Timer Function; Technical Data; Maintenance And Cleaning - VOLTCRAFT IR-280-4ET Bedienungsanleitung

TIMER FUNCTION

1. Turn the product on using any key.
2. Select the timer function by using the MODE key. The timer icon will be shown in the lower
right corner of the display.
3. The values set last will be shown on the display. When using the timer for the first time,
"00:00:00" will be displayed.
4. Press the SET button. The seconds digits will start flashing. Set the desired value using
the SET key. By pressing and holding the SET key, you can set the desired value quicker.
5. To set the minutes and/or hours digits, press and hold the MODE key for approx. 3 seconds.
The relevant digits start flashing on the display and can now be set as described in step 4.
6. Start the countdown timer with the MEAS key. To turn the timer off before the set time has
elapsed, press the MEAS key again.
After approx. 10 seconds, the display lighting is automatically turned off. The timer keeps
on running and is shown on the display. To deactivate the timer ahead of schedule, first
turn the device on using any key. Then turn off the timer with the MEAS key.
7. When you select another function with the MODE key, the timer icon in the lower right corner
of the display will start flashing.
8. After the set time has elapsed, a continuous beep will sound. Press any key to turn it off.
After approx. 30 seconds the beep sound turns off automatically.
NOTES ON THE MEASURING PROCEDURE
a) Operating principle
• IR thermometers measure the surface temperature of an object. The sensor on the device
records the heat radiation emitted, reflected and transmitted from the object, and converts
this information into a temperature value.
• The emission level is a value used to describe the energy radiation characteristics of a
material. The higher the value, the more capable the material is of emitting radiation. Many
organic materials and surfaces have an emission level of approx. 0.95. Metallic surfaces
or shiny materials have a lower emission level and therefore return inaccurate measured
values.
b) Measurement distance / measurement surface area ratio (D/S)
• To achieve accurate measurements, the target must be larger than the thermometer's
measuring area. The measured temperature is the average temperature of the area
measured.
• The smaller the target, the smaller the measurement distance between thermometer and
target object has to be.
• The distance to target / size of IR focal spot ratio is 4:1. With a distance of 4 cm to the target,
the size of the IR focal spot is thus 1 cm.

MAINTENANCE AND CLEANING

• The device requires no servicing on your part apart from occasional cleaning.
• To clean the surfaces, use a soft, antistatic and lint-free cloth.
• Clean the insertion probe after each use with water.
• Do not use any chemical or abrasive cleaning agents.
DISPOSAL
a) Product
Electronic devices are recyclable waste and must not be disposed of in the household
waste.
At the end of its service life, dispose of the product according to the relevant statutory
regulations.
Remove any inserted (rechargeable) batteries and dispose of them separately from
the product.
b) (Rechargeable) batteries
You as the end user are required by law (Battery Ordinance) to return all used batteries/
rechargeable batteries. Disposing of them in the household waste is prohibited.
Contaminated (rechargeable) batteries are labelled with this symbol to indicate that
disposal in the domestic waste is forbidden. The designations for the heavy metals
involved are: Cd = Cadmium, Hg = Mercury, Pb = Lead (name on (rechargeable)
batteries, e.g. below the trash icon on the left).
Used (rechargeable) batteries can be returned to collection points in your municipality,
our stores or wherever (rechargeable) batteries are sold.
You thus fulfil your statutory obligations and contribute to the protection of the environment.
