7.5.9 SELF-ZEROING

With Self-Zeroing enabled, the instrument re-zeroes automatically if the signal
drifts below the last Zero Calibration for some time.
Notes
Such drift can occur:
• Slowly as the lamp ages
• As dust or oil film accumulates on the lamp window
• As environmental conditions change, such as background matrix gas, humidity or
temperature.
• The default setting of self-zeroing is off.
At the time of enabling self-zeroing, make sure the instrument is running in a clear environment for
several minutes to ensure that the baseline zero signal is well established.
