G3 (Get User-Defined Message); G4 (Get Calibration Status) - Fluke 8842A Instruction Manual

3-15. G3 (Get User-Defined Message)

The G3 command loads the output buffer with the user-defined message stored in
calibration memory during the calibration procedure. The message consists of 16 ASCII
characters, as shown in Figure 3-6.
The message is stored in calibration memory during calibration using the P3 command. If
fewer than 16 characters have been stored, the remaining characters returned are spaces.
If no message has ever been stored, a string of 16 null characters (hex 00) will be
returned. Some example output strings follow.
Example
FL8842A.12-17-83 CR LF
01-25-84 CR LF

3-16. G4 (Get Calibration Status)

The G4 command is used when calibrating the 8842A under remote control. The
command loads the output buffer with the instrument's calibration status in the format
shown in Figure 3-6. The status is represented by a four-digit integer which is interpreted
in Table 3-1.
The first two digits are always 1 and 0. The third digit indicates whether or not the
calibration verification mode is enabled. (This mode is enabled only when the calibration
mode is enabled.) The fourth digit indicates whether or not the calibration mode is
enabled, and if so, which part of the calibration procedure the 8842A is in. Example
output strings follow.
Example
1000 CR LF
1001 CR LF
