Transients During Power-Up and Power-Down
Attention must be paid to the setup and operation of your NI PXI-4130. Transients may appear across the terminals (typically <1 V) during power-up, power-down, and when loading the device driver.
To minimize the risk of damage to sensitive devices, NI recommends that all power supplies and SMU connections are disconnected while performing any of the above operations.
In case of chassis power failure, transients may appear across the output terminals. Consider employing an uninterruptible power supply system to avoid damage to extremely sensitive devices.
