.
NOTE
Be sure to select a suitable input voltage axis range to avoid range-over. (See
4.3.1 and 4.3.5)
If a range-over occurs, a warning message appears and the ERROR terminal of
the external control terminals is activated. You can enable or disable this
function. (See 7.5.3)
The measurable range of each range is -10 times to +11 times the voltage axis
range. If input exceeds the measurable range, a range-over occurs, and the
waveform is shown in black.
