2. Why this project?
To investigate the resources needed to
create an application for Palm compatible
PDA (Personal Digital Assistant).
Why was this project chosen?
3. Why this project?
Devices with the Palm OS hold
approximately 70% of the PDA market
share.
Why the Palm Device Specifically?
4. What is FlukePad?
A PalmPilot application that will allow a
user to view stored event data from a
Fluke89-IV DMM (Digital Multi-Meter).
5. What data exactly?
Event data!
Event Data is different then saved data. Saved data is
stored one piece at a time, and can be multiple types,
such as: two readings in volts, three in Farads, etc.
Event data is logged automatically after being started by
the user. The data is all of the same type (I.e. all DC
Voltage, or All Resistance, etc).
This is the data my software works with.
6. What can it do?
Communicate with a Fluke 89
FlukePad uses the built in IR port on the Palm IIIxe to
communicate with the IR port on the Fluke 89-IV.
7. What can it do?
Graph logged data
- Auto Scales to allow easy interpolation
- Adds 20% to view to help minimize
zooming in on noise
8. Why zoom out 20%?
Same Data with and with 20% zoom
out
With 20% Without 20%
9. What can it do?
Store data for later use
-Stores all data received from the meter in
a database
This feature will be useful if a version is
created that uploads data to Fluke View
Forms.
10. What can it do?
Display the information on individual
events.
11. What can it do?
Display the information on individual
events.
When the pen touches the screen,
FlukePad calculate what even the
user has selected, and displays it.
Due to the low resolution the is
sometimes multiple events.
12. What can it do?
Display the information on individual
events.
A user can see individual records by
pressing the up or down hard keys on
the palm.

15. How much space does it
take on a PalmPilot?
The Application is approximately 20K
The Database Ranges from
98 bytes (just the database header)
40K (995 records)
16. What features still need to
be added?
Support for multiple databases
The Ability to send data to Fluke View
Forms
17. What problems came up
during this project?
The Fluke 189 does not have IrDA
compatible hardware, and will not directly
interface with the PalmPilot.
The current software is only compatible
with Palm OS 3.5 and greater. (I.e.
currently no Handspring Visor support,or
older palms that do not have FLASH
RAM)
18. What is this IrDA stuff?
IrDA stands for Infrared Data Association
IrDA is a standard for Infrared
communications.
The 189 Meter doesn’t needs IrDA to
communicate with Fluke View Forms. This
hardware change saves about $2.00 a
meter.
19. Does this mean the 189
can’t be used?
Not necessarily. Fluke View Forms uses
an IR cable, with the proper adapter this
could be used off the serial port on the
Palm. There are also Ir adapter for the
Palm that could be adapted
20. Who Cares?
The customers!
What additional feature would you like to
see in the next multimeter your purchase?
“ The capability to download data logged
info straight to a palm pilot hand held
computer”
