10. OPERATIONS
10.2 Operations at Abnormal Inputs
1 Over-range input
The following table shows displays and printings for input exceeding a printing range or a measuring range.
•Measuring range:
Determined by the range No. programmed in “Range/Printing range”. See Section 8.2.
•Printing range:
Trace printing range programmed in “Range/Printing range”.

*For the digital display and printing, the measured values can be displayed and printed up to about ±10% of the span even when the values are outside the measuring range.

Input Disconnection
The display and printing, when the input is disconnected, differ depending on the “Burnout enable/disable” programming. However, for channels of a voltage (mV or V) range, the burnout function is “disable (non)” even when “Burnout Enable/Disable” is programmed. Program “Burnout enable/disable” to each channel. See Section 11.11.
