Valid measurement range
• The measurement range switches (in order) between the ranges whose check boxes
are selected.
• Ranges whose check boxes are not selected are skipped.
• When Element Independent (see section 1.9) is set to OFF, the input elements that are
assigned to the same wiring unit are set to the same status.
If the measurement range to switch to when a peak over-range occurs
has been selected, the range background is displayed in yellow.
For each input element or wiring unit,
you can set all ranges as valid
measurement ranges (All ON).
Available options for the measurement

Measurement range to switch to when a peak over-range occurs
• When Element Independent is set to OFF, 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), this 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
is set to OFF, the measurement range increases in the order specified by
the measurement ranges whose check boxes have been selected.
