*1 Data is not backed up when the power is turned off. The available data buffer memory per NR-X100W and NR-XR01 group is limited to 25M.
*2 Use only products recommended by KEYENCE (CA-SD4G: 4 GB, CA-SD16G: 16 GB). Using a product not recommended by KEYENCE may result in data not being saved to the SD card during continuous acquisition.
*3 Wired LAN and wireless LAN cannot be used at the same time. When acquiring data from a PC (using WAVE LOGGER X software), use a wired local connection only between the NR-X100W and the PC. Using an onsite local network connection or wireless LAN connection may cause acquisition to stop due to a decrease in transfer speeds caused by network load or wireless LAN communication conditions. The main unit’s automatic saving function allows data to be saved to an SD card in the main unit even if acquisition by PC stops.
*4 Use is permitted only if the total power consumption of all connected measurement units is 20 W or less.
*5 Use is permitted only if the total power consumption of all measurement units, remote units, and environment-resistant measurement units used in the system is 50 W or less when remote units are not connected to an AC adapter.
*6 Acquisition from a PC may not be possible in some PC environments. [Tested conditions] OS: Windows 10 Pro (64 bit), CPU: 3.70 GHz, RAM: 16.0 GB, USB connections: One NR-X100W (no other USB devices), Ethernet connection: One-to-one connection between NR-X100W and PC; Using normal mode and saving in the standard format with a pre-installed OS and running only WAVE LOGGER X. Windows is a registered trademark or a trademark of Microsoft Corporation in the United States and/or other countries.
*7 Each master data collection unit group and remote unit group is limited to 100 kHz for all acquisition channels. When using 5 or more remote units, each remote unit group can have up to 50 kHz per acquisition channel.
*8 The sampling cycle and sampling timing vary depending on the connected measurement unit. When using the NR‑CA04 in combination with other unit types, a sampling delay may occur between the NR-CA04 and the other units with some setting configurations.
