Overview
The HA1600A is a fast, easy to use mains and harmonics
analyser with a large and high resolution graphical display, capable of
continuous real-time analysis.
The HA1600A is intended primarily as a dedicated harmonics and flicker analyser
for compliance quality measurements, but it can also be used as a general
purpose mains analyser.
The unit is available with range of power connectors to suit different national
standards.
A printer interface is included for record keeping and archiving, along with
both RS-232 and USB interfaces for PC connectivity.
High performance power analyser
The HA1600A is a high speed, high accuracy ac power analyser
for single phase loads of up to 16 amps RMS.
Dual power cables allow the supply to the load to be independent 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 national types.
The HA1600A 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 as well as
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
All electrical equipment sold within the EEC
must comply with legislation relating to the harmonics content
of the current waveform.
The HA1600A has been designed to make these 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 AC1000A.
Support is provided for both the 1995 and 2000 editions of
EN61000-3-2. Capabilities include continuous monitoring of the
supply voltage, continuous automatic calculation of harmonic
limits, and timed test sequences with analysis of fluctuating
harmonics.
Compliance-quality flicker meter
The HA1600A can operate as a compliance
quality flicker and fluctuations meter in conformance with
EN61000-3-3 and EN61000-4-15.
A current measurement method can be used, as an alternative to
voltage measurement, thus eliminating the need for a reference
impedance.
Flicker severity is measured in terms of Pst and Plt using
analysis periods as defined within the standard.
Simultaneously full analysis of voltage variations is performed,
including the calculation of the maximum value dmax, the
difference between steady states dc, and the change
characteristic d(t).

HA-PC LINK PLUS SOFTWARE
HA-PC LINK PLUS is PC (Windows) software supplied with the HA1600A. It can
communicate with the instrument through either an RS232 or a USB connection.
It is intended to assist users in taking routine compliance measurements and
archiving the results.
The PC is used for configuration, display and data archiving only; all real time
data handling and measurement processing continues to be performed by the
Digital Signal Processor in the instrument. The performance of the PC does not
affect the accuracy of the measurement results, and so there is no need for the
either the PC or its software to be covered by a calibration certificate.
