4. SCPI error information
4.1. Introduction
Any errors that occur during the work process are recorded in the error queue until the error
queue is full. The error information can be read through the panel menu or programming
commands.
Errors are retrieved in the order of first-in, first-out, and the first error returned is the earliest
error. Each time it is read, one error item is deleted from the error queue. If there is no error
currently, i.e. the error queue is empty, the power supply will return the message "+0 No
error" when sending the query command.
4.2. Check error information
In remote control mode, execute the following command to read and clear an error message
in the error queue:
SYSTem:ERRor?
The information returned by this command is a string, such as:
“+101 Invalid character”
This error message indicates that there are invalid characters in the command string received
by the power supply. If all error information is read or no error occurs when query the error
queue, executing the "SYSTem:ERRor?" command will return information:
“+0 No error”
This message means that there is no error or that the error message has all been cleared.
The following subsections will describe in detail the meanings of error codes which is
returned by the power supply.
