18 e type l digital r potentiometer t test method

1. Required tools, instruments and equipment A small flat-blade screwdriver, a thermal melt gun, a Tektronix oscilloscope, a DC regulated power supply, and an electric rotary digital display indexing table.

2. Measurement

1. First fix the potentiometer to be measured on the electric rotary indexing table, and fix it with hot melt glue to prevent errors caused

by tooling gaps when adjusting the angle;

2. Connect the power lines V and G of the potentiometer to the DC regulated power supply, connect the output signal lines O and G to the first probe of the oscilloscope channel, and turn on the power switch of the oscilloscope to preheat in advance;

3. Turn the output adjustment knob of the DC stabilized power supply to the minimum, then turn on the power supply, and adjust the output voltage to 5VDC;

4. Observe the oscilloscope and record the PWM frequency;

5. Rotate the indexing table to make the potentiometer rotate clockwise, and observe whether the signal duty ratio gradually increases;

6. Rotate the indexing table to find the position with a duty cycle of 5%, and the angle display of the indexing table returns to zero;

7. One test point at 10°, record the angle and duty cycle data;

8. Calculate the angle deviation after the test is completed. If the angle deviation is less than 0.7°, the potentiometer is judged to be
