G) Setting The Automatic Power-Off Time; H) Setting Interface Data Transmission; Taking Measurements - VOLTCRAFT IR 1201-50D Bedienungsanleitung

g) Setting the automatic power-off time

Select the "APO Time" function with "F1" or "F3". The selected function is highlighted with a bar.
Press "F2" to confirm your selection. In the next menu, set the automatic power-off time from 7 to 60 seconds. Change
the setting with "F1" and "F3".
Confirm the setting with "F2" (OK). The display returns to the main menu.
The automatic power-off time starts counting down after the last button is pressed. The automatic power-off function
is not activated in continuous measurement mode.
After powering off, all automatically collected data (current measuring value/Min/Max/Avg/Dif) will be lost.
The pre-programmed system and alarm settings as well as the memory slots (1 - 30) are retained.

h) Setting interface data transmission

Select the "Send Data" function with "F1" or "F3". The selected function is highlighted with a bar.
Press "F2" to confirm your selection. In the next menu, set the transmission mode for real-time data or memory
transmission. Select real-time data transmission (Real Time) or internal memory transmission (Memory) with "F1" and
"F3". Turn this function on and off with "F2"; display shows "On" and "Off".
The activated interface for real-time data transmission is indicated on the display with the USB icon (7H).
Press the "MODE" button: The display returns to the main menu.
The continuous measurement function must be activated for real-time data transmission; otherwise, the
automatic power-off will activate in breaks in measurement.

10. Taking measurements

In order to obtain exact measured values, the infrared thermometer has to be adjusted to the ambient
temperature. Allow the device to adjust to the ambient temperature after relocation.
Prolonged measurement of high temperatures at near measuring distances leads to self-heating of the
measuring device and thus to inaccurate measurements. In order to obtain exact measured values,
remember the following rule of thumb: The higher the temperature, the greater the measuring distance and
the shorter the measuring time.
Shiny surfaces affect the IR measurement results. To compensate, the shiny part of the surface can be
covered with adhesive tape or matt black paint.
The device cannot measure through transparent surfaces such as e.g. glass. Instead, it measures the
surface temperature of the glass.
