Code Status or error titles
-849
ILimit command is not supported for RPM in slot %d, channel %d.
-850
Sample Rate mismatch. All channels in test must have the sample rate.
-851
Invalid PxU stepper/sweeper configuration.
-900
Environment variable KI_PRB_CONFIG is not set. The prober drivers will be inaccessible.
-901
Environment variable KI_PRB_CONFIG contains an invalid path. The prober drivers will be
inaccessible.
-902
Prober configuration file not found. File was %s. The prober drivers will be inaccessible.
-903

User Module (UTM) error codes. Refer to user module description (help) for details.
Large number reported readings and explanations
Measurement Value Condition
1.0000E+22 or
10.0000E+21
SMU is in range compliance (see Compliance limits (on page 3-3)), where the
reading is at the maximum of a fixed range.
5.0000E+22
SMU measurement at the maximum SMU voltage or current.
7.0000E+22
SMU in real compliance (see Compliance limits (on page 3-3)).
1.0000E+23
Measurement aborted or not able to be performed. For example, if using LPT
command to make a measurement, but the SMU output was not enabled, then
this measurement value will be reported.
LPT library and Clarius interaction when using UTMs
ITMs and UTMs are typically independent. However, an ITM and a UTM are not independent if the
UTM occurs before an ITM in the project and the UTM configures a switch matrix. Under these
conditions, the following occur:
• Clarius assumes that the ITM depends on the UTM-created switch configuration.
• Clarius maintains the UTM-created switch configuration during execution of the ITM.
Clarius actions affected by ITM and UTM sequence
Test sequence in the project Clarius action
A UTM precedes an ITM
Before the ITM executes, the devint command initializes all devices,
except for the switch matrix (the switch configuration is preserved to run
the subsequent ITM).
A UTM precedes a UTM
No initialization operations occur.
An ITM precedes an ITM
No LPT library calls occur.
An ITM precedes a UTM
Before the UTM executes, the devint command initializes all devices,
including the switch matrix.
