Application Note

7 Fluke Corporation Event recording (or logging) with a Fluke 287/289 Digital Multimeter
Firmware updates to Fluke 287/289 Digital Multimeters
The internal programs of these meters are stored
in flash memory. As a result, Fluke can now offer
product updates and improvements from time
to time.
This sidebar summarizes new additions to the
Fluke 289/287 firmware with version 1.1. Where
applicable, these feature changes have already
been incorporated into the main body of this
application note. The updated firmware may be
downloaded from the Fluke website at www.
fluke.com/software-downloads and installed
using the USB connecting cable furnished with
FlukeView Forms software. Any future firmware
updates for the Fluke 287/289 Digital Multimeters
will include these same features.
Page numbers () are indicated to help you
locate details of these features in the updated
user manual available online in pdf format at
www.fluke.com/289-manual.
Recording and display (TrendCapture)
1. Basic settings for a recording session have
been simplified and clarified. (53-54)
Recording setup is accessed using the Save-
Record soft-keys. In the Recording Menu, you
now select only Duration of recording and
Sample Interval. Percentage of available mem-
ory and battery condition are reported.
2. Event Threshold Value (%) for AutoHOLD and
Recording can now be set in the meter. (54)
Previously, it was necessary to make this set-
ting using FlukeView Forms software from a
connected computer. (Default values are 4 %
for both functions.) Threshold value setup is
accessed using the Setup-Recording soft-keys.
On the Recording Setup screen, you may now
select Event Threshold to adjust the AutoHOLD
threshold value and adjust using the cursor
keys for values between 1 % and 30 %. Event
Threshold for Recording may be turned off, if
only interval recording is desired, or set to one of
seven selected values between 1 % and 25 %.
3. The TrendCapture graphic display of events
recorded by the meter has been improved to
more clearly indicate the activity of a device
being recorded. No change in user operation is
required to make use of this improved display.
4. A new Zoom feature has been added to the
Trend Data display that expands the graph to
show more details of unusual events (51)
To use this new feature, first position the
vertical cursor bar over the point of interest
in the Trend Data display (using the left and
right arrows) and then press the up arrow to
magnify the display by two, centered on the
cursor position. You can do this repeatedly until
the desired resolution is achieved. Zoom back
out by using the down arrow. Date and time
are reported above the graph along with the
zoom level (full display is x1). The recorded
value at the cursor position and the time it was
recorded are reported under the graph.
Other features, additions, and updates
1. When switching to the current measurement
functions (A/mA or uA) the meter will ‘remem-
ber’ the last used selection for ac or dc. (39)
Once in this function, the same setting will
hold between A, mA and uA. This feature is
useful when the operator is using ac only or
ac+dc current clamp accessories, to minimize
repeat setup actions.
2. A Smoothing mode may be enabled for ac
measurements. (49)
This feature allows you to select a filter to
smooth noisy ac readings. Smoothing options
are accessed using the Setup-Instrument
soft-keys. Under Edit, you can then turn the
smoothing function on or off using up-down
arrow keys.
3. You can add your name, company name,
worksite, and contact information under
Setup-Meter Info (49)
This information can only be added using
FlukeView Forms software while the meter is
connected to your computer.
4. Changing file names.(49)
When saving a measurement, min/max, peak
min/max, or recording session, the meter
selects one of eight possible Save Names with
an auto incrementing number. The user can
now use Fluke View Forms to change the Save
Names to something more meaningful.
