The Model 460 Gaussmeter has two IEEE-488 commands for querying the magnetic field: "FIELD?" and "ALLF?". The "ALLF?" command returns all components (X, Y, Z, etc.) of the magnetic field as a comma-separated list. The "FIELD?" command only returns one number. What is the field or component returned by "FIELD?"?
Also, is the response from "FIELDM?" appropriate to use with "ALLF?"?

The FIELD? command returns the value of the channel that was last specified by the CHNL command. There are a few commands that report the results of the channel that is specified using the CHNL command. The FIELDM? command is one of those. When you send the ALLF? command, you would need to send CHNL X; FIELDM? to see what multiplier is used with channel X. Repeat the CHNL & FIELDM? command with Y, Z & V to get the Y, Z and Vector channel. Other commands that are channel specific are the RANGE and UNIT commands.
