Page 6: Switch Maintenance
Verify that all connections to the device are secure. • Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets. NI 6738/6739 Calibration Procedure | © National Instruments | 5... -
Page 7: Device Setup
Keep connections to the device as short as possible. Long cables and wires can act as antennae, which could pick up extra noise that would affect measurements. • Verify that all connections to the NI 6738/6739 are secure. • Use shielded copper wire for all cable connections to the device. Use twisted-pair wire to eliminate noise and thermal offsets. -

Page 23: Counter Verification
You have finished verifying the analog output levels on your device. Counter Verification NI 6738/6739 devices have only one timebase to verify, so only Counter 0 needs to be checked. It is not possible to adjust this timebase, so only verification can be performed. - Page 24 If the counter verification procedure determines that the device is outside of the limits, refer to the Worldwide Support and Services section for assistance in returning the device to NI.

Page 25: Adjustment
Adjustment The following procedure adjusts the analog output of your NI 6738/6739. At the end of each calibration procedure, these new constants are stored in the external calibration area of the EEPROM. These values are password-protected, which prevents the accidental access or modification of any calibration constants adjusted by the metrology laboratory. -
