OPTICAL AND ACOUSTIC SIGNALS
If you want to check certain measured values regularly, you can select a reference temperature in advance and set tolerance limits of 1 °C, 3 °C or 5 °C. If the measured temperature value lies outside the limit corridor, this is indicated by a colored display and an acoustic signal.

Green for tolerance value
You have specified a reference value of 25 °C and set a threshold value of 1 °C. If the measured surface temperature is between 24 °C and 26 °C – i.e. within the tolerance range – the display lights up green.

Blue for underrun
The reference value is preset to 20 °C and the selected tolerance limit is +/- 3 °C. So if the measured temperature was between 17 °C and 23 °C, everything would be fine. However, if the measured value is below 17 °C, the display will light up blue and you will also hear a signal at long intervals.

Red when exceeded
The reference value is 30 °C and the sensitivity level is 5 °C. Thus, a measured temperature between 25 °C and 35 °C is within the tolerance range. If, however, the surface temperature of the measured material is above the maximum value of 35 °C, the display lights up red and an acoustic signal sounds at short intervals. With the BP17, you can see directly at all times whether your specified temperature range is being maintained without having to pay attention to the exact values.
