UHP Calibration Instructions
6.
Use the instrument Head UP and Head DOWN buttons to position the heat
flow sensor between the Peltier plate and the geometry as shown in Figure
7.21.

When the calibration is finished, raise the instrument head, and remove the calibration sensor. Remove the
connector from the electronics box.
NOTE: For safety reasons the temperature control is set to idle at the end of the calibration
routine, although the final temperature will still be displayed as the set temperature.

5. When the zero value calibration has been completed
a window, similar to that shown in Figure 7.16, will be
displayed. Follow the instructions given. The zero heat
flow sensor is shown connected to the calibration box in
Figure 7.20 below.

Calibration Box (Note the T on the
upperside of the sensor.)
7. Click Next to begin
calibrating as instructed
(see Figure 7.19, above
left). When the calibra-
tion is complete the
results will be displayed
as shown in Figure 7.22
(to the left).
The graph shows the
temperature difference
between the set tempera-
ture and the temperature
read by the Upper
Heated Plate heat
spreader probe, plotted
against set temperature.
The Gradient calibration span is the slope of the best-
fit straight line through the data, and the Gradient
calibration offset is the intercept.
8. To accept the values click Next. The instrument
firmware will automatically be updated with these
values.
