## Requirements
|
|
|
|
|
|
- Resolution of 0.1 mMED/hr (0.0001 MED/hr)
|
|
|
- (MED/hr is the unit most used by the XP community).
|
|
|
- Display like 199.9 mMED/hr. E.g. a safe indication would be 0.5
|
|
|
mMED/hr.
|
|
|
- Additional symbol (or LED) showing that the level is 0.5 mMED/hr or
|
|
|
lower.
|
|
|
- Allowing an easy indication for small children (smiley, - sign
|
|
|
or other).
|
|
|
- Display on the meter itself (not needing a smartphone for display).
|
|
|
#### The following requirements were agreed on in the Summer camp 2016:
|
|
|
|
|
|
1. Reading like .000 MED/hr (like the existing meter)
|
|
|
2. *Internal* precision in .0001 MED/hr (so that all three digits that
|
|
|
are shown are precise)
|
|
|
3. Calibration precision on .0001 MED/hr internal precision level
|
|
|
4. Display on the meter itself (not needing a smartphone for display).
|
|
|
- Allows easy use, less likely that battery is empty (reduces risk
|
|
|
taking).
|
|
|
- No need for continuous measurement or logging.

- No need for continuous measurement or logging.

|
|
|
#### Features to make it the perfect product:
|
|
|
|
|
|
1. Possibility to show reading in .0001 MED/hr level (may be shown as
|
|
|
00.1 mMED/hr) for calibration and specialist use by internal switch
|
|
|
or any other way, no need to be able to switch easily
|
|
|
2. A happy smiley showing in the display when reading is .000 (don't
|
|
|
care about the non visible digit) This would require a large volume
|
|
|
of custom displays to be purchased.
|
|
|
3. If a smiley is not possible two LEDs that show OK (green), or non OK
|
|
|
(red) (a single LED may bring confusion for red/green colour blind
|
|
|
people).

Currently (2016) the French Enfants de la Lune association is using an
|
|
|
erythema-weighted meter calibrated in MED/hr, which is used as a survey
|
|
|
meter to determine the safety or otherwise of an environment.
