command, LZ. The LZ

Local Formatting of Response of Interrogation Commands
The response of interrogation commands may be formatted locally. To format locally, use the command, {Fm.n} or
{$m.n} on the same line as the interrogation command. The symbol F specifies that the response should be
returned in decimal format and $ specifies hexadecimal. m is the number of digits to the left of the decimal, and n
is the number of digits to the right of the decimal.
