Keysight E4981A 120 Hz/1 kHz/1 MHz Capacitance Meter
Programming Manual
D Operations when Overload, No Contact, or Low C
is Detected
This appendix describes display output, GPIB/LAN/USB output, and handler
interface output when an Overload, No contact, or Low C is detected.
Operations when Overload/No Contact/Low C is Detected
Table D-5 shows operations of the E4981A when one of the following items is
detected:
•Overload
• When the available measurement range is exceeded more than about
10% (refer to “Specifications and Supplemental Performance
Characteristics” in Operation Manual)
• When connection between the UNKNOWN terminals to DUT is not
correct
• When SLC is ON, if the applied signal level for DUT is dropped more than
10% from the setting level
•No contact:
• When the contact check parameter is over the specified threshold
•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
