SV 104BIS MAINTENANCE
7.1 G
ENERAL RECOMMENDATIONS FOR USE
•
Do not disassemble or modify the instrument. The battery inside contains safety and protective
devices, which, if damaged, may cause the battery to generate heat, explode or ignite.
•
It is not recommended to leave the instrument nor accessories in direct sunlight conditions for
prolonged periods of time. Doing so may cause the battery contained inside to generate heat,
explode, or ignite. Using the instrument in this manner may also result in a loss of performance
and a shortened life expectancy.
•
Do not keep the instrument for a long time discharged (see Chapter 7.7 ).
•
Charge the SV 104BIS instrument in a docking station before attempting to turn it on if the
dosimeter has not been used for a prolonged period or was stored in a low battery state
condition.
•
To improve accuracy of remaining battery life indicator, run the dosimeter until it is fully
discharged; then proceed with a full charge with use of the
SB 104B-5 or SB 104B-1 docking
station. The procedure is recommended before first use. Repeat this procedure year of use
to maintain more accurate current battery condition indication.
•
Use docking station charger only in a safe area.
7.2 C
LEANING
Few things to remember:
•
Every time SV 104BIS gets too dirty, clean the surface of the dosimeter with water damp soft
cloth. Under no circumstances should this equipment be cleaned using a solvent based cleaner
(it can affect the case polymeric materials).
•
Pay special attention that the provided
SA 122BIS
windscreen is clean because dirtiness can
affect the measurements. Take off the windscreen, shake off any dirt, and clean it with damp
cloth. If necessary, change the windscreen to a new one. The foam windscreen is considered
a consumable item and will need replacing if it becomes lost or its condition deteriorates too
much. Packs of 3 replacement windscreens are available under the part number
SA 122BIS_3.
•
Pay special attention that the microphone front part is clean because dirtiness can affect the
measurements. Avoid the small inlet hole getting too dirty. Clean carefully with a dry and soft
non-fraying cloth.
7.3 I
N SITU CALIBRATION
It is advised to perform an acoustic calibration of the instrument each time before and after the measurement
run. A single calibration at the start of each day of use is usually sufficient for most regulations. See Chapter
4.7
for calibration details.
Note: With the use of the SV 34B calibrator the calibration can be performed only in a safe area.
