*1: When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be
measured at temperatures below -20°C.
*2: Compared to the value measured by the T&D standard sensor for calibration under our calibration light source.
*3: If you wish to use infrared communication to download recorded data, it is necessary to purchase the Data Collector TR-57DCi (sold separately).
*4: Customers wishing to write their own software, please contact your local distributor for the serial communications protocol specifications. (Note: Optional serial
communication cable TR-07C is also required.)
*5: Battery life varies depending upon multiple factors including ambient temperature, recording interval, frequency of communication, and battery performance. All
estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life. When infrared communication function is
enabled, battery life may be shortened if the unit is used under the inverter type fluorescent lighting.
The specifications listed above are subject to change without notice.
