Testing of variable resistor of 504 w
components required for testing of variable resistor or potentio meter are
1. variable resistor
2. digital multi meter with probes
3. bread board
4. connecting wires
5. screw driver
procedure :
step 1
connect the multimeter with probes positive and negative with signs given + , -
connect the multimeter with probes positive and negative with signs given + , -
step 2
connect the multi meter probes and connecting wires
connect the multi meter probes and connecting wires
step 3
place these connnecting wires in the bread board
step 4 Then place the variable resistor in series of the connecting wires and see the reading of themulti meter it will be .300 then place the tester or screw driver on the variable resistor screw and rotate anti clock wise until 000 units and then rotate clock wise until .500 units or it should be plus + or minus- 10 that of .500
place these connnecting wires in the bread board
step 4 Then place the variable resistor in series of the connecting wires and see the reading of themulti meter it will be .300 then place the tester or screw driver on the variable resistor screw and rotate anti clock wise until 000 units and then rotate clock wise until .500 units or it should be plus + or minus- 10 that of .500
note :
check the multi meter readings correctly it should be + or - 10 percent that of .500 units
