SET POINT2: temperature set which the oven reaches with the set gradient and the ongoing launched
ramp procedure, press the
The value of SEt2 must be always higher than SP.

will reach the temperature SP2 from SP with the Heating slope rate selected, starting from the same
temperature as the one with which the ramp has been 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 (item 10.1). The Set Point will change the value
following the selected slope rate.
When the internal temperature reaches the SEt2 set temperature, the internal temperature will decrease
with the cooling slope rate; the SP value will be considered as the new set point value.
During the ramp process, the derivative parameter will not be considered.
During the ramp, the led on the right of the SET POINT flash and the SET POINT increase or decrease the
value.
RAMP PROCEDURE EFFECTIVE EXAMPLE
We suppose to test a thermostat with the expected switch range between 120 and 100°C.
Sp= 100°C
SP2 =120°C
Gradient = 2°C/min.
- Set SP to 100°C using the
- Press the F key and set SP2 to 120°C using the
- Press the F key and set GRD to 2°C/min using the
- Press the F key and set RUN to ON using the
Press the E key to confirm the start of the ramp, the oven temperature will ascend with the heating
slope rate. The temperature will loop continuously between 100 and 120°C until you select run OFF.
Of course, there will be some oscillations at the beginning since the ramp slope will not be suitable but
they will stop in a short time and then the oven temperature will follow the ramp's set point
- SOn
"Switch on" displays the temperature at which the thermostat connected to the terminals "SWITCH TEST"
has closed.
- SOFF
"Switch off" displays the temperature at which the thermostat connected to the terminals "SWITCH
TEST" has open. The values of Son and SOFF will change at each loop or each time you select "run
OFF".
