shown on the right.
Saving Changed Values
When you change values, they are saved in the Control’s flash memory (“flash” for short) when the

CAUTION: Before you power down, go to one or more of the screens above and verify your changes.
If you do not use one of these screens before powering down, your changes will not be saved.

HEATING RATE Key
The
HEATING RATE
key brings up the
MANUAL TUNING
screen. This screen
allows you to go to the
SET COARSE HEATING RATE
and
SET FINE HEATING
RATE
capabilities to match the heat generating capability of the thermode to
minimize the temperature overshoot and undershoot.
For example, given a very small peg-tip thermode with a heat generating tip diameter of 0.020 inch
(0.5mm), the
COARSE
heating rate should range from
VERY SLOW
to
SLOW
to prevent severe
temperature overshoot.
Selecting
1
on the
MANUAL TUNING
screen
brings up the
SET COARSE HEATING RATE
screen
.
<SET COARSE HEATING RATE >

Number Select an item, Graph / Data
The progression from
Very Slow
to
Fast
provides more energy to heat the thermode. The table below is
a guide to optimize the coarse heating rate. Change
COARSE HEATING RATE
to optimize temperature
profile output.
