Point 3 - palintest Macro 900 Operation Manual

Macro 900 Operation Manual
(Pt-2) is the warm 100ppm point. Calibration point 3 (Pt-3) is the cool
10ppm point.
The dates shown to the right of each point are the dates of the last
successful calibration.
8. Select Pt-1. The screen will change to:
The Meter will wait until the readings are stable, then it will send the calibration
command to the Probe, where the calibration takes place. During calibration,
the Calibrating screen is displayed and the progress counter counts up. If the
calibration is successful, the counter will reach 100% and the following screen
will be displayed.
The Calibration Report on the top line displays the voltage output from the ISE
electrode in millivolts (mV). This value is not stored in memory so should be
noted down in a calibration record book for the probe along with the
temperature.
Point 2
1. Remove the probe from the 10ppm solution and wash thoroughly in
deionised water. Dry the probe then drop it into to the warm 100ppm
solution.
2. Stir the probe until the temperature and NH4 readings are completely
stable. A minimum of five minutes is recommended.
3. Ensure the temperature of the solution is within 1ºC of the
previous 10ppm calibration point. If the solution is warmer or cooler
than this, calibration will fail.
4. Referring to steps 4-7 above, select Pt-2 and press OK.
The Meter will wait until the readings are stable, then it will send the calibration
command to the Probe, where the calibration takes place. During calibration,
the Calibrating screen is displayed and the progress counter counts up as
shown above. If the calibration is successful, the counter will reach 100% and
the calibration report screen will be displayed.
If the temperature of the 100ppm solution is more than 1ºC different from the
Pt-1 calibration temperature, an OUT OF TEMP RANGE calibration error will be
