Usage Notes
Handling the cords and leads
DANGER
To avoid electric shock, be careful to avoid shorting live lines with the
test leads.
WARNING
Before using the instrument, check that the coating of the cords are
not either ripped or torn and that no metal parts are exposed. If any
damage is found, contact your authorized Hioki distributor or reseller
to prevent electric shock.
CAUTION
•
To avoid damage to the instrument, do not short connectors or output
components or input voltage.
•
To avoid damage to the instrument, do not apply voltage or current to the
analog output terminal or EXT.SW terminal.
•
Avoid stepping on or pinching the cables, which could damage the cable
insulation.
•
To avoid breaking cables or lead wires, do not bend or pull them at the
base.
•
Bare conductors could be exposed if the insulation melts. Do not touch
the heat sources.
To avoid electric shock and damage to the instrument, observe the cautions
listed below when connecting the analog output terminal, RS-232C
connector, and EXT.I/O terminal.
•
Always turn off the power on the instrument and on any devices to be
connected before making connections.
•
Be careful to avoid exceeding the rating of the analog output terminal,
RS-232C connector, or EXT.I/O terminal signal.
•
During operation, a wire becoming dislocated and contacting another
conductive object can cause serious hazard. Use screws to secure the
external connectors.
•
Properly isolate the devices and equipment to which the analog output
terminal, RS-232C connector, and EXT.I/O terminal are connected.
•
To avoid damaging the cord, grasp the plug, not the cord, when
unplugging the output connector.
•
The cables can become hard in the environment at a temperature of 0°C
or lower. When the cables are bent or pulled, the coating of the cables
may become damaged or may break.
