10 Watt LED Bulb Testing
|
We are going to test a 10 Watt LED Bulb using PT-AC (Production Tester- AC)
LED Bulb Specification: –
|
|
Set Tolerance in PT-AC: –
|
|
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.
Connection diagram of AC Power Source and Testing 10 Watt Load with PT-AC meter
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.
