Safety Voltages
Connect only voltages that are within the following limits.

Measurement Category I
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.

To meet these shock and vibration specifications, you must panel mount the system.
Calibration
Calibration interval | 1 year |
1 The DC + AC voltage must be below the overvoltage protection of the NI-9230.
2 Refer to the software help for information on reading the IEPE fault detection status.
3 Range equals 31.5 V
4 DC coupled
5 Uncalibrated accuracy refers to the accuracy achieved when acquiring data in raw or unscaled modes and in which calibration constants that are stored in the module are not applied to the data.
6 Rejection of analog prefilter at oversample rate.
