*1 The resolution is determined by the setting of the “sampling period” in the parameter.
When the resolution is 1°C: Set to “high speed.”
When the resolution is 0.1°C: Set to “low speed.”
*2 The overall accuracy is the specication for when noise described in “Electrical service conditions” is not applied.
If noise is applied, the overall accuracy may exceed the above specication.
*3 Immediately after the main unit is powered on, the A/D conversion value becomes “-32767” until the analog unit collects
analog values from external devices and starts A/D conversion (approx. 10 seconds.)
*4 If connection between the analog unit and a temperature sensor is broken, the temperature conversion value becomes
“28767.”
