Reading The Max/Min/Avg/Dif Value; Measurement Parameters - Chauvin Arnoux C.A 1860 Notice De Fonctionnement

In the case of small measurement points, it is important bring
the sensor rather close to the target to avoid including other
points in the measurement field.
4.4. READING THE MAX/MIN/AVG/DIF
VALUE
Press the MODE key repeatedly to cycle through the MAX/
MIN/AVG/DIF modes. The temperature corresponding to
the mode will be displayed on the secondary display (as in
the figure below).
„ MAX mode
Following a long press on the trigger, the secondary display
unit indicates the maximum value of the temperature mea-
sured during the trigger press.
„ MIN mode
Following a long press on the trigger, the secondary display
unit indicates the minimum value of the temperature measured
during the trigger press.
„ AVG mode
Following a long press on the trigger, the secondary display
unit indicates the mean value of the temperature measured
during the trigger press.
„ DIF mode
Following a long press on the trigger, the secondary display
unit indicates the temperature difference between the MIN
and the MAX during the trigger press.
