7.3 Descrip�on of the menus
The calibrator has 4 menu levels.
1st. level: Func�ons for the con�nuous usage
2nd. level: More specific func�ons for the regula�on of the calibrator
3rd. level: Func�ons for re-calibra�on of the device
4th. level: Procedures to set the max. temperature thermostat
1st. menu level

Temperature set which the calibrator has to reach following its technical specifica�on.

ramp procedure, press the

GRD Gradient
Speed of change in temperature when passing from the SP value to the SET2 value and vice
versa. Press the
ramp from SET2 to SP the gradient value must be nega�ve.
NOTE: gradient value to be set at point 2 must be lower than the ones stated in the
technical data (Cooling gradient max -7°C/min, hea�ng grad. max. 18°C/min).
RUN Switch test process.
Select ON or OFF by the
The calibrator will reach the temperature SET2 from SP with the hea�ng slope rate
selected, star�ng from the same temperature as the one with which the ramp has been
confirmed. If the value of SET2 is lower than the SP the GRD value must be set with the
minus sign "-", otherwise the calibrator will not accept the run and the display shows „Err".
When the ramp is ac�ve, ramp icon will flash on the display. 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
deriva�ve parameter will not be considered. During the ramp, the ramp icon on the right
of the SET POINT flashes and the SET POINT increases or decreases the value.
EXAMPLE:
We suppose to test a thermostat with expected switch range between 100°C and 120°C.
Sp = 100°C
SET2 = 120°C
Gradient = 2°C/min
Follow the instruc�ons for this example on next page.
