<font face="Arial">Congra<font face="Arial">tulations! Any tim<font

face="Arial"> list of the living it is a<font face="Arial">
major accomplishment.<br>
<br>
<font face="Arial">On the subject of g<font face="Arial">auge
calibration, etc, I would suggest you read Stu<font
face="Arial"> Bren<font face="Arial">nan's article
on Tigers United.<br>
<a

face="Arial"> if you haven't already.<br>
<br>
<font face="Arial">Based on the article, it is
clear that when t<font face="Arial">he <font
face="Arial">temp<font face="Arial">eratu<font
face="Arial">re gauge is reading too
high, as in your ca<font
face="Arial">se,<br>
<font face="Arial">it can be
corrected in a fairly
straightforward way without <font
face="Arial">t<font
face="Arial">he expense of <font
face="Arial">getting it
recalibr<font face="Arial">ated<font
face="Arial">.<br>
<font face="Arial">From
Stu's article, it
can be seen that a
high reading is
caused by a low res<font
face="Arial">istance
of the gauge. What<br>
<font face="Arial">I
did to correct
the situation
was to first ob<font
face="Arial">tain
a variable
resistor (<font
face="Arial">a
pot, or
potenti<font
face="Arial">ometer)
and place<br>
<font
face="Arial">it
in series with
the gauge. You
will see,
then, as you
increase the
resistanc</font>e
of the pot,
the gauge
reading<br>
<font
face="Arial">will
fall. By
taking the ac<font
face="Arial">tual
temperature
with <font
face="Arial">your
ir thermome<font
face="Arial">ter,
you can adjust
the <font
face="Arial">pot
so that the<br>
<font
face="Arial">reading
of the gauge
agrees with
your thermome<font
face="Arial">ter.
You can the<font
face="Arial">n
<font
face="Arial">use
a multimeter
to read the
actual <br>
<font
face="Arial">resi<font
face="Arial">stance
of the<font
face="Arial">
pot and
replace the
pot with a
fixed resistor
of about the
matching
value. I did
this <br>
<font
face="Arial">several
years ago and
it has proven
to be a
permanent fix
si<font
face="Arial">nce
I have
occasionally
checked the
calibration<br>
<font
face="Arial">with
my ir
thermometer.<br>
<br>
<font
face="Arial">As
far as the
prob<font
face="Arial">lem
with the tach,
my suggest<font
face="Arial">ion
is that you
send<font
face="Arial">
the tach to
Tom Hall and
have him<br>
<font
face="Arial">do
the solid
state convers<font
face="Arial">ion.
It's the best
solution IMHO
and it<font
face="Arial">'s
essentially
permanent.<br>
