|*5) If necessary, serial communication can be established by using our TR-77Ui communication protocol (contact your local dealer) to write a software program. In this case, it will be necessary to connect to your computer using our optional serial communication cable (TR-07C). Please contact the dealer where the product was purchased or the T&D Sales Department.

*1) When used at temperatures equal to or higher than 0°C, the Humidity Measuring Accuracy will be as shown here.
*2) When used at temperature / humidity equal to or lower than the following: 50°C/75%RH, 60°C/50%RH, 70°C/35%RH, 80°C/25%RH
*3) One data set consists of readings for all channels in that type of unit.
*4) Battery life varies depending upon the type of battery, the measuring environment, the frequency of communication, and the ambient temperature in which it is used.When infrared communication function is enabled, battery life may be shortened if the unit is used under the inverter type fluorescent lighting.
