VII. Usage and Maintenance Instructions

(I) Installation and Power On

Before installation, turn off the power, insert the module into a single slot of the PXI chassis, tighten the panel screws for fixation.

After power-on, preheat for 30 minutes to ensure measurement accuracy (reducing temperature drift influence).

Confirm in NI MAX that the device identification is normal and there are no errors, complete driver installation and self-check.

(II) Wiring and Operation

Caution for high voltage / large current: When measuring ≥100 V or ≥100 mA, use a safety banana plug to avoid electric shock.

4-wire resistance wiring: I+ / I- (current wires) and V+ / V- (voltage wires) are connected separately to eliminate lead resistance error.

Range selection: Prefer automatic range; when using manual range, start from the largest range to avoid over-range damage.

Trigger settings: When multi-module is synchronous, configure through PFI trigger line to ensure consistent measurement timing by NI.

(III) Maintenance and Calibration

Regular calibration: It is recommended to calibrate once a year or calibrate when accuracy drifts. Use NIST traceable standard source.

Cleaning and maintenance: Use a soft-bristled brush to remove dust, avoid contact with liquids; Keep the interface dry and cover it with a dust cap when not in use for a long time.

Environmental control: The working temperature should be controlled within 0 ℃ to 55 ℃. Avoid high temperature and high humidity to extend the module's lifespan.

Avoid overloading: Do not exceed the range (such as input of 300 V range > 300 V) to prevent internal circuit damage.
