High performance power analyser The HA1600 is a high speed, high accuracy AC power analyser for single phase supplies of up to 16 Amps rms. The supply to be measured is connected via a dedicated input cable independently of the supply to the instrument. The output to the load is via a front panel mounted 'standard' mains connector. A wide range of power connectors is available including most European national types. The HA1600 can measure Watts, VA, Volts rms, Volts peak, Amps rms, Amps peak, Crest factors, THD, Power factor, Frequency and Inrush current. The large display can show multiple parameters simultaneously along with graphical representations of voltage and current waveforms. Dual 16 bit Analog to Digital converters continuously sample both voltage and current and give a wide dynamic range. A fast Digital Signal Processor gives the performance needed for continuous real-time analysis of the data. Advanced algorithms yield accurate results, using extended precision or floating point arithmetic wherever necessary. Compliance-quality harmonics analyser The HA1600 has been designed to make harmonics measurements both quick and simple. It measures harmonics from the 1st to the 40th and updates the display in real time. It is suitable for pre-compliance measurements using a normal mains supply and is capable of full compliance measurements to EN61000-3-2 in conjunction with a suitable power source (such as the AC1000). Capabilities include continuous monitoring of the supply voltage, continuous comparison to harmonic limits and timed test sequences with analysis of fluctuating harmonics. Compliance-quality flicker meter The HA1600 has the capability to operate as a compliance quality voltage variation and flicker meter in conformance with EN61000-3-3 and EN61000-4-15. Flicker severity can be measured in terms of Pst and Plt while simultaneously performing full analysis of voltage variations, including the calculation of the maximum value dmax, the difference between steady states dc and the change characteristic d(t). For pre-compliance testing, a current measurement method can be used, rather than voltage measurement, to eliminate the need for a clean power generator and a reference impedance. A full range of interfaces A parallel printer interface is included, for record keeping and archiving, and also a high speed RS-232 interface is provided for use with either a printer or remote control software running on a PC. The HA1600A also has a USB port for use with the HA-PC Link Plus software. The internal software of the instrument is stored in flash memory and can be updated through the serial port as the requirements of the measurement standards evolve. HA1600 and HA1600A The two versions of the instrument are in different cases, with slightly different front panel layouts. The HA1600A has a USB port. In all other respects the operation and performance of the two types is identical. Both use the same firmware, and this manual applies to either type if fitted with firmware version 2.80 or late
