4.1.5 Tolerance and Sample Size
As with the Standard Programmer, for each program, temperature and humidity stabilisation values can
be defined. Once the chamber conditions are within this tolerance, the step duration timing begins. If
set to zero, no stabilisation criteria are applied and the timing of the step duration begins immediately.
The number of samples recorded in the AutoCal certificate can also be defined from 5 to 50; working
backwards from the end of each set-point duration, values for temperature and humidity are recorded
on the calibration certificate every 2 minutes for the number of samples selected. This determines the
minimum set-point duration above an absolute minimum of 15 minutes.
To change these parameters, click the number next to each one. For example, for Sample Size: (as an
example, in figure 15, the number ‘20’). This will throw up the number entry window:
