NEXT-GENERATION SMART METER TESTING SOLUTIONS

Adv-Multi-Channel Communication Testing

OPTICAL PORT

Enables simultaneous communication with IEC62056 compliant meters via dedicated optical heads, ensuring precise data transmission and software reporting.

GPRS/ GSM

Seamlessly integrates with gateways, clouds, or servers to capture wireless responses, enabling direct data comparisons against optical readouts.

HES API

Facilitates end-to-end simultaneous testing, supporting advanced alerts generation and Over-The-Air (OTA) operations via test server APls.

Core Functional Validation

DATA & PROFILES

Thorough validation of object lists (e.g., Public Client, MR, US) and precise reads of instantaneous parameters including Voltage, Power Factor, and frequency. Automatically extracts critical billing profile parameters.

LOAD & DEVICE MANAGEMENT

Conducts remote connect/disconnect verification for prepaid meters by operating and validating load switches. Automatically extracts nameplate details and verifies or alters net metering modes.

Metrological Efficiency & Burden Measurement

IDLE MODE

Measures baseline power consumption when the primary communication module is completely inactive.

ACTIVE TRANSMISSION

Evaluates the electrical burden placed on the system during active data bursts per communication module.

IHD MODULE ACTIVE

Calculates the specific load requirements when the meter is actively servicing an auxiliary In-Home Display (IHD).

Tamber Simulation & Stress Resilience

ELECTRICAL TAMPERS

Simulates critical events like missing, reversed, or unbalanced voltage/current, verifying exact responses across both Optical and GPRS ports.
