Set the IEEE-488 address to a system compatible value as follows:
1. Press .
2. Press  softkey.
3. Press the  softkey.
4. Use the soft keys to set the address as follows.
Select the address digit to adjust by pressing either  or .
With the desired digit selected, press the soft key labeled  to decrement the digit
or  to increment the character.
5. With the desired address set, press .
To set the Meter to Fluke 45 emulation:
1. Press .
2. Press the  softkey.
3. Press the  softkey.
Operating with FlukeView Forms’
When first powered up, FlukeView Forms sends remote commands to the serial port
asking an instrument to identify itself. Because the Meter does not recognize the
commands for the other instruments, an error indication (Syntax error [-102]) is shown on
the Meter’s front panel. This cannot be avoided and is considered normal operation. See
FlukeView Forms documentation for information on setting up that application. When
controlling the Meter with FlukeView Forms, ECHO must be set to NO ECHO and the
Fluke 45 Command language must be selected.
Interconnections
The Meter communicates with a host through a DB-9 interface connector on the rear
panel of the Meter. Connect the Meter to the host or terminal using a cable appropriate to
your application that is less than 50 feet (15 meters) long. Longer cables are permitted,
providing that the load capacitance measured at the interface point (including the signal
terminator) does not exceed 2500 picofarads.
Figure 1 shows the pin-out of the Meter’s RS-232 port, and two possible cable
connections for communicating with a PC.
Fluke 8842A Emulation Mode
The Fluke 8842A emulation mode is only available when the Meter has the IEEE-488
port selected. To change the Meter to Fluke 8842A Emulation Mode, setup the remote
interface for IEEE-488 (Fluke 8842A emulation mode will not work over RS-232 or
Ethernet):
1. Press .
2. Press  softkey.
3. Press the  softkey.
4. Press the  softkey.
Set the IEEE-488 address to a system compatible value as follows:
