1) Turn off power.
2) Remove the short bar ® - © .
3) Connect variable resistor
as shown Fig. 7.
Note:
R
must be 10 k ohms. Use a two-core shield cable and con-
t
nect the shield line to (5). For F^ select one which will be af-
fected little by temperature
noises.

Control by resistance (II)
It is possible to output voltage which is inversely proportional
to resistance. Overshoot does not occur when switching
resistance.
