1. Overview
1.1 Introduction
This manual covers the 66203 and 66204 Digital Power Meters that have 3 and 4 channels
respectively to test multiple UUTs at the same time reducing the testing time and improving
the productivity. The Digital Power Meter can also test the products with 3-phase power
system through the test parameters of voltage, current, power and power factor. It can test
the input and out power of a UUT at the same time and compute the efficiency easily via the
function of efficiency calculation.
The 66203 and 66204 Digital Power Meters have two internal shunts (low shunt and high
shunt) which are configured within 5mA~20A current range. They can be applied to low
and high power measurements comprehensively especially the highly accurate capability
equipped in testing the standby power for energy star. This Digital Power Meter also has
external sampling function to expand the current measurement range if the test current is
over the range of maximum 20Arms. Moreover, the Digital Power Meter is able to analyze
the voltage and current measurement for power quality test. Working with the exclusive
soft panel, the Digital Power Meter is able to create a complete test report and comply with
the power quality test standard.
The limit function utilized in production test is able to perform GO/NG judgment based on
the upper/lower limits for voltage, current and power total 16 parameters. In addition, the
measurement functions such as energy, inrush current and crest factor, etc. are also
available for use.
1.2 Initial Inspection
Before shipment, this Model 66203/66204 was inspected and found to be free of mechanical
and electrical defects. As soon as the instrument is unpacked, user should inspect for any
damage that may have occurred in transit. Save all packing materials in case the
instrument has to be returned. If damage is found, please file a claim with the carrier
immediately. Do not return the product to Chroma without prior approval.
