Scan Rate
The scan rate can be set from 0.1 to 99.9 °C/min. The maximum scan rate, however, is actually limited
by the natural heating or cooling rate of the Product. This rate is often <100 °C/min, especially when
cooling.
The scan rate function appears in the main menu after the scan control function. The scan rate units
are in degrees Celsius per minute, regardless of the selected units.

Set-point Resistance
The set-point resistance is the resistance the Product is trying to make the control sensor achieve and
is calculated in the firmware using the set-point temperature. This value is not directly adjustable but is
recalculated when the set-point temperature is changed. The set-point resistance is used to perform a
calibration adjustment using the Callendar-Van Dusen R versus T curve fit (see
). The Product must be at temperature and stable prior to taking the set-point
resistance reading. The set-point resistance displays by pressing the
SET
and
d
simultaneously. The
set-point resistance is displays as follows:

Secondary Menu
Functions which are used less often are accessed within the secondary menu. The secondary menu is
accessed by pressing

simultaneously and then releasing. The first function in the
secondary menu is the heater power display (see Figure
