*1 It is the conversion time of the measurement value. Communication time is not included.
*2 It is the measured value under the condition of wind speed of 0-0.5m/s in the thermostatic bath.
*3 The cold junction tolerance is within 4.6 ° C when the product is installed in the orientation other
than vertical installation (Installation angle 0 °).
Installation orientation requires software command to change the settings. (Default: vertical
installation)
