12. MAINTENANCE OF QE1008-W SENSORS
12.1. Inspection
12.1.1. Foil
To avoid damage on the foil, it should be checked always bevor using the sensor.
Immediately remove any impurities.
12.1.2. Magnet
The surfaces of the magnets are ground and can rusting. They must therefore be
protected by anti-corrosive. To ensure a long service life, we recommend to lubricate the mag-
netic surfaces after use with a paper towel soaked in anti-corrosive. First remove any impurities.
12.1.3. Rechargeable Batteries
Use only rechargeable batteries NiMH, size AAA!
Charging the rechargeable batteries
1. Place the QE1008-W sensors carefully next to each other on a clean surface.
(sensors in the supplied carriyng case stowed are optimally positioned to recharge)
2. Connect the supplied charge bars to the sockets of the sensors
3. Connect the connection cables of the charger to the charge bars.
4. Connect the charger to the power supply (110 - 230VAC).
→ The charging time is approx. 4 hours (the rechargeable batteries can be charged
approx. 1000 times)
