Series 3700 System Switch/Multimeter Reference Manual
The commands to control the error queue are listed in the following table. When you read a
single message in the error queue, the ―oldest‖ message is read and then removed from the
queue. On power-up, the error queue is initially empty. If there are problems detected during
power-on, entries will be placed in the queue. When empty, the error number 0 and ―No Error‖ is
placed in the queue. Messages in the error queue include a code number, message text,
severity, and TSP-Link node number.
