After 8,000 hours with the others. In the case of the C.A 1821 and the C.A 1822, connecting the instrument to a PC via a micro USB cord causes an internal tem- perature rise in the instrument that may lead to a temperature measurement error of the order of 1.5°C. -
Page 19: Electrical Characteristics For The C.a 1823
This temperature rise does not occur when the instrument is connected to a wall outlet or when it is powered by batteries. Do not connect the C.A 1821 or the C.A 1822 to a PC to make measurements. Use this connection only to program the instrument or to transfer records. -
