Example Explanation
FLUKE,8842A,1234567,V5.0 CR LF This Meter is a Fluke 8842A with IEEE-488 interface
software version 5.0.
N (Numeric Entry Command)
Format Explanation
N<numberic entry> Where <numeric entry> is one of the following:
<signed integer>
<signed real number without exponent>
<signed real number>E<signed exponent>
Example Explanation
“N12001” Enters the five-digit integer 12001
“N-1.23E2” Enters -1.23 x 10
2
“N+154.33E-1” Enters 1.5433 x 10
1
The N command enters numeric values for use with subsequent Put commands. The
interpretation of the numeric value depends on which Put command it is used with.
The E can be used within an N command for entering an exponent of 10. The N can be
used without an E, but an E requires a prior N. The exponent can be any integer from -9
to +9.
The mantissa may exceed 5-1/2 digits. The 8842A accurately calculates the appropriate
exponent and then disregards all but the first 5-1/2 digits of the mantissa. However, a
syntax error will occur if the numeric entry overflows the input buffer.
Example Explanation
“N123456789” Enters +1.23456 x 10

Put Commands
The Put commands P0 and P1 set up the configuration of the Meter and its operating
modes by entering ("putting") information in the appropriate registers. The put
commands are described further in the following paragraphs.
P0 (Put Instrument Configuration)
Format Explanation
N<frst>P0 Where <frst> is a four-digit integer interpreted as
arguments for the F, R, S, and T commands.
Example Explanation
“N3120 P0” Identical to F3 R1 S2 T0. Selects 2-Wire kΩ function,
200 Ω range, fast sample rate, and continuous trigger.
The P0 command allows broadside loading of the Function, Range, Reading Rate, and
Trigger Mode commands (F, R, S, and T). The codes for these commands are listed in
Figure 6.
A numeric entry for P0 must be within +1000 and +6824. Each of the four digits must not
exceed its maximum allowed value (6, 8, 2, and 4, respectively) or an error message will
occur and the instrument configuration will remain unchanged. The entry may be
