At-a-glance Table of Operations When Overload or Low C is Detected
Operations when overload/Low C is detected
Operations when overload/Low C is detected
Table E-1 shows operations of the 4288A when one of the following items is detected:
❏ Overload:
• When the available measurement range is exceeded more than 18% (refer to
“Specifications and Supplemental Performance Characteristics” in Operation
Manual)
• When nothing is connected to the UNKNOWN terminal
❏ Low C:
• When measured primary parameter result is equal to or less than the boundary
value specified for the Low C reject function
❏ Out of display range:
• When measured result exceeds the allowable display range (refer to “Specifications
and Supplemental Performance Characteristics” in Operation Manual) (regardless
of fixed or floating point display)
• When measured result exceeds the allowable display range for the fixed point
display

ment (judgment result when no error occurred).
*2.When an out-of-display-range state is detected, measurement is performed normally but the measured values are
not displayed.
