Operating Precautions
Before connecting a measurement cable
DANGER
Measurement cables should only be connected to the secondary side of a
breaker. Any short-circuit current at the secondary side will be cut-off by the
breaker. Connections should never be made to the primary side of a breaker,
because unrestricted current flow could damage the instrument and facilities if a
short circuit occurs.
WARNING
To avoid electric shock and short-circuit accidents, use only the specified measurement
cables to connect the instrument input terminals (HIGH and LOW terminals) to the
circuit over 70 V DC to be tested.
Before connecting a temperature sensor
IMPORTANT
Connect the temperature sensor by inserting the plug all the way in the TEMP.SENSOR
connector. Insufficient connection may cause larger errors in measured values.
Before turning the power ON
WARNING
Before turning the instrument on, make sure the supply voltage matches that
indicated on its power connector. Connection to an improper supply voltage may
damage the instrument and present an electrical hazard.
CAUTION
Avoid using an uninterruptible power supply (UPS) or DC/AC inverter with rectangular
wave or pseudo-sine-wave output to power the instrument. Doing so may damage the
instrument.
