Thermocouple
Definition
M3510A is built-in cold junction compensation that can improve the
accuracy of thermo measurements. If you are using this function, you
have to set an adapter type. For example, through the “TYPE” selections
you are available to use a specific adapter B, C, E, J, K, N, R, S or T for
temperature measurement.
Perhaps it’s not the solution you want according to your application. Pick
the next selection RJUNCTION’s REAL or RJUNCTION’s SIMULATED by
the procedure SHIFT > TEMP > CONFIG > RJUNCTION >
REAL/SIMULATED. This procedure is not for the settings, but the function
execution. Before executing, please go setting REAL or SIMULATED
peremeters by the procedure SHIFT > TEMP > CONFIG >
SIMULATED/REAL.
What’s the difference between the REAL and the SIMULATED? For the
REAL, it’s a cold junction compensator whose standard value is detected
from the present internal equipment, i.e. the value would be frequently
influenced and changed at different environments and climates, and it
can’t be adjusted. For the SIMULATED, the SIMULATED value is a
reference value. To use this function, you need to be aware that the
temperature value from a certain object is absolute meaningful and
accurate, for example 0
℃
(mixed ice and water). After you well selet the
type and matched the correct adaptor, the tested result from the mixed
ice and water is 2
℃
. At this circumstance, you know the real and tested
error is 2
℃
. So the next step is to adjust the default value from 25
℃
to
23
℃
. Then your following thermocouple measurements with the
simulated function would be accurate.
How to set up thermocouple
You can set up the thermocouple configuration either through the front
panel operation or through the remote interface operation.
