*1 The Q68TD-G-H01 needs to be powered for 30 minutes warm-up in order to satisfy with the accuracy. *2 Calculate the accuracy in the following method. (Accuracy) = (conversion accuracy) + (temperature characteristic) (operating ambient temperature variation) + (cold junction temperature compensation accuracy) An operating ambient temperature variation indicates a deviation of the operating ambient temperature from the range.
Page 12
*2 The accuracies only in the temperature ranges of Class 1 to 3 (shaded areas) in JIS C1602-1995 apply. Also, the Q68TD-G-H01 needs to be powered for 30 minutes warm-up in order to satisfy with the accuracy. *3 Temperature measurement can be executed, but accuracy is not guaranteed.
3. IMPLEMENTATION AND INSTALLATION 3.1 Handling Precautions (1) Do not drop or give a strong impact to the case. (2) Do not remove the printed-circuit board of the module from the case. Doing so may cause a failure. (3) Prevent foreign matter such as dust or wire chips from entering the module.

Q68TD-G-H01. (1) Use separate cables for the AC control circuit and the external input signals of the Q68TD-G-H01 to avoid the influence of the AC side surges and inductions. (2) Always place the thermocouple at least 100mm away from the main circuit cables and AC control circuit lines.
*4 When connecting the RTD, always connect the terminals between RTD- and RTD G. Figure 5.1 Wiring procedure POINT The Q68TD-G-H01 needs to be powered for 30 minutes warm-up in order to satisfy with the accuracy. Moreover, the Q68TD-G-H01 needs to be powered for 30 minutes warm-up when the offset/gain setting is performed and after the online module replacement is performed.
