Functions: TW-13A

Ø         Basic parameters measurement

Basic parameters measurement could display voltage effective value, current effective value, frequency and other basic parameters and measurement waveform charts of voltage and current, and could display average value when measuring DC measurement source.

Ø         Single-phase power measurement

Single-phase power measurement could display apparent power, active power, reactive power, power factor. It could display DC power when measuring DC measurement source.

Ø         Harmonic measurement of electric grid

Harmonic measurement of electric grid is divided into harmonic measurements of voltage harmonic and current harmonic, which could mainly display the conditions of harmonic of 1-25 times, and it includes harmonic(or fundamental) time、harmonic real effective value、harmonic ratio (HR)、total harmonic distortion (THD) and histograms of all harmonics.

Ø         Oscillograph

Oscillograph could display measurement wave forms of voltage and current， and it has three working states: running, keeping(that is manual catching), touching(that is automatic touching).

Ø         Start-up measurement

Startup measurement is used for measuring the shock of electric grid by startup and stopping of large-scale equipment (mainly current).

Ø         Measurement record

It could perform long-term monitoring record for voltage, current, frequency, power factor, voltage harmonic, current harmonic and other parameters, which could obtain max value, average value, minimum value of above parameters within record time and the change trend curves of all parameters within record time.

Ø         Data analysis

This function allows the user to upload the saving data to PC for all kinds of analyses.

Ø         System updating

This function allows the user to use computer to update the program of instrument.
