3.4 Turning Power On and OFF
Turning Power On
• Before turning on the instrument, confirm that the voltage of the power
source matches the voltage specification indicated on the instrument's
power connector ([AC IN]). (The voltage specification (100, 120, 220 or
240 V) ordered by the customer is marked with a black dot in the line
voltage column on the rear panel.)
Note that using the power supply with improper voltage may damage the
instrument and result in electrical hazards.
• To avoid electrical accidents and to maintain the safety specifications of
this instrument, connect the power cord provided only to a 3-contact
(two-conductor + ground) outlet.
• Before turning on the power switch, confirm that the circuit breaker is turned
off. Even if the instrument was turned off in fault mode (i.e., disconnection of
one wire in the power line) at last use, the instrument will be initialized to nor-
mal condition when the power switch is turned on. Therefore, the terminal
block outputs voltage.
• The instrument can operate continuously for 30 minutes at maximum load.
Measurements that continue for longer than 30 minutes may raise internal
temperature and thereby trip the circuit breaker.
