Table 30. 8842A Get Commands
Command Output String Description
G0
frst f = 1 – 6 for function selection
r = 1 – 6 for selected range
s = 0 – 2 for selected measurement rate
t = 0 – 4 for selected trigger mode
G1
nn nn = 00 for SRQ disabled
01 for SRQ on overrange
16 for SRQ on data available
32 for SRQ on any error
Note: SRQ mask values may be added for
combinations. Example: 33 for SRQ on
overrange or any error.
G2 Error 51 Not supported in 8842A emulation mode.
G3

a = 0 Autorange on
1 Autorange off (manual ranging)
b = 0 Offset off
1 Offset on
G6

1 Output suffix enabled
w = 0 – 5 Selected terminator command
G7
[1]
10nn nn = Error code
G8 FLUKE,8842A, nnnnnnn,V5.0 nnnnnnn = Instrument serial number
[1] The 8845A and 8846A have an error queue of 16. For multiple errors, G7 will dequeue the errors one by one but
will not clear the ERROR indicator on the front panel when the queue is empty. X0 clears the ERROR annunciator.
The output data from some Get commands starts with a leading 1 or 10. This prevents the
controller from suppressing leading zeroes and gives a uniform four-character length
to all instrument configuration data (the data from Get commands G0, G4, G5, G6, and
G7).
The Get commands are described further in the following paragraphs. For more
information about output data, see Syntax Rules later in this section.
G0 (Get Instrument Configuration)
The G0 command copies the function, range, reading rate, and trigger mode of the Meter
into the output buffer in the format shown in Figure 7. The four digits returned represent
the arguments for the equivalent F, R, S, and T commands, as shown in Table 30. An
example output string follows:
