program. In the program it is recommended to send the command for
enabling outputs (for example, :OUTPut ON) as the last command.
With this procedure it is possible to switch off the error check system
(:SYSTem:CHECk OFF) to increase programming speed.
The error check is enabled again by sending *RST.
