Page 33: Handling Precautions
Do not use the sample includes those. Use under proper temperature range Operational temperature range of DP23C/33C/is room temperature +5 to 240℃. Operational temperature range of DP43C/63C is room temperature +5 to 200℃. Never set the temperature out of that. - Page 34 Handling Precautions Setting of sample Since the withstand load of the attached shelf plate is about 15kg per one plate, do not set heavier sample than 15kg. When setting several sample, set them as dispersed as possible. Too much sample setting could cause the improper control of the temperature. For keeping the proper temperature, keep more than 30% space against whole size of the shelf plate, and set the sample.
