Numerical Display
The range of displayed values of report data is from –9999999 to 99999999 excluding
the decimal point. The decimal point position corresponds to the position of the decimal
point of the upper and lower limit span or upper and lower limit scale (for scaling).
However, special displays are used for cases given in the table below.
• Measurement channel
Item Data Condition of Measurement Channels Displayed Output
Average value When all of the data are measurement errors or over range (Blank)
Maximum and • When all of the data are measurement errors (Blank)
minimum values • Positive (+) over range 99999
• Negative (–) over range –99999
Sum value • When all of the data are measurement errors or over range (Blank)
• When the sum value exceeds approx. 3.4E + 38
9.999999E+99
• When the sum value is below approx. –3.4E + 38 –9.999999E+99
• Computation channel
Item Data Condition of Computation Channels Displayed Output
Average value When all of the data are computation errors or computation (Blank)
overflow
Maximum and • When all of the data are computation errors (Blank)
minimum values • When the maximum value exceeds 99999999 999999999
• When the minimum value is –9999999 –99999999
The decimal position that was specified when the span for the channel was
specified applies to the maximum and minimum values. For example, if the span
setting of the channel is “200.0,” then “99999999” is output when the value exceeds
“99999999.9” and “–99999999” is output when the value is below “–999999.9.”
Sum value • When all of the data are computation errors or computation (Blank)
overflow
• When the sum value exceeds approx. 3.4E + 38 9.999999E+99
• When the sum value is below approx. –3.4E + 38 –9.999999E+99
Acquiring Report Data to the Internal Memory and Saving Data to the External Storage Medium
Report data is stored to the internal memory at the time reports are created. Up to 40
report data files can be acquired in the internal memory. For the data storage function,
see section 1.17, “Data Storage Function”.
