three-conductor type with the correct pin connected
to earth ground to prevent electric shock.
Before connecting to an AC outlet or external power source, be sure that the power switch is in
the OFF position and verify that the AC power cord, including the extension line, is compatible
with the rated voltage/current and that there is sufficient circuit capacity for the power supply.
Once verified, connect the cable firmly.
The included AC power cord is safety certified for this
instrument operating in rated range. To change a
cable or add an extension cable, be sure that it can
meet the required power ratings for this instrument.
Any misuse with wrong or unsafe cables will void the
warranty.
Fuse Requirements
An AC input fuse is necessary when powering the instrument. Refer to the table below for the
fuse requirements.
Model
Fuse Specification (110 V)
Fuse Specification (220 V)
9801
T 10 A, 250 V
T 6.3 A, 250 V
*9803
2 x T15A, 250V
*9805
2 x T30A, 250V
Table 1 – AC Input Fuse Table
* The 9803 and 9805 both have 2 fuses inside each instrument. The 9803 has two T15 A, 250V
rated fuses while the 9805 has two T30 A, 250V fuses. Both fuses must be installed for 110 V
or 220 V operation.
When 110 V line voltage is selected, both fuses are connected in parallel internally.
When 220 V line voltage is selected, both fuses are connected in series internally.
