* The thermocouple K probes do not use the SMART PRO system.
TECHNICAL SPECIFICATIONS
* * Performed in laboratories conditions, accuracies mentioned in this document will be guaranteed, subject to the same conditions or to a
calibration balancing.
The VT 300 is a multi-function instrument, compatible with all SMART PRO probes, and with all thermocouple K temperature
probes. The SMART PRO probes are supplied with calibration or adjusting certificate (last calibration date display when
connected). They are automatically recognized when connected, and are fully interchangeable.

Delta T :
When 2 PT100 probes or 2 thermocouple K probes are connected, you have the possibility of calculate
the Delta T which corresponds to the difference between the temperature measured by C1 (or T1) and
C2 (or T2). If 2 PT100 probes and 2 thermocouple K probes are connected at the same time, the screen
shows 2 delta T. To come out of this function, press the touch " ESC ".
Reminder: possible only between 2 probes of identical technology.
Automatic average :
This function allows to calculate the average value that the device measured in an interval of chosen
time. When "Departure" appears on the screen, press on the knob to start the calculation. The screen
registers the sold time. To stop and reach the result, press again on the knob. The results are registered
on the screen: average (s), minimum value (s), maximum value (s), standard deviation(s) as well as the
duration of the calculation. Press on " ESC " to return to the previous page (by pressing on the knob, you
begin a new calculation).
Point / point average :
This function allows to calculate the average value of various points which you will have validated. The
s allows to validate a point or to reach the average of points previously validated. To
validate a point, press on the knob. Validate as many points as necessary, then by means of the knob,
choose "Average" and validate. The screen shows then: average(s), count of validated points, minimum
value(s), maximum value(s) and . To show the values of the various points, press
on the knob. Press then on " ESC ": once to return to the previous display, twice to begin another
calculation and three times to go out of the menu "point / point average".

Automatic point / point average :
This function allows to calculate the average value of various points, calculated themselves on a
duration beforehand defined.
It is necessary to choose at first the duration on which will be calculated each of the points;
and validate every number by pressing on the knob. Once the
duration validated, the scrolling down menu gives you access to the validation of points and to the
average. Proceed then in the same way as for the calculation of "average point / point" (previous
paragraph).
