basic stamp contol of potentiometer

Hello group,
I am very new to the whole idea of basic stamps and their aplications.
I am in the initial stages of developing a project and I am looking
for some information.
Here is a brief explanation of what I am trying to do:
I have a test console that is used to test electrical meters and I
am trying to stabilize my load. When testing meters a pre-determined
load is calculated. The power supply has both voltage and current
rheostats with independent loading transformers. The unit also has a
voltage and current regulator and the current regulator is
controllabe with a controller. The unit has a standard (Radian) with
a pulse output. When the load is set the rheostats are adjusted
accordinly and then the controller is activated and the load is again
set using two potentiometers. The load is monitored using a pc and
counting pulses from the output of the Radian. The tests are run for
a duration of 45 minutes and the load will continually drift. We
require the board to hold the load at 0.2% regulation and it is more
like 0.5% reg.. The monitoring program we use displays the load (in
watts) every one minute. As we notice the load drifting we have to
constantly adjust the pot. to reset to the desired load. What I am
looking at is developing a program that monitors the load every ten
seconds (or less) and then contiually adjusts the pots to do this.
Would this be possible using a basic stamp with a digital controlled
pot. ?
Any advice would be truly appreciated.
Regards,
Dennis

up to about 10 volts at a few milliwatts. From your description, it
sounds like your potentiometers might have to handle much more
voltage and power than that. Maybe not? One alternative would be
servos to control your pots mechanically.
