Taking Measurements; Using Manual Ranging Function - LaMotte 6 Series Manual

Taking Measurements

1. Rinse the probe with deionized or distilled water before use to remove any
impurities adhering to the probe body. Shake or air dry. To avoid
contamination or dilution of the sample, rinse the probe with a small
volume of the sample liquid.
2. Press ON to turn the meter on.
3. Dip the probe into the sample.
4. Allow time for the reading to stabilize. Note the reading on the display.
NOTE: When dipping the probe into the sample, take care to ensure that the
liquid level is above the upper steel band. Gently stir the sample with the
probe to create a homogenous sample.

Using Manual Ranging Function

By default the meter has auto-ranging ability and will automatically select the
range in which the readings appear.
However, a specific range may be selected. This is achieved by pressing
button successively for each measurement range. The five ranges are:
Conductivity
Range (CON 6)
0 – 20.00 µS/cm
0 – 200.0 µS/cm
0 – 2000 µS/cm
0 – 20.00 mS/cm
0 – 200.0 mS/cm
TDS Range (TDS 6)
(if TDS factor is 0.5)
0 – 10.00 ppm
0 – 100.0 ppm
0 – 1000 ppm
0 – 10.00 ppt
