Macro 900 Operation Manual
The Calibration Report on the top line displays the voltage output from the
probe in millivolts (mV). This value is not stored in memory so should be noted
down in a calibration record book for the probe.

Calibrating Point 2
Remove the Probe from the calibration bottle, shake off any excess water then
dry the outer sleeve with a soft cloth.
Fill a calibration bottle with freshly mixed Fluorescein calibration solution and
drop the Probe in all the way.
Again, bang the Probe against the bottom of the bottle several times in order to
remove any air bubbles that may be clinging to the probe.
Follow the procedure detailed above for Zero point calibration as far as step 6,
then select Pt-2. Wait while the Meter stabilises and calibrates.
After successful calibration, the 'Calibrating 100%' screen will be displayed
along with the Calibration Report, which will show the voltage output from the
probe in millivolts (mV). Press the OK key to continue.
Calibration is now complete.

Lens and Sleeve Maintenance
On a daily basis, the lenses on the probe should be wiped over with a soft damp
cloth.
Similarly, the inside of the Probe Sleeve and Sleeve Cap should be kept clean
and free from any deposits that may cause stray fluorescence.
Never use an abrasive cleaner on the inside of the Probe sleeve or cap
as they have been treated with a non-reflective coating which can be
easily damaged. The inside of the sleeve should be wiped over with a soft
damp cloth and non-abrasive detergent.
Always re-calibrate the zero point after cleaning the sleeve or lenses.
