MTE PWS 2.3 Details

MTE PWS 2.3

Reference Standard

The PWS 2.3 PLUS Portable Working Standard is a three-phase portable electronic meter test unit, used for testing single and three-phase electricity meters on site. The PWS2.3 PLUS allows checking of all meter installation parameters and associated circuits. The PWS 2.3 PLUS, with integrated instrument transformer test functions, is available in accuracy classes 0.1 or 0.2. The unit can be used either with a direct connection in the range of 1 mA ... 12 A, or by using a set of 3 active 100A error compensated clamp-on CT’s (included in the standard accessories set) in the range 10 mA …100 A. It is therefore possible to easily and accurately measure both CT and direct connected meters. The unit can be powered either from the measuring circuit or from an auxiliary single-phase supply.

Advantages:

Precision test equipment for AC values in the 45 Hz to 66 Hz frequency range

Wide measuring range with auto ranging

Display of vector diagram for analysis of mains conditions and meter connections

Measurements of wave forms and harmonics with display

Easy detection of circuit connection faults

Data memory for test results and customer data

Small dimensions and light in weight

Serial interface for data transfer (RS 232)

Function:
