3) When the reading is stable and appears
shows End and the meter enters measurement mode.
Perform also Calibration in air at 100%. The calibration remains in memory even after the instrument is
turned off.
Note:
If the
key is pressed when the reading is not stabilized yet, Er2 will appear on the display.
3.3 Calibration interval
The time interval between two calibrations (100% in air) depends on the type of sample, the efficiency of
the sensor and the accuracy sought, it is usually necessary to calibrate the meter at least once a week, for
greater accuracy calibrate the instrument more frequently.
You must recalibrate the instrument if occurs one of the following conditions:
New probe or unused for long time
After replacing the luminophore
3.4 Due calibration – GLP function
On this instrument, you can set an expiration of calibration, after
which the instrument displays an error message, Er 7, and does
not allow new measurements until a new calibration is performed
at 100% in air.
By default this feature is disabled. To activate go to the parameter
P5.1 of setup menu, and set the number of hours ("H00") or days
("d00") indicating the expiration of the calibration. To turn it off,
select "no".
Example:
If we set d02 in P5.3 of setup menu, it means that the instrument will work for 2 days, after which you have to recalibrate in
order to make a new measurement. The same applies for the hours.
3.4.1 Date and time of the last calibration – GLP function
To check the date and time of last calibration access parameter P5.4 of setup menu, if it's been a long
time then recalibrate the instrument in air at 100%.
