Result values indicating an error
The following table contains errors that are returned as measured results (not as Linear Parametric
Test Library (LPTLib) return status codes). Each value has a specific meaning. If one of these values
is returned from any measurement subroutine, the test was not performed and action is required by
the Keithley programmer or manager.
Table: Errors
Value Description
1.0E22 Instrument Overrange.
Measurement instrument performed the measurement, but the resulting value was inappropriate for
the range specified. This is either from selecting the wrong range for manual ranging or from
autoranged measurement on a dynamically changing signal (slowly charging device).
2.0E22
Current Overload.
Measurement was not performed due to a shutdown condition. The source went into a current
overload condition and shutdown.
3.0E22
Oscillation Detection.
Instrument was forced into a shutdown state because oscillations were detected at the instrument.
4.0E22 Thermal Shutdown.
Instrument is dissipating too much heat. The instrument is shutdown to keep from self-destructing.
5.0E22 SOA Exceeded.
The instrument is designed to operate within the Safe Operating Area. If the programming
conditions exceed this area, this error value is returned.
6.0E22
Pulse Width Too Short.
The specified pulse width is less than the minimum specified for the instrument.
7.0E22
Source Limit.
Measurement was not performed because source was in limit.
1.0E23
Measurement Not Performed.
If an error causes a measurement not to be performed, this result is returned. Previously, if a
measurement was not taken, nothing was returned, so the result available to the user (from the
execution of the test sequence) was the previous reading. This could be confusing. Now, whenever
possible, it will return this error value as a default value.
