Technical Specification - Sthor 81713 Bedienungsanleitung

PRODUCT OVERVIEW
The meter is used to measure the light intensity. The meter also measures the ambient temperature.
The measurement result is presented on the LCD. The product is battery powered and its small di-
mensions and light weight ensure high mobility.
Before using the product, read the entire instructions manual and keep it for future reference.
CAUTION! This product is not a measuring instrument within the meaning of the Trade Metrology Act.

SAFETY INSTRUCTIONS
The product is not waterproof and should always be kept dry. Do not expose to precipitation. Do not
immerse in water or other liquids.
If the product is not used to measure light, always cover the light sensor with the guard provided
with the meter. Damage to the light sensor guard may aff ect the light intensity measurement result.
Always replace batteries in pairs. The utilisation of used and new batteries to supply the device will
result in its shorter operating time and can also lead to leakage of electrolyte from the battery. Be sure
to maintain proper polarity when replacing batteries. In case of storage of the product for an extended
time (over one month), remove the batteries from the product.
The device can also be powered by Ni-MH batteries. In this case a shorter operating time of the device
should be taken into account.
If the product has been stored in conditions beyond the operating conditions, wait until the product
reaches the operating conditions automatically before use.
The product is not intended to be operated by children. Make sure that children do not treat the
product as a toy.
PRODUCT OPERATION
Installing and replacing the batteries
Open the battery compartment cover. If batteries are already installed in the compartment, remove
them. Install new batteries observing the correct polarity. Replace the battery compartment cover. It is
recommended to use good quality alkaline batteries.
Operating the device
Press the power switch, the meter will turn on and all symbols will be visible on the display for ap-
prox. 1 second. Next, the meter will automatically measure the light intensity and temperature. The
measurement result will be shown on the display and will change according to the light intensity and
temperature in the vicinity of the meter. The upper row of the display shows the light intensity value
and the lower row – the ambient temperature.
Another pressing of the power switch will turn on the display backlight. The display backlight will be
turned off after pressing the power switch again.
Pressing and holding the power switch for approx. 2 seconds will result in turning off the meter. To
reduce battery consumption, the meter will turn off automatically after approx. 15 minutes from the
last pressing of the button. If the power switch will be pressed and held during the device start-up, this
will result in displaying the NO indication on the display. In this mode, the meter will not turn off auto-
matically and will continue to run until the battery will run out or the device will be turned off manually.
Turning the meter off and on will cause the meter to operate in the automatic turn-off mode. The meter
operating in the automatic turn-off mode has a clock indicator visible on the display.
The light intensity measurement result can be supplemented with a multiplier mark (X10, X100,
X1000) – this indicates by what number the result shown on the display should be multiplied to obtain
