B) Contact Measurement - VOLTCRAFT Ir 1200-50D USB Bedienungsanleitung

To determine the hottest/coldest point of the measured object, guide the measuring opening with the measuring
button (5) pushed over the entire surface of the measured object. The measured value is updated at a rate of
150 ms. Additional functions permit automatic display of maximum value "Max" and minimum value "Min" or
average value "Avg" and difference value "Dif". These values are displayed above and below the main measur-
ing display.
The additional functions "Min" and "Dif" are not available when a contact sensor is connected. The display
shows a sensor temperature "TK" (see contact measurement).

b) Contact measurement

Observe that the contract temperature measurement is only permitted at non-turning and not live objects.
Also observe that contact temperatures are only possible up to the approved sensor temperature. The
approved sensor temperature of the enclosed wire sensor is -20 to +250 °C. To use the entire measuring
range of the meter, you can purchase optional thermocouple sensors of type K.
In addition to contact-free IR measurement, a thermocouple contact sensor type K can be connected as well.
Contact measurement enables measuring the temperature independently of the material and degree of emission of
the object. In addition to the enclosed wire temperature sensor, all conventional type K thermocouple sensors with
miniature plugs can be connected to the device as well.
Sensor connection
Open the lateral cover (1) at the meter.
Plug the thermocouple plug of the sensor into the sensor socket in the correct polarity. Observe the
mark "+" at the plug and the socket. The plug only fits the socket in the correct polarity.
Once a thermocouple is connected to the meter, the display "TK" with the tempera-
ture of the sensor will appear under the IR measured value in measuring operation.
Remove the sensor after the end of the measurement and close the cover to avoid
the ingression of contamination.
The additional functions "Min", "Max", "Avg" and "Dif" are not available for contact measurement. The
information always refers to the IR measurement.
