Wait for the display to stabilize before reading the measurement.
For more information about the response times of the sensors, refer to §5.2.3.
3.2. OTHER FUNCTIONS
If 2 sensors are connected to the C.A 1822, it is possible to display the difference between the measurements of the two sen-
sors by pressing the key. The instrument then displays T1-T2 on the upper display unit. A second press restores the display
of T2.
The MAX MIN key can be pressed to monitor the minimum and maximum values. Pressing the xx key a second time causes the
instrument to display the maximum (on both channels in the case of the C.A 1822). After a third press, the instrument displays
the minimum. A fourth press returns it to the current values. To exit from the MAX MIN mode, long-press the MAX MIN key.
On the C.A 1822, when the MAX MIN function is active, the key is deactivated.
