Kahan Use Hota Hai (Use Cases)
- 🏠 Ghar ki AC/DC wiring check karna — Bina wire kaat ke live current safely measure karein
- 🏭 Industrial panel & 3-phase motor testing — High current loads aur distribution boards ki monitoring
- ⚡ UPS, inverter & solar system troubleshooting — DC current aur AC output dono measure hota hai
- 🎓 BSEE/BSCS FYP projects — Load analysis, power factor measurement, aur circuit verification
- 🔧 HVAC, motor & compressor testing — Starting current aur running current dono check karein
Kaise Use Karein (How to Use)
AC Current Measurement:
1. Dial → 400A~ (ya 40A~ for lower range)
2. Trigger dabao → jaw open karo → single conductor ke around close karo
3. LCD pe auto-range reading dekhen
DC Current Measurement:
1. Dial → 400A= position
2. REL/ZERO button dabao → zero set karo
3. Jaw conductor ke around lagao → reading lo
NCV (Non-Contact Voltage):
1. Dial → NCV
2. Meter tip live wire ke paas le jao
3. Beep + LED flash = voltage present hai
AC/DC Voltage (Test Leads):
1. Red lead → V terminal, Black → COM
2. Dial → V~ (AC) ya V= (DC)
3. Probes circuit ke across lagao
Capacitance:
1. Dial → F (capacitance)
2. Capacitor leads → V aur COM terminals
3. Reading auto-range mein aayegi
FAQ
Q: Kya UT203+ DC current bhi measure kar sakta hai?
A: Yes! Unlike most basic clamp meters, the UT203+ measures both AC and DC current up to 400A via the clamp jaw. Use REL/ZERO to null out any offset before measuring DC.
Q: Kya yeh True RMS hai? Inverter ke saath kaam karega?
A: Yes — True RMS gives accurate readings on non-sinusoidal waveforms like inverter output, VFDs, and switching power supplies. Average-responding meters give wrong readings on these.
Q: Battery included hai?
A: No — 2 × AAA (R03 1.5V) batteries required, NOT included. Alag se leni hongi.
Q: Kya yeh 3-phase industrial wiring ke liye safe hai?
A: Yes — CAT III 300V / CAT II 600V rated. Most residential and light industrial applications ke liye suitable hai Pakistan mein.
