VII. Installation and Maintenance Instructions

Installation and Power On

Insert the single slot when power is off， chassis reliably grounded； After powering on, NI-DAQmx performs self-check and preheats for 15 minutes.

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

Connections and operations

Use shielded twisted-pair cables for analog inputs; differential connections are preferred in strong interference scenarios.

Input voltage should not exceed ±10 V; avoid frequent plugging and unplugging of the 68-pin interface; it is recommended to be connected to a wiring box.

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

Daily maintenance and calibration

It is recommended to conduct a traceable calibration once a year; built-in self-calibration compensates for temperature drift.

Keep the interface clean, prevent dust accumulation during long-term inactivity; keep away from strong vibrations and condensation.
