The 2500 series retains history entries (up to 20 per category) for the following events.
The most recent event is shown first.
Alarms: An entry is made each time an alarm appears (‘ON’) or is cleared (‘OFF’),
in the following format:
[Measurement] [Alarm No.] [Event] [Time] [Date]
Go via MENU/ALARMS to ALARM HISTORY - Press ENTER

NOTE
Sometimes one or two faults may be logged for a moment on power up. This is a normal
occurrence.
Calibration: Each measurement has its own calibration history for ZERO and
SPAN. An entry is made each time a calibration or calibration check is
performed, in the following format:
[Measurement] [Type*] [Difference**] [Time] [Date]
* ‘Type’ is the type of calibration performed, CHECK or CAL and ZERO or SPAN.
** In the case of CHECK operations, the ‘difference’ is (2500 reading) - (Calibration
Sample Concentration). Any constant value therefore shows NO drift.
In the case of CALIBRATION operations, the ‘difference’ is (2500 reading before
correction) -(Calibration Sample Concentration). Any constant value therefore shows a
CONSTANT drift.
