Switch test
1. With the [▲] or [▼] button, select ON or OFF.
2. With the [E] button, start or stop the switch test.
The temperature dry-well calibrator reaches temperature SP2 from SP with the selected heating rate of
change. The basis is the same temperature with which the ramp was confirmed. If the value of SP2 is lower
than the SP, the calibrator will not accept the run and the instrument will display "Err". The LED will flash to
indicate that the function is active. The set point will change the value following the selected slope rate. When
the internal temperature reaches the SEt2 set point, the internal temperature will decrease with the cooling
slope rate; the SP value will be considered as the new set point. During the ramp program, the derivative
parameter will not be considered. During the ramp program, the LED on the right of the set point flashes and
the set point increases or decreases the value.
20
The value of SEt2 must be always higher than SP.
The gradient must be smaller than the maximum specified value in the technical specifications (max.
15 °C/min).
