Specify the measurement range to switch to when a peak over-range occurs.
30 A input element 760901
(OFF, 30A, 20A, 10A, 5A, 2A, 1A, 500mA)
5 A input element 760902
(OFF, 5A, 2A, 1A, 500mA, 200mA, 100mA, 50mA, 20mA, 10mA, 5mA)
Input element 760901 or 760902 with external current sensor:
(OFF, 10V, 5V, 2V, 1V, 500mV, 200mV, 100mV, 50mV)
Current sensor input element 760903:
When Terminal (see section 2.2) is set to Sensor, the options vary depending on the CT type.
For the current range options, see
“Current Range (Current, CURRENT RANGE)” in the
features guide
.
When Terminal is set to Probe,
(OFF, 10V, 5V, 2V, 1V, 500mV, 200mV, 100mV, 50mV)
• When Range Σ Link is set to on (see section 2.1), the input elements that are assigned to the same
wiring unit are set to the same range.
• If auto range is on (you can turn it on by pressing AUTO), the instrument operates as follows:
• When a peak over-range occurs, the measurement range increases to the range specified here,
skipping the ranges in between.
• When the measurement range to switch to when a peak over-range occurs has not been selected,
the measurement range increases in the order of the specified valid measurement ranges.
