NOTE
Measurement range and measurement input upper and lower limits
Note that the measurement input upper and lower limits change according to
the measurement range.
When the following upper and lower temperature limits are exceeded, the
waveform is saturated.

If the input terminals on the 8954 VOLTAGE/TEMP UNIT come into direct
contact with strong winds, the thermal balance of the input module may be
upset, causing an error to occur. When measuring in this type of location,
change the location of the module so that it is not in direct contact with the
wind.
When the peripheral temperature changes suddenly, the thermal balance may be
upset, causing an error to occur. In this case, leave the instrument for
approximately an hour and start measuring once the temperature has stabilized.
