Current Range (Current, CURRENT RANGE)
The current range can be fixed (when auto range is set to off) or determined automatically (when auto range is
set to on).
Fixed Ranges
When the current range is fixed, you can select a range from the available options. The selected current range
does not change even if the amplitude of the input signal changes. Set the range in reference to the rms value of
the input signal.
760901(30A High Accuracy Element)
• When the Crest Factor Is Set to CF3
Select from 500mA, 1A, 2A, 5A, 10A, 20A, and 30A.
• When the Crest Factor Is Set to CF6 or CF6A
Select from 250mA, 500mA, 1A, 2.5A, 5A, 10A, and 15A.
760902 (5A High Accuracy Element)
• When the
Select from 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A, 2A, and 5A.
• When the Crest Factor Is Set to CF6 or CF6A
Select from 2.5mA, 5mA, 10mA, 25mA, 50mA, 100mA, 250mA, 500mA, 1A, and 2.5A.
Auto range
This is the same as the auto range feature for voltage.
• When the secondary output of a CT (current transformer) or a clamp-type current sensor that outputs
current is being applied to the current input terminal, set the current range according to the maximum value
of the CT or current sensor output. Then, use the scaling feature to set the CT ratio or the conversion ratio
of the clamp-type current sensor that outputs current.
Auto Current Range (Auto (Current), AUTO (CURRENT RANGE))
This is the same as the auto range feature for voltage.
