System Requirements
OS and Third Party Runtime
• Windows7 (x86/x64) is recommended. Vista (x86/x64) and XP-SP2 (x86) are also supported.
• Microsoft Visual C++ 2008 Run-Time Engine
• .NET Framework 2.0 or newer
• NI-VISA 15.0 or newer.
Hardware Requirements
• A digital multimeter that has voltmeter function with 5.5 digits precision or higher.
• A shunt resistance that can flow the maximum DC current of your RMX power supply's
current capacity.
• Load wires that can flow the maximum DC current.
Environment
Perform calibration in the following environment:
• Temperature: 23 °C ± 5 °C
• Humidity: 80% rh or less
Warm up the RMX programmable power supply for at least 30 minutes before calibration.
Also, ensure to warm up the DVM and shunt resistor for the duration listed in their documentation.
Cleaning
If the panel needs cleaning, gently wipe it using a soft cloth with water-diluted neutral detergent.
Do not use volatile chemicals such as benzene or thinner.
