6. Ensure the Meter’s RS-232 port is set to 9600 Baud, No parity, and Echo Off using
the instructions found in the Configuring the RS-232 Port section of Chapter 3 Users
Manual.
7. Follow the instructions for transferring data from the Meter to the PC, found in the
online FlukeView Forms Users Manual.
FLUKE 8842A Emulation Mode
The Fluke 8842A emulation mode is only available through the GPIB interface.
Whenever the 8846A or 8845A has the RS-232 or LAN interface selected, 8842A
emulation mode is not selectable through the front panel.
The 8842A IEEE-488 commands are listed in the following tables. These commands are
identical, except where indicated. For operational differences and commands that are not
supported in the 8845A or 8846A, refer to Appendix D.
Example Notes
In the examples in this manual, device-dependent commands are shown enclosed within
quotation marks, as they would be entered in Fluke BASIC. For clarity, the commands
are also separated by spaces. However, the spaces are are not necessary and may be
omitted.
Example Explanation
“* F3 R1 S1 T2” This example is equivalent to “*F3R1S1T2” or
“*,F3,R1,S1,T2”.
Using the Fluke 1722A Instrument Controller, these commands might be written into a
BASIC program as shown in Figure 5. Examples using other controllers are given at the
end of this section.
Here is a typical command string as it might be sent from a Fluke 1722A Instrument Controller. The
string configures the meter and triggers a reading. The PRINT command automatically sends
terminators (CR, LF, and/or EOI) to the meter at the end of the command string.
PRINT @3, “* F3 R4 S1 T2 ?”
IEEE-488 bus address
Resets the meter to the
power-up configuration

Figure 5. Typical Command String for 8842A Emulation
Examples of 8842A emulation output data show the terminators CR and LF. The
terminator EOI is not shown because it is a uniline message. However, the terminators
CR, LF, and EOI are all selectable using the Write commands.
