Introduction
What Is Calibration?
Calibration
consists of verifying the measurement accuracy of a device and
adjusting for any measurement error. For the NI 6601/6602, calibration is
simply verifying the measurement accuracy of the crystal oscillator on the
device because the crystal oscillator is not user-adjustable.
Verification
is
measuring the performance of a device and comparing these measurements
to the factory specifications. If the device fails after calibration, return it to
NI for repair or replacement. For more information about how to contact NI
for repair or replacement, refer to the
Technical Support Information
document.
Why Should You Verify?
The accuracy of timing components drifts with time and temperature,
which can affect measurement accuracy. Verification determines whether
the device still meets NI standards.
How Often Should You Verify?
Calibrate the NI 6601/6602 at a regular interval as defined by the
measurement accuracy requirements of your application. NI recommends
that you perform a complete calibration at least once every year. You can
shorten this interval based on the accuracy requirements of your
application.
