VII. Installation and Maintenance Instructions

Installation and Power On Disconnect the power supply and insert the PXI single slot, with the chassis grounded; after powering on, perform self-checks by NI-DAQmx. It is recommended to preheat for 10 minutes.

Operating temperature: 0 - 55℃. Ensure the air duct is unobstructed and avoid blocking the fan.

Connections and Operations

Use shielded twisted-pair cables for analog input, with differential connection to suppress interference; the input voltage should not exceed ±10 V.

Avoid frequent plugging and unplugging of the 68-pin interface; it is recommended to use a wiring box for transition; perform anti-static operations.

When synchronizing multiple modules, share the PXI 10 MHz reference clock and trigger bus.

Daily Maintenance and Calibration

It is recommended to conduct a traceable calibration once a year to compensate for gain/offset drift; built-in self-calibration corrects temperature drift.

Keep the interface clean and cover it with a dust cover when not in use for a long time; avoid strong vibrations and humid environments.
