2.2 Electric Safety
Before the first use of the instrument you need to check whether the main voltage is in the allowed
specifications. Operate the dust monitor only with the designated voltage and the original external power
supply.
The Lithium battery (SL-389; 3,6V; 1AH) on the digital circuit board is necessary to the operation
of the real-time clock. This battery must not be charged and only changed in an emptied state by
an authorised personal. The normal operation period is several years.
The recharge of the Lithium battery inside the memory card (CR-2016 with 3V and 60mAh or CR-
2325 with 3 and 200mAh) is not permitted.
Fuses built into the instrument may only be changed by trained service personnel
All fuses are to be replaced only by the same type!
.
Since the instrument has its internal electronic protection, the fuses will react only at a
serious fault!
2.3 Laser safety
Caution! Optical laser class 3 B inside!
The instrument may only be opened by GRIMM trained service personnel. During the opening of the laser
unit, especially the measuring chamber, a laser radiation of the class 3 B can be released. The direct look
into the laser beam or a reflexion can lead to damage of the eyes even at a short exposure time.
You will find references in the EN 60825 (DIN VDE 0837 T1), but also in the corresponding VBG 93
"Laser radiation" prevention regulation for possible accidental exposure!
Caution! Laser class 3B at a open instrument!
