Programmable AC/DC Electronic Load 63800 Series Operation & Programming Manual
Service Request The AC Load sets the SRQ line true if there is an enabled
service request condition.
Remote/Local
The AC Load powers up in local state. In local state, the
front panel is operative, and the AC Load responds to the
commands from GPIB. In remote state*, all front panel
keys except the "<CONF./LOCAL>" key are disabled.
Press "<CONF./LOCAL>" key to return the AC Load to
local state.

Introduction to Programming
All commands and response messages are transferred in form of ASCII codes. The response
messages must be read completely before a new command is sent, otherwise the remaining
response messages will be lost, and a query interrupt error will occur.
