10 Watt LED Bulb Testing
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.
Setting Methods:
- Set testing tolerance in the PT-AC Software with name 10 Watt bulb on index 01
- Set testing tolerance in the PT-AC meter Manually
This video contains the whole process of setting 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
Comparison 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 |
Test Result
From the above result, All the parameters PASS according to set tolerance. So this LED Bulb is OK.
