  For every 10Ω of line resistance, the compensating cable will indicate a temperature 0.12°C higher than actual. Please check the line resistance before installation. Long compensating cables are more prone to noise interference, shorter (less than 100m) compensating cable is recommended.

  The time of A/D conversion is 240ms for each channel. When “3" (unused) is set for a channel, this channel would not have A/D conversion, therefore, the total time for conversion decreases. In the above example, the conversion time is as follows:
 ms (conversion time per channel) × 2channels (number of channels used) = 480ms (total conversion time)
--* **Buffer Memory BFMs #1 to #4: Number of temperature readings to be averaged**

  When the value of averaged temperature is assigned to BFMs #1 to #4, the averaged data is stored in BFMs #5 to #8 (°C) and #13 to #16 (°F). Only the range 1 to 256 is valid for the number of averaged temperature. If a value out of this range, the default value is 8.

++1. Set the power-down retention register to a value of 100 (e.g., BFM#52 is set to 100).
++1. Set the power-down retention flag BFM#42 to 1 (data is saved at this point, and BFM#42 will automatically reset to zero upon completion).
++1. Change the data of the power-down retention register to 1000 (e.g., BFM#52 is set to 1000).
++1. Power off and then power on again. At this point, check the value of the power-down retention register, which should be 100 (e.g., BFM#52 shows a value of 100)."
