PMT40820 Series Meter Calibration Console
The PMT40820 design represents a `next generation' single phase, automatic multi-position test system that effectively
extends the level of automation and functionality in comparison to existing products presently offered in the market.
As such, the system offers significant benefits with respect to productivity and efficiency.
Complete system automation has eliminated the typical practice of connecting leads and plugs to configure the voltage and current
circuits for a given meter type. The operator simply identifies the meter type and the system is ready to perform testing of
standard or user-defined test sequences. This capability provides several benefits encompassing enhanced productivity, reduced
learning curve, meter protection, equipment protection and operator safety.
The system architecture allows consoles to be configured with 10 positions supporting direct S-base testing. Bottom-connected
meters can be tested with adapter sockets or hard-wired to the provided current and voltage terminals. A single-phase, phantom
load source, powered from solid-state amplifiers provide Measurement Canada EL-ENG-12-01 compliant voltage and current waveforms.
An integral host computer provides a direct, intuitive and `user-friendly' operator interface based upon the Microsoft Windows 11
operating system. The hosting computer provides automatic execution of pre-programmed test sequences, storage of meter records,
printing of test certificates and reports, statistical analysis and connection to a local area network as required.
Additional features of the system include a precision Dual Reference Standard, state-of-the-art optical pickup, local Station
Error displays, Station KYZ pulse inputs and dual Pulse Generator.
Of concern to Canadian utilities and manufacturers, the PMT40820 has been designed to meet or exceed the present Measurement Canada
EL-ENG-12-01 specification for Electricity Measuring Apparatus.
