A) Ir Measurement; B) Contact Measurement; Sensor Connection - VOLTCRAFT IR 1201-50D Bedienungsanleitung

a) IR measurement

Point the laser outlet (9) at the object to be measured at a 90° angle. Make sure the object
to be measured is not smaller than the IR measuring surface of the device.
Press and hold the measuring button (5). The measured value (B) is shown in the
display. The displayed value corresponds with the average surface temperature of the
IR measuring surface. "SCAN" (D) appears on the display while the temperature is being
measured. If the temperature measuring range is exceeded, "----" is displayed.
After releasing the measuring button (5), the last measured value is displayed until the
product powers off automatically. "Hold" (D) is also displayed.
After releasing the measuring button (5), the device switches off automatically when the
preset time elapses.
To determine the warmest/coldest spot on the object to be measured, pass the laser outlet over the entire
surface area of the object while holding the measuring button (5). Additional functions allow the automatic
display of the maximum value and minimum value "Min" or "Max", average value "Avg" and the difference
value "Dif". These values are displayed above and below the main measurement display.
The additional functions "Min" and "Dif" are not available when a contact sensor is connected. The display
shows the sensor temperature "TK" here.

b) 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 permitted temperature of the included wire sensor is -20 to +250 °C. In order to take advantage
of the entire measuring range of the measuring device, an optional wire sensor with a higher maximum
temperature is required.
In addition to contactless IR measurement, a type-K thermocouple contact sensor may also be attached to the device.
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.

Sensor connection

Open the side cover (1) on the device.
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 thermal sensor is connected with the measuring device, in measuring mode
the display shows "TK" with the temperature of the sensor beneath the IR measuring value.
After measuring, remove the sensor and close the cover to prevent dirt from entering the
device.
The additional functions "Min", "Max", "Avg" and "Dif" are not possible with
contact measurement. These values pertain to IR measurements only.
