4.3 apply the above soldering process for 1 or 2 times.

 

5. matters needing attention

5.1 high temperature high humidity or corrosive gases are prohibited in storage.

5.2 keep the principle of “first come, first use”.

5.3 the best way is to use the potentiometer as a four-terminal element for adjusting voltage of voltage divider. for wiring, you’d better choose terminal “1”for grounding and r1 (the load resistance of

   the potentiometer) should be not smaller than ten times as rt (see figure 2a).

  except for special design requirement, the potentiometer shouldn’t be used as a two-terminal rheostat. the contact resistance between the resistor and the contact piece will hinder the passing of big electric current, at the sane time, the current at the moving contact may be too big since only par of the effective travel is in function and lead to local over loading then failure of the unit.(see figure 2b).

5.4 when the potentiometer is used as current regulator in dc circuit, dc current will pass the sliding arm thus resistance value will rise abnormally because of anodic oxidation. in this case, in this case, it is recommended to connect the leading-out terminal of the resistor to the cathode and that of the sliding arm to anode.(see figure3c)
