to change the numerical value of the
set digits. The value can do carry or number decrement
automatically. Hold the pressed key in one second and the
numerical value will keep varying.
7) Automatic Compensation for Reference-Junction Temperature:
During the direct calibration of an instrument with reference-
junction temperature compensation, it is common practice to
press the key

so that the calibrator can start the
function of automatic reference-junction compensation, thus
providing the required thermo-electromotive force for output
followed by displaying the symbol ‘RJ-ON’.(Refer to section 8
concerning the reference-junction compensation accuracy of
the calibrator.)


It takes two seconds for the calibrator to start its internal
reference junction compensation. After this, each
automatic compensation takes place at intervals of 10
seconds.

If there is a change in the operating ambient temperature,
do not start the operation until the built-in compensating
sensor had become stable (ca.10 minutes).
 If there is no need for the calibrator to use the function of
automatic reference-junction compensation, the symbol
‘RJ-ON’ will no longer appear in the display by pressing the
key
