VOLTCRAFT IR 1000-30D Bedienungsanleitung Seite 28

Setting the emissivity (EMS):
The measuring device is equipped with an emissivity setting. This allows you to obtain more accurate
results for different materials and surfaces (also see "Operating principle").
- Press the measuring button (5) to switch on the measuring device.
- Press the "Mode" button (6) until the emissivity symbol (20) flashes in the display.
- Use the "up" (4) and "down" buttons (7) to adjust the emissivity to a value between 0.10
and 1.00 for the object to be measured.
- Press the measuring button (5) to confirm your changes, or press the "Mode" button (6)
to move on to the next setting option.
- Your changes remain saved when the device is switched off.
See the table following the specifications in these operating instruction for common materi-
als and their corresponding emissivities.
Many organic materials have an emissivity of 0.95. Therefore, the factory emissivity setting
is 0.95. The emissivity of a surface may also be determined by the contact temperature
measurement function of the device. Measure the surface temperature with the contact
temperature measuring function. Change the infrared thermometer's emissivity until the
measured value (24) corresponds to the value of the contact measurement function. To
achieve the most accurate values with the contact temperature measurement function, a
special K type surface temperature sensor is recommended (can be included optionally).
However, this is only required for extremely precise measurements.
Continuous measurement (LOCK)
The measuring device is equipped with a continuous measurement function for long-term measurement.
- Press the measuring button (5) to switch on the measuring device.
- Press the "Mode" button (6) until the continuous measurement symbol (16) flashes in
the display.
- Activate the continuous measurement function with the "up" (4) and "down" (7) buttons
(display "ON")..
- If you now press the measuring button (5), the continuous measuring function will be
activated. The measuring device now measures continuously until the measuring button
(5) is pressed again.
Alarm functions
The measuring device has an alarm function to notify you when the measured
value is not within a set temperature range. The alarm is given by a beeper.
This function makes the measuring device perfect for temperature checks etc.
Two temperature values can be set in the device (high and low alarm value).
The alarm is triggered when the temperature is below the low alarm value or
above the high one. The alarm values may be set and activated independent-
ly of each other.
