This information can be checked and the date, time, calibration or
alarm settings may be adjusted prior to performing a measurement.
(See sections on Setup, Calibration, and Set Alarms)
The calibration due date is set to occur thirty days after the last
calibration. However, calibration may be performed at any time
before this date to improve measurement accuracy. Measurements
can be made after the calibration due date has passed but
consideration must be given to the gas sensors which exhibit a slow
decline in sensitivity over time. This loss of sensitivity is typically
less than 2% per month but could be more if they are exposed to
adverse conditions such as exposure to gas concentrations above
the measurement range or to solvents such as alcohol.
If the calibration due date has passed then the following reminder
will be displayed both after the introductory screen and when
commencing measurement:
Once ENTER is pressed the first menu is displayed and allows
