6.4 Operation

 

Consult an expert when in doubt about the operation, safety or connection of the appliance.

 

If it is no longer possible to operate the product safely, take it out of operation and protect 

it from any accidental use. DO NOT attempt to repair the product yourself. Safe operation 

can no longer be guaranteed if the product:

 

– is visibly damaged,

 

– is no longer working properly,

 

– has been stored for extended periods in poor ambient conditions or

 

– has been subjected to any serious transport-related stresses.

6.5 (Rechargeable) batteries

 

Correct polarity must be observed while inserting the (rechargeable) batteries.

 

The (rechargeable) batteries should be removed from the device if it is not used for a long 

period of time to avoid damage through leaking. Leaking or damaged (rechargeable) bat-

teries might cause acid burns when in contact with skin, therefore use suitable protective 

gloves to handle corrupted (rechargeable) batteries.

 

(Rechargeable) batteries must be kept out of reach of children. Do not leave (rechargeable) 

batteries lying around, as there is risk, that children or pets swallow them.

 

All (rechargeable) batteries should be replaced at the same time. Mixing old and new (re-

chargeable) batteries in the device can lead to (rechargeable) battery leakage and device 

damage.

 

(Rechargeable) batteries must not be dismantled, short-circuited or thrown into fire. Never 

recharge nonrechargeable batteries. There is a risk of explosion!

6.6 Laser

 

When operating the laser equipment, always make sure that the laser beam is directed so 

that no one is in the projection area and that unintentionally reflected beams (e.g., from 

reflective objects) cannot be directed into areas where people are present.

 

Laser radiation can be dangerous, if the laser beam or its reflection enters unprotected 

eyes. Therefore, before using the laser equipment, familiarise yourself with the statutory 

regulations and instructions for operating such a laser device.

 

Never look into the laser beam and never point it at people or animals. Laser radiation can 

seriously damage your eyes.

 

If laser radiation enters your eyes, close your eyes immediately and move your head away 

from the beam.

 

If your eyes have been irritated by laser radiation, do not continue to carry out tasks with 

safety implications, such as working with machines, working from great heights or close to 

high voltage. Also, do not operate any vehicles until the irritation has completely subsided. 

 

Do not point the laser beam at mirrors or other reflective surfaces. The uncontrolled, re

-

flected beam may strike people or animals.

 

Never open the device. Setting or maintenance tasks must only be executed by a trained 

specialist familiar with potential hazards. Improperly executed adjustments might result in 

dangerous laser radiation. 

 

The product is equipped with a class 2 laser. Laser signs in different languages are in-

cluded in the package. If the sign on the laser is not written in the language of your country, 

please affix the appropriate sign onto the laser.

 

 

Caution: if operation settings or procedures other than those described in these instructions 

are used, it could lead to exposure to dangerous radiation.

 Operating Instructions

Laser Revolution Counter DT-10L

Item No. 122624

1 Intended use

This measuring equipment is an optical rev counter with a precise measuring laser for use in 

private and commercial fields. The measurement is carried out via reflection. Self-adhesive 

reflective markers are provided and can be fixed to revolving objects. The rev counter emits a 

red laser beam which is reflected by the reflective marker. A photo diode inside the rev counter 

records the reflected laser light and analyses it. Due to the precise laser beam even small ob

-

jects with a large clearance of 5 to 50 cm can be measured. The measured values can be read 

in RPM (Revolutions Per Minute) in the 5-digit-display or as an event (incremental counter).
The appliance can be operated with a 9 V battery or with an optional mains supply adapter of 

9 V/DC output voltage.
If you use the product for purposes other than those described above, the product may be 

damaged. Beyond this there is the risk of injuries, e.g. to the eyes.
The product complies with the statutory national and European requirements. For safety and 

approval purposes, you must not rebuild and/or modify the product.
Read the operating instructions carefully and store them in a safe place. Make this product 

available to third parties only together with the operating instructions.
