Maintenance

 

There  are  no  user  serviceable  part  inside  PSD4032A.  Your  PSD4032A  Power 

Supply is thoughtfully engineered for ease of use, accuracy and reliability. The 

instrument is carefully tested and calibrated using standards traceable to National 

Laboratories. 

Take care of your instrument by cleaning the exterior of the instrument regularly 

with a dusting brush. Dirt which is difficult to remove on the casing & plastic parts, 

can  be  removed  with  a  moist  cloth  (  99%  water,  1%  mild  detergent)  spirit  or 

washing benzene(petroleum ether) can be used to remove greasy dirt. The display 

may  be  cleaned  with  water  or  washing  benzene  (but  not  with  spirit-alcohol 

solvents),  it  must  then  be  wiped  with  a  dry  clean  lint-free  cloth.  Under  no 

circumstances  the  cleaning  fluid  should  get  into  the  instrument.  The  use  of 

cleaning agents can attack the plastic & paint surfaces.

Power Line Fuse Replacement

The  power  line  fuse  is  located  on  rear  panel  on  lower  right  side.  In  case,  the 

instrument does not show any sign of working, no LED is lit or there is no display, 

immediately switch OFF the mains power switch of the instrument and unplug the 

mains cord from the mains socket.

With the help of small flat blade screwdriver remove the fuse cap of the fuse holder, 

located just below the socket. There is one spare fuse kept in the fuse cap, replace 

it for the defective one. Turn the cap so that it locks in place . The rating of the fuse is 

2 A , 250V , sloblo , 5x20 mm glass fuse. Do not use a fuse with a higher value other 

wise it may damage the instrument in case, the mains voltage goes much higher 

than the rating of the mains fluctuation of + 10% .
