(*1) The included lithium battery (LS14250) is not sold in stores. Please purchase the optional battery set (TR-11P2) for replacement. (*2) Only use the CR2 within temperature range of -20 to 60 °C, avoiding exposing the CR2 to excessive vibration such as transportation. (*3) Battery life depends upon the measuring environment, recording interval, and quality of the battery being used. When infrared communication function is enabled, battery life may be further shortened if the unit is used under the inverter type fluorescent lighting. (*4) This is the waterproof capacity of the data logger with the sensor connected.

(*1) The included lithium battery (LS14250) is not sold in stores. Please purchase the optional battery set (TR-11P2) for replacement. (*2) Only use the CR2 within temperature range of -20 to 60 °C, avoiding exposing the CR2 to excessive vibration such as transportation. (*3) Battery life varies depending upon the ambient temperature in which it is used, the recording interval, the frequency of communication, and the 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 the infrared communication function is enabled, battery life may be shortened further if the unit is used under the inverter type fluorescent lighting.
