Please note the data and test values specified in the leaflet
accompanying the calibration ampoules.
Break off the head of the ampoule. Take the calibration block in your
hand so that you can push in the calibration ampoule from the
bottom. Then place the calibration block on a level surface and make
sure that the calibration fluid runs into the calibration block. Now
insert the sensor head of the measuring instrument into the calibration
block carefully as far as it will go.
Wait two hours (acclimatisation time) before performing the cali-
bration according to the one-point calibration procedure described
under “CAL”.
Remove the sensor head from the calibration block. Dispose of the
ampoule and clean the calibration block with distilled water.
Important:
Only use the calibration ampoules once. The tempera-
ture may not change during the acclimatisation time. Only calibrate
at room temperatures of 20 to 21 °C. Calibrations may only be
made with suitable reference values and by trained personnel.
