Hold The Digital Value On The Display; Smooth The Measurement - Chauvin Arnoux C.A 41 Mode D'emploi

Notes : - During reading of the MIN, MAX and AVG memories, the recording of new
minimum, maximum and average values is taken into account.
- When the RECORD and SMOOTH symbols are displayed, the smoothed values
are recorded (MIN, MAX and AVG) with a measurement constant of 4 seconds.
- Similarly, when the RECORD and PEAK symbols are displayed, the peak values
are recorded (MIN, MAX and AVG), with a measurement constant of 1 ms.
- In all cases, the analogue display (BARGRAPH) constantly displays the current
measurement with updating of the display every 20 ms.

HOLD THE DIGITAL VALUE ON THE DISPLAY

HOLD
One press on the button allows the user to hold the digital display on the
last measurement displayed whilst the analogue display continues to show the instantaneous
value of the measurement. HOLD is displayed. Pressing
instrument to instantaneous measurement mode and HOLD disappears from the display.
in MIN, MAX and AVG recording mode.
HOLD
When is pressed whilst RECORD is displayed :
HOLD
- HOLD and PAUSE light up.
- recording is stopped and the values contained in the MIN ,MAX and AVG memories
are the last values before
- the digital display shows the value of the last measurement, or even the MIN, MAX
or AVG value if the instrument was displaying these values.
- the analogue display continues to show the current measurement.
Press again to stop recording of MIN, MAX and AVG:
HOLD
- the HOLD and PAUSE symbols go out.
- the digital display shows the current measurement or the contents of MIN, MAX or
AVG memory.
- the instrument is again in MIN, MAX and AVG mode but the memories have not
been reinitialised and they contain the MIN, MAX and AVG values present before
.
HOLD
When the HOLD and RECORD-PAUSE symbols are displayed, it is still possible to display,
successively, the values of the memories and the instantaneous measurement by brief
presses on .
MIN MAX
The bargraph still shows the current value of the measurement.

Whatever the position of the display :

MIN MAX
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
of the 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.
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 shows the instantaneous measurement.
A second press on switches OFF the filtering and the SMOOTH symbol
SMOOTH
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.
