Note
The Product can show some control sensitivity to moderate or severe electromagnetic
fields or conducted interference of certain frequencies. In the presence of radiated EM
disturbances, with frequencies of 250 MHz to 400 MHz and with amplitude >1 V/m to a
maximum of 3 V/m, add 0.0025 °C to the stability specification. Stability is not guaranteed
if amplitude is >3 V/m. When subject to conducted disturbances of 8 MHz to 80 MHz, and
amplitude >3 V, add 0.005 °C to the stability specification.
