5.4 Thermocouple RJC setting
When using a thermocouple to measure temperature, select the reference junction between
the internal temperature sensor of the instrument and an external junction (such as Zero-Con).
1. Move the cursor (reversed indication) with
[▲][▼]
keys on the “Program” screen and
press
[ENT]
key, or press
[3]
of ten keys to
go to “RJC”.
(RJC is an abbreviation of Reference
Junction Compensation.)
2. Move the cursor with
[▲][▼]
keys to the
setting of the channel you want to set, and
press [
ENT]
key. With
[F3]
key, you can
go to “Group setting”.
3. Move the cursor to either “Internal
(junction)” or “External (junction)” with
[
◄][►]
keys, and press
[ENT]
key.
✍
The TC-32K has a built-in temperature sensor inside. This temperature sensor works
as a reference junction in thermocouple measurement when linearizing the output of the
thermocouple. The accuracy is equivalent to Class C measurement sy stem in JIS Z
8704.
To measure more accurately with a thermocoupe, select [External (junction)] and settle
a reference junction outside. The accuracty in this case is equivalent to Class B in JIS
Z 8704.
