Smoothing The Measurement - Chauvin Arnoux C.A 41 Notice De Fonctionnement

Whatever the position of the display:
- one press on HOLD stops the recording without reinitialising the memories.
- one press on MIN MAX for more than 2 seconds cancels the record function.
Note: In normal measurement (without recording, so without RECORD symbol) if, after having pressed
HOLD, the user starts recording by pressing the MIN, MAX button and if the readout ofthe contents of
the MIN or MAX or AVG memories is needed during this HOLD, the display will show three lines ---. The
contents of these memories is not significant because the instruction to record is made during the HOLD
function, which blocks the reinitialisation of these memories.

2.3. SMOOTHING THE MEASUREMENT

A first press on the SMOOTH button triggers smoothing of the measurement (SMOOTH is displayed). The
digital value displayed is then the result of a sliding average calculated over the last 10 measurements
(i.e. approx. 4 seconds).
The bargraph still shws the instantaneous measurement.
A second press on SMOOTH switches OFF the filteing and the SMOOTH symbol goes out. Switching
ON or OFF the SMOOTH mode during a MIN MAX recording cancels the MIN, MAX and AVG values
already stored in the memory.
Note: When the RECORD and SMOOTH symbols are displayed, the smoothed values (MIN, MAX, and
AVG) are recorded with a measurement constant of 4 seconds.
