MAX value
Similarly, a measurement higher than the value contained in the MAX register will cause it to
be updated. Each time the contents of the MAX register is modied, a beep is emitted.
AVERAGE value
Initially, the average value corresponds to the value displayed when MIN MAX is rst pressed.
Every second the instrument inputs the digital measurement, then it takes the sum of all the
values input since the beginning of the record command and divides the whole by the number
of seconds that have gone by. The result (the average value) is transferred to the AVG register.*
Thus the contents of the AVG register are updated every second. This average value can be
assimilated to the average dose of elds measured over a given period (dosemeter function).
The duration of AVG is shown on the clock display as HH MM.
* AVG: abbreviation of AVERAGE.
Reading MAX, MIN and AVG values
The display of the values contained in the MAX, MIN and AVG registers is done by successive
presses on MIN MAX.
The cycle of the display successively indicates the maximum value reached (MAX symbol),
the minimum value reached (MIN symbol), the average value (AVG symbol) then the value of
the current measurement and so forth.
The time of the recording is specied for the maximum and minimum values. The duration of
averaging ∆t is specied for the average value (AVG). If this duration is greater than 24 hours,
OL* is displayed.
Cancelling the MIN, MAX and AVG functions
The MIN, MAX and AVG recording functions are switched Off by pressing MIN MAX for more
than two seconds.
Notes:
- On the MIN MAX function, Auto Off is automatically cancelled ( symbol displayed).
- Switching On or Off SMOOTH and PEAK modes during a MIN MAX recording erases the MIN, MAX
and AVG vaues already stored.
- During the reading of the MIN, MAX and AVG memories, the recording of new minimum, maximum and
average values is taken into account. It is impossible to memorise them manually: pressing MEM only
displays the remaining memory capacity.
- 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
update of the display every 20ms.
HOLD function on MIN, MAX and AVG recording mode
When HOLD is pressed with RECORD displayed:
- HOLD and PAUSE light up.
- The recording is stopped and the values contained in the MIN, MAX and AVG registers are
the last values before HOLD.
- The digital display indicates the value of the last measurement, or, the MIN, MAX or AVG
value if the instrument is reading these values.
- The analogue display continues to indicates the current measurement.
