Verification; Analog Output Verification - National Instruments NI 6738 Calibration Procedure

Note You also can read the current device temperature, the temperature during the
last self-calibration, and the temperature during the last external calibration in MAX.
Launch MAX, select My System»Devices and Interfaces»your device, and then
click the Calibration tab. Temperature information is displayed Self-Calibration and
External Calibration sections of the Settings tab.

Verification

The following performance verification procedures describe the sequence of operation and
provide test points required to verify the NI 6738/6739. The verification procedures assume that
adequate traceable uncertainties are available for the calibration references.
The verification procedure is divided into the major functions of the device. Throughout the
verification process, use the tables in the
to be adjusted. These tables show all acceptable settings for the device.

Analog Output Verification

The NI 6738 has 32 analog outputs, AO <0..31>. The NI 6739 has 64 analog outputs, AO <0..63>.
Note Table 7,
edition of the specifications document for your device. Refer to the most recent
specifications document online at
Note The test limits used in this document assume a maximum temperature drift of
±10 °C from the last external calibration, and a maximum temperature drift of ±1 °C
from the last self-calibration. Refer to the
section for more information and instructions on reading your device temperature and
comparing it against the device temperature during the last external calibration.
Notice
simultaneously, as the multiple signal connections will produce noise that can affect
measurements.
Complete the following steps to check analog output measurements.
1. Connect your DMM to AO 0 as shown in Table 5,
DAQ switch fixture, configure your connections as shown in Table 6,
Connection Details.
Note If you are using the NI 4070, ensure that it is set to the 10 V range.
