3.8.2.1. General Procedures
Step 1) Connect the thermometer leads or the resistor to be measured on the
four terminals labeled Rx on the front panel, where C
1
P
1
identifies
one current potential pair and C
2
P
2
the other pair.
Step 2) Select a reference resistor and connect it to the four terminals labeled
Rs, also on the front panel. Normally a value is chosen that will
make the expected ratio lie between 1:1 and 13.4:1 (Rx:Rs). This
ensures the best available precision.
Step 3) From the <Main Menu> on the 6675A, select the <Setup Menu>
and make sure the softkey on the extreme right indicates <Resistors>
(and not <Probes> ).
and either:
Select a stored measurement configuration:
<Main> <Setup> <load> <select> ;
Use arrow keys to select a stored setup ;
<Ok> key to select setup ;
Then use <PREVIOUS> key to get back to the <Main Menu> so that the
<Measure Menu> can be selected
or:
Create a new measurement configuration:
<Main> <Setup> <Edit> <mode>
<4-terminal> <Edit>
