1. What is the difference between UPF and LPF portable wattmeters?
UPF (Unity Power Factor) meters are used for resistive loads ($\cos\phi = 1.0$), while LPF (Low Power Factor) meters measure inductive/capacitive loads ($\cos\phi = 0.2$).
2. Does this wattmeter measure both AC and DC power?
Electrodynamometer type wattmeters accurately measure true active power in both AC and DC electrical circuits.
3. Are patch cords included with the portable carrying case?
Yes, standard 4mm insulated laboratory connecting leads are supplied with the meter.
4. How is the scale factor calculated for multi-range models?
A multiplication factor chart is printed on the dial face for easy calculation based on selected voltage and current terminals.
5. Do you ship these meters to international university labs in USA, UK, and UAE?
Yes, we export globally alongside Heat Apparatus and Magnets.
6. Do you offer bulk institutional tender discounts?
Yes, we provide wholesale pricing and tender support documentation for institutional university orders worldwide.
7. What warranty coverage comes with the product?
Every Portable Analog Wattmeter comes with a 1-year replacement warranty against manufacturing defects.
