Contact Measurement; Settings; Emission Level - VOLTCRAFT IR 800-20C Bedienungsanleitung

h) Contact measurement
Contact temperature measurement is permissible in combination with non-rotating
and voltage-free stationary objects only.
Contact temperatures are only possible up to the approved temperature of the sensor.
The approved temperature range of the included wire sensor is -20 to +250 °C.
In order to use the entire measuring range of the measuring device, you need an
optional wire sensor with a higher maximum temperature.
Contact measurement allows for measurement of temperature regardless of the
object's material and emission level.
In addition to the included wire temperature sensor, all conventional K-type
thermocouple sensors with miniature plug be connected to the device.
• Open the cover to expose the sensor socket.
• Plug the thermocouple plug of the sensor with correct polarity into the sensor socket. Pay
attention to the "+" marking on the plug and the socket. The plug fits only in one direction
into the socket.
• As soon as a sensor is connected to the measuring device, the temperature of the sensor
appears below the IR measured value in measuring mode.
• After measuring, remove the sensor and close the cover to prevent dirt from entering the
device.

11. Settings

a) Emission level
The measuring device allows setting the emission ratio. Thus, different materials and surfaces
can be measured with exact results.
• Hold the MODE button for approx. 1 second to access the setup menu. The symbol for the
emission level flashes.
• Press the ▲ or ▼ button to change the value. Press and hold the button for fast setting.
• Press the measuring button to confirm your input or press the MODE button to proceed to
the next setting.
• When the device is switched off, the set value is retained.
