CONNECTION FOR TC MEASUREMENTS USING EXTERNAL
RJ
When a TC with external stable reference junction box is used,
connect the copper cable of the stable reference junction box to the
instrument and set the external reference junction compensation
value as shown below.
3.2 TC MEASUREMENTS
NOTES
: 1) to enable/disable the open input test, see the para-
graph "2.3 INSTRUMENT CONFIGURATION".
2) The instrument will operate in accordance to the selected
temperature standard (IPTS-68 or ITS-90) (see para-
graph "2.3 INSTRUMENT CONFIGURATION").
CONNECTION FOR TC MEASUREMENTS USING INTERNAL RJ
For all TC measurements it is suggested to connect the cables
directly to the instrument connectors without any additional plug.
If plugs are required, it is necessary to use gold plated banana
plugs in order to avoid not desired junction effects between cables
and plug material.
