10.3.1 Current Calibration Factor

The current calibration factor shows the factor which is used to calculate the displayed block
temperature on the device.

Displayed Block Temperature = Instruments Sensor Temperature x Calibration Factor

To calculate a new calibration factor the instrument uses the following equation.

New Calibration Factor Calculation:

Calibribration = Expected Melting Point

Factor

Please see the following calibration procedure for more details on calibrating the instrument.

10.3.2 Calibration Procedure

The SMP40 allows the user to perform either a single or dual point calibration by using the following
procedure.

1 Using a suitable certified reference material,

perform a melt determination as described in
section 7.

2 If a dual point calibration is required, perform

a second melt determination on a certified
reference material with a different melting
point to that used in step 1.

3 If manual events need to be added to a result

file, they should be added using the steps
described on page 22 before starting the
recalibration procedure below.

4 In the Settings and Calibration screen select

the Manage device calibration section of the
screen.

5 In the Calibration screen press the “Calibrate

this device” button on the Command toolbar.

6 The Set Calibrated Values screen is used to

select the result files that will be used to
calibrate the instrument.

7 Select the first result to be used by pressing the

“Choose Result” field next to Value 1.
