Milwaukee MC810 Bedienungsanleitung

TDS CALIBRATION (MC810 with MA811 probe)
Preparation
Always use fresh calibration solutions and perform
electrode maintenance prior to calibration.
Calibration can be performed using one of the standard
solutions: 1382 ppm for TDS factor 0.5 or 1500 ppm for TDS
factor 0.7.
If possible, use plastic beakers to minimize any EMC
interferences. For accurate calibration and to minimize
cross-contamination, use two clean beakers, one for rinsing
the probes and one for calibration.
Pour sufficient calibration solution to cover the sensing
portion of the probes (4 cm / 1 ½").
Procedure
1. Immerse the probes in the rinse beaker. Raise and lower
several times to ensure the entire cell area is filled with
solution. Discard this solution.
2. Pour calibration solution into the calibration beaker.
3. Dislodge any bubbles off the two electrodes (prongs).
4. Center the probes in beaker away from beaker walls.
5. Wait a few minutes for the measurement to stabilize.
6. Use the calibration screwdriver to adjust the ppm trimmer
until the reading shows "1380" ppm (with factor 0.5) or
"1500" ppm (with factor 0.7).
EC CALIBRATION (MC811 with MA812 probe)
Follow the TDS calibration procedure steps and use
1413 µS/cm (M10031 ) calibration solution.
When the mS readout shows "1.41", calibration is complete.
MEASUREMENTS
1. Remove the pH electrode protective cap.
2. Immerse the tips of the probes at least 4cm (1½") into the
sample. Center the probes in beaker away from beaker walls.
4 cm
(1 ")
3. The three readouts will display all parameters values
simultaneously.
Note: Initial variation in readings may be due to the pH
electrode conditioning and to the temperature compensation
of TDS / EC measurements. Allow readings to stabilize!
CARE & MAINTENANCE
pH Probe
 Inspect the BNC connector for corrosion. Replace the probe
if necessary.
 Inspect the electrode for scratches or cracks. If any present,
replace the probe.
 Remove the protective cap. If the bulb or junction are dry,
soak in MA9015 Electrode storage solution overnight.
If any salt deposits are present, rinse the probe with water.
 To ensure a quick response, the glass bulb and the junction
should not be allowed to dry. Store the electrode with a
few drops of MA9015 storage solution (or MA9004, pH 4.01
buffer solution) in the protective cap.
 Clean the electrode (at least once a week) by soaking it
for 30 minutes in MA9016 Electrode cleaning solution (or
M10016).
 After cleaning, rinse with tap water, then soak the electrode
in MA9015 storage solution for one hour before calibration.
 Never use distilled or deionized water to store pH electrodes.
TDS & EC Probes
Clean the sensor (at least once a month) by soaking it for 30
minutes in MA9016 Electrode cleaning solution (or M10016).
For a more thorough cleaning:
1. Clean the pins with fine sandpaper to loosen any debris.
2. Flush with tap water after cleaning.
After every series of measurements, rinse with tap water.
