RS-232 Print-Only Mode
The print-only mode is used to send measurements to a printer or terminal automatically.
While the Meter will respond to remote commands during print-only operations, Fluke
recommends first setting the Meter's echo mode to OFF. This prevents mixing echoed
command characters and incoming data. Refer to the "Setting Communication
Parameters (RS-232)" section earlier in this chapter.
In the print-only mode, the Meter sends every N-th reading shown on the primary and/or
secondary displays out the RS-232 port, where N is the print rate. The print rate is
selected from the available values described in Table 4-2. The duration between outputs
is determined by the print rate and reading rate of the Meter. The minimum rates are 2.5/s
at slow rate, 20.0/s at medium rate, and 100.0/s at fast rate. The output is formatted as one
measurement per line from the primary display, or two measurements per line from the
primary and secondary displays.
Perform the following procedure to select the print-only mode and to set the print rate
(N):
For frequency measurements, the reading rate is fixed at four readings per
second. The reading rate is always fast for Diode and Continuity tests.

1. Press P to turn the Meter on.
2. Press K. If the RS-232 interface is selected, Print is shown and the list editor is
invoked on the print rate list.
3. Press U or V to scroll to the desired print rate as shown in Table 4-2, and
press and hold R for two seconds to select that rate. (Note that a print rate of
0 disables the print-only mode.) The Meter is now configured for RS-232 print-
only operations. The Meter exits the list editor and returns to normal operation.
