The format of the returned data can be changed using the Position Format (PF), and Leading Zeros (LZ) command. For a complete description of interrogation commands, see Ch 5.

Using the PF Command to Format Response from Interrogation Commands

The command, PF, can change format of the values returned by these interrogation commands:
