► Frequently Asked Questions about Janitza
|
What is the difference between Class A and Class S power quality analysers?
Class A is the highest measurement class per IEC 62586 and EN 61000-4-30 – required for standards-compliant documentation, arbitration procedures and regulatory requirements. Class S (Survey) is suitable for general monitoring tasks where the highest accuracy is not mandatory.
|
|
What software is required for Janitza devices?
Janitza offers GridVis® software in various versions: GridVis Desktop for single-workstation evaluation and GridVis Enterprise for network-based monitoring of many measurement points. The software enables standards-compliant reports to EN 50160 and IEEE 519 as well as alarming and trend analysis.
