0.05 Class High-Precision 3-Phase Smart Meter Test Bench
Description
• Parallel RS232 Communication Port – simultaneous multi-meter
testing of smart meters
• Rack-Mounted Terminal Calibration – one-click bench verification
for test stations
• Reference Standard Meter Accuracy Testing – traceable precision
checks
• Pre-Warming Cycle – automated stabilization before measurement
• IEC Accuracy Test Suite – base error, starting current, creeping,
repeatability, dial test
• Influence Quantity Tests – voltage, frequency, reverse phase
sequence, voltage unbalance
• Harmonics & Sub-Harmonics – immunity to odd harmonics and
sub-harmonics per IEC standards
