Pro)
Select operating temperature on VTF and after clicking temperature control knob, a dashed line (----)
appears on the display
NOTE: while VTF is inserted, it is not possible to set any temperature turning the knob on the instrument.
The plate can heat until the maximum temperature set in the full scale (see chapter 5, "Temp Limt").
It is possible to set the timer only on the VTF.

Screw the threaded support rod into its seat on the back of the instrument
Fasten the clamp onto the support rod
Place the temperature probe in the flask
Plug the probe into the dedicated socket on the back of the instrument
External probe
Switching on the instrument through the main switch, the probe led (A) turns on and display shows OFF
Select operating temperature using the temperature control knob
Click the knob to start heating
The display shows the real temperature obtained by the probe. Each 3 seconds the temperature set point
is shown on the display and the temperature set point led (C) turns on
6. Setting mode
Press both knobs for 3 seconds to enter into the setting mode when heating and stirring are off.
Clicking the Timer/autoreverse button (G) it is possible to pass from one of the following parameter to the next ones:

Description
It limits the maximum value of temperature set point for the heating plate*
(from 50 to 370°C step 10°C)
If "OFF" is set, it is not possible to perform any action with the
temperature control knob
It limits the maximum value of speed set point for the motor (from 100 to
1700rpm, step 100rpm)
Stop: when the instrument is switched on through the main switch, OFF
is visualized on both displays
Run: when the instrument is switched on, it restarts to work with the last
set points set
Fine: slow temperature set point reaching. Overshoot optimized
Fast: fast temperature set point reaching. High overshoot
If "on" it gives AL6 alarm when a slow temperature increase is detected
by the external probe. This function is active in case of:
- Probe temperature < 50°C
T set point – T probe > 5°C
-
If "on" it gives AL7 alarm when a fast temperature decrease is detected
by the external probe.
It allows external probe temperature alignment to a reference
thermometer
Snap: timer countdown starts as soon as one main function
(Temperature/Speed) is on
SetP: timer countdown starts when temperature set point is reached
If "on", stirring continues after timer end
