6. OPERATING ENVIRONMENT :
Operating temperature : 32ºF to 102.2ºF (0ºC to 36ºC) within still
air and hard smooth target surface for
accurate measurement.
7. NOTES :
t
When measuring between 40' to 50' / 12m to 15m, the relative
humidity should be above 50% and target area at least
10ft.
´
10ft. (3m
´
3m)
t
Inaccurate measurement may result from the following :
1) When the battery runs out.
2) When the measured distance is out of the specified range
(1'8" to 50' / 0.5 to 15m).
3) Interference of another ultrasonic source when nearby.
4) When the unit is not held straight and perpendicularly to the
target.
5) Long narrow corridor.
6) Irregular objects near the target.
7) The reflected ultrasonic pulse from the target is narrow.
t
An error message "Err" will be displayed on screen under
following conditions :
1) When the measured distance or calculation result exceeded
the specified range.
2) When the unit is held wide angle to the target.
3) The target surface does not provide good reflection for
ultrasonic pulse. (i.e. soft and irregular surface such as thick
carpet, curtain or irregular wall paper, walls etc.)
t
This product would lose temporal memory and reset
automatically under a strong electro-static environment.
