Connector Types

The NI-9205 has more than one connector type: NI-9205 with spring terminal and NI-9205 with DSUB. Unless the connector type is specified, NI-9205 refers to all connector types.

The NI-9205 with spring terminal is available in two types: push-in spring terminal and spring terminal. The push-in type spring terminal connector is black and orange. The spring terminal connector is black. NI-9205 with spring terminal refers to both types unless the two types are specified. Differences between the two types of spring terminal connectors are noted by the connector color.

Analog Input Absolute Accuracy

The following values are based on calibrated scaling coefficients, which are stored in the onboard EEPROM.

Table 11. Absolute Accuracy
Range Accuracy at Full Scale[1]1 Absolute accuracy values at full scale on the analog input channels assume the device is operating within 70 °C of the last external calibration and are valid for averaging 100 samples immediately following self-calibration. Random Noise, [2]2 Differential mode.σ Sensitivity[3]3 Sensitivity is a function of noise and indicates the smallest voltage change that can be detected.
Within 2 Years of Calibration Within 10 Years of Calibration
±10 V 6,230 μV 7,280 μV 237 µV RMS 96.0 μV
±5 V 3,230 μV 3,750 μV 121 µV RMS 46.4 μV
±1 V 692 μV 800 μV 29 µV RMS 10.4 μV
±0.2 V 175 μV 195 μV 15 µV RMS 4.0 μV
Note NI recommends a calibration interval of 2 years and only provides calibration services referencing the 2-year specification limits. If you choose to calibrate less often, the 10-year column provides predicted performance over this extended interval. Choose an appropriate interval based on your application requirements. Longer calibration intervals are more likely to result in As-Found calibration failures when the device is sent back for calibration and compared against the 2-year specification limits.

Analog Input Accuracy Formulas

Absolute Accuracy = Reading * Gain Error + Range * Offset Error + Noise Uncertainty

where

  • Gain Error = Residual Gain Error + Gain Tempco * Temp Change from Last Internal Cal + Reference Tempco * Temp Change from Last External Cal
  • Offset Error = Residual Offset Error + Offset Tempco * Temp Change from Last Internal Cal + INL Error
  • Noise Uncertainty = (Random Noise * 3) / √100 for a coverage factor of 3 σ and averaging 100 points

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

  • Temp Change from Last External Cal = 70 °C
  • Temp Change from Last Internal Cal = 1 °C
  • Number of Readings = 100
  • Coverage Factor = 3 σ

For example, on the ±10 V range, the absolute accuracy at full scale is as follows:

  • Gain Error = 115 ppm + 11 ppm * 1 + 5 ppm * 70
  • Gain Error = 476 ppm
  • Offset Error = 20 ppm + 44 ppm * 1 + 76 ppm
  • Offset Error = 140 ppm
  • Noise Uncertainty = (237 μV * 3) / √100
  • Noise Uncertainty = 72 μV
  • Absolute Accuracy = 10 V * 476 ppm + 10 V * 140 ppm + 72 μV
  • Absolute Accuracy = 6,231 μV, rounds to 6,230 μV

Measurement Category

Measurement Category I

Caution Do not connect the NI-9205 with DSUB to signals or use for measurements within Measurement Categories II, III, or IV.
Attention Ne pas connecter le NI-9205 with DSUB à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.
Warning Do not connect the NI-9205 with DSUB to signals or use for measurements within Measurement Categories II, III, or IV, or for measurements on MAINs circuits or on circuits derived from Overvoltage Category II, III, or IV which may have transient overvoltages above what the product can withstand. The NI-9205 with DSUB must not be connected to circuits that have a maximum voltage above the continuous working voltage, relative to earth or to other channels, or this could damage and defeat the insulation. The NI-9205 with DSUB can only withstand transients up to the transient overvoltage rating without breakdown or damage to the insulation. An analysis of the working voltages, loop impedances, temporary overvoltages, and transient overvoltages in the system must be conducted prior to making measurements.
Mise en garde Ne pas connecter le NI-9205 with DSUB à des signaux dans les catégories de mesure II, III ou IV et ne pas l'utiliser pour des mesures dans ces catégories, ou des mesures sur secteur ou sur des circuits dérivés de surtensions de catégorie II, III ou IV pouvant présenter des surtensions transitoires supérieures à ce que le produit peut supporter. Le NI-9205 with DSUB ne doit pas être raccordé à des circuits ayant une tension maximale supérieure à la tension de fonctionnement continu, par rapport à la terre ou à d'autres voies, sous peine d'endommager et de compromettre l'isolation. Le NI-9205 with DSUB peut tomber en panne et son isolation risque d'être endommagée si les tensions transitoires dépassent la surtension transitoire nominale. Une analyse des tensions de fonctionnement, des impédances de boucle, des surtensions temporaires et des surtensions transitoires dans le système doit être effectuée avant de procéder à des mesures.

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.

Note Measurement Categories CAT I and CAT O are equivalent. These test and measurement circuits are for other circuits not intended for direct connection to the MAINS building installations of Measurement Categories CAT II, CAT III, or CAT IV.

Measurement Category II

Caution Do not connect the NI-9205 with spring terminal to signals or use for measurements within Measurement Categories III or IV.
Attention Ne pas connecter le NI-9205 with spring terminal 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.
