Portable Type instruments are Electrodynamometer type instruments. They can be used in Single Phase, Three Phase Three wire and Three Phase Four wire systems, and are designed to be used in horizontal positions.

Electrodynamometer Type Meters
Rated Accuracy : ± 1.0% of full scale value as per ISS 1248/84 between 10% to 100% of the scale for Single phase UPF Wattmeters
: ± 1.5% of full scale value as per ISS 1248/84 for Three Phase Wattmeters
: ± 1.5% of full scale value as per ISS 1248/84 for 0.2 P.F. (LPF) Single Phase Wattmeter
: ± 3° (Electrical) as per ISS 1248 for Power Factor Meters
Note : All Wattmeters are calibrated at cos f = 1 and Varmeters at sin f = 1
: All Low Power Factor Watt meters are calibrated at cos f = 0.2 lag
: Other voltage and current ranges can be supplied on request, subject to technical feasibility
