measured value appears on the display:
MAX: Highest measured value of the last measurement.
MIN: Lowest measured value of the last measurement.
AVG: Average value of the last measurement.
DIF: Difference between highest and lowest measured value of the last measurement.
These values always refer to IR measurement, not to contact measurement.
g) Bar graph
• The bar graph can be used to graphically view the current measured value in relation to the
MIN/MAX values. The left end represents the MIN value of the current measurement, the
right end the MAX value.
• Example: The MIN value is 0 °C and the MAX value +100 °C. The current measurement is
+50 °C. In this case the bar graph deflects to the middle of the display.
