• The decimal point positioning
When the ENT key is pressed following setting of the upper limit value, the lower limit value and the
upper limit value both flash. The positions of the decimal points can now be changed by pressing the
and
keys.
Example: 0.00 to 10.00
Referring to the 'Units code table' on page 7 to 22, press the
,
keys specify the units.
Example: Code A = 3, B = 2

Square root extraction
• This sets a rooter (square root extraction) function for each channel.
ON:
operative
OFF: Inoperative
• This calculates square root of input values converted to % taking the specified measurement range to
be 0 to 100%.
Negative input is regarded as 0%. Data (0 to 100%) after square root extraction are converted to
scaling ranges.
Example:
With Input range 5V
Measurement range: 1 to 5V
Working value:
0 to 1000 (t/h)
