MICRO/2000® AND DEOX/2000® MODULE
5.1.1 Check for tightness
Check the entire measuring device including all screw connections for
leakage. Repair any leakage points immediately.
NOTE:
Air bubbles in the sample water influence the measuring accuracy.
The cause must be determined and remedied.
5.1.2 Checking the cell sand
Check that there is sufficient sand in the cell body. The cell sand must
be swirled around in the bottom section of the cell body. The cell sand
is necessary for cleaning the chlorine sensor electrodes and must be
replenished or replaced when required. (Refer to section 2.3.2 "Pour in the
cell sand (only with MICRO/2000® and DEOX/2000®)" and "Changing
cell sand with 3-electrode cell MICRO/2000® and DEOX/2000®".)
NOTE:
When fresh sand is replenished, the electrode current may increase
slightly for approximately 3 hours. Do not calibrate during this time. You
must calibrate each time the cell sand is replaced. The calibration must
be checked after one day.
5.2
Maintaining MICRO/2000® and DEOX/2000® Flow Block Assembly
WARNING:
To avoid electrical shock, turn off power before servicing.
WARNING:
To avoid electrical shock or damage to equipment, avoid
contact with circuit board components while making adjustments.
WARNING:
Wear recommended protective eyewear when servicing
the wet components of the analyser, particularly when servicing reagents
and reagent lines. The analyser uses chemicals that can cause severe
personal injury by chemical burns on contact with eyes. Rinse any area
of contact immediately. If chemicals contact eyes, rinse from eyes and
seek immediate medical attention.
5.2.1 Wetside panel removal and replacement
1. Shut off sample flow to the analyser.
2. Disconnect the probe and motor connectors from the SFC electronics,
if those parts will be serviced.
3. Remove the probe and set it carefully aside. Do not rest it on its
electrode end. If the probe will be removed for more than an hour,
place it, with the electrodes, in a beaker of water.
