Table 22. Channel to Channel
Channel-to-channel None
Table 23. Channel to Earth Ground
Continuous 250 V RMS, Measurement Category II
Withstand 2,300 V RMS, verified by a 5 s dielectric withstand test

Measurement Category II

Caution Do not connect the product to signals or use for measurements within Measurement Categories III or IV.
Attention Ne pas connecter le produit à des signaux dans les catégories de mesure III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.

Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

Calibration

You can obtain the calibration certificate and information about calibration services for the NI-9263 at ni.com/calibration.
Recommended calibration interval 1 year

1 When the module powers on, a glitch occurs for 20 μs peaking at -1.5 V.

2 The power-down voltage peaks at 1.8 V before exponentially discharging to 0 V in 100 μs. To reduce the peak voltage, add a 10 kΩ load.

3 Range equals ±10.7 V

4 Uncalibrated accuracy refers to the accuracy achieved when acquiring in raw or unscaled modes where the calibration constants stored in the module are not applied to the data.
