We are going to test a 10 Watt LED Bulb using PT-AC (Production Tester- AC) LED Bulb Specification: –          Voltage: – 220V to 240V          Current: – 55 mAmp   (0.055 Amp)          Frequency: – 50/60 Hz          Power Factor: – >0.9          Wattage: – 10W
Set Tolerance in PT-AC: –          Current: – 0 Amp to 2 Amp          Power factor: – 0 to 1         Wattage: – 7W to 12W

         

Above specification is set in PT-AC meter in two ways- By PT-AC software OR Manually.

1.  Set testing tolerance in the PT-AC Software with name 10 Watt bulb on index 01

       

2. Set testing tolerance in the PT-AC meter Manually

   This video contain hole process of Set testing tolerance in the PT-AC meter and testing of loads.

Readings of PT-AC for the testing of 10 watt LED Bulb

PT-AC device shows Input Voltage on first screen from left side is 245.1 Volt

Comparision of LED Bulb specification and set tolerance in the PT-AC device

Parameters	bulb Specification	Set tolerance	PT-AC Values	Status
Current	0.055 Amp	0 Amp – 2 Amp	0.036 Amp	Pass
Power Factor	>0.9	0 – 1	0.9667	Pass
Wattage	10 W	7 W – 12 W	8.740 W	Pass

From the above result, All the parameters PASS according to set telerance. So this LED Bulb is OK.
