*Units using Input of mV have a maximum span of 1000mV, setting unit past this range can cause premature
saturation of analog output.
Making temperature measurements at the extreme upper limit of the thermocouple is di󰀩cult at
best. When you exceed the upper limit, if the transmitter clamps, you are basically blind. Moore
Industries allows you to congure the upper range of the transmitter slightly higher than the
thermocouple limit. It is simply a linear extrapolation. We do not attest to the accuracy of the
measurement above the thermocouple limit, however, having a measurement rather than being
blind may be benecial in some applications.
