Setting the Valid Measurement Range of 50 A Input Elements (50A 
Input Element)—Direct Input 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 
ranges that this instrument can switch 
to when a peak over-range occurs
For each range, you can 
set whether the range is a 
valid measurement range 
for all input elements (All 
ON) or not (All OFF).

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.
