:
Reference junction compensation is performed internally
by the 8937.(Measurement accuracy is the sum of the
accuracy of temperature measurement plus reference
junction compensation accuracy.)
:
Reference junction compensation is not performed by
the 8937. Select this option when using an external
reference junction compensation unit. (Measurement
accuracy refers only to the accuracy of temperature
measurement.

(3) Set the reference junction compensation.
1. Move the flashing cursor to the point shown in the
figure on the left.
2. Use the function keys to make a setting.

Measurement range and upper and lower limits of measurement input
Note that the upper and lower limits of measurement input vary according to
measurement range. Waveform saturation will result if the limits indicated in
the table below are exceeded.
