7. Automatic compensation of cold junctions
When calibrating meter with temperature cold
junction compensation directly, press
〔
RJ-ON
〕
key to
start the automatic compensation function of cold
junctions of this meter, and it will output the necessary
temperature thermoelectric force, and display ‘RJ-ON’.
(See detailed section for the accuracy of cold junction
compensation), and :
Output thermoelectric force = the corresponding
thermoelectric force of set temperature
–
the
corresponding thermoelectric force of room temperature
*
The Users need to wait for 2 seconds when
starting the interior cold junction compensation of
the meter and the meter will make automatic
compensation every 10 seconds
*
When the operation ambient temperature change,
the Users need to wait until the interior
compensation sensor stabilizes (about 10 minutes)
and then use
*
if the Users do not use the automatic
compensation function of this meter, press the
〔
RJ-ON
〕
key and the symbol
‘
RJ-ON
’
will not
display any more
8. Press
