5.3 Taking Measurements
To take readings:
1.
Rinse the probe with DI or distilled water before use
to remove any impurities adhering to the probe
body. Shake or air dry. To avoid contamination or
dilution of your sample, rinse probe with a small
volume of your sample liquid.
2. Press ON to switch on meter and the MEAS
annunciator appears on the top center of the LCD.
3. Dip the probe into the sample.
When dipping the probe into the sample, take care to ensure that the liquid
level is above its upper steel band. Stir the probe gently in the sample to
create a homogenous sample.
4. Allow time for the reading to stabilise. Note the reading on the display.
5. Press the MODE key to toggle between conductivity and TDS readings.
Taking measurements with READY indicator selected on
If the READY indicator has been activated, the READY annunciator lights when the reading is
stable. Switch the READY indicator on or off in SETUP program P 4.1. See page 30 for
directions.
Taking measurements with the auto endpoint feature selected on
When a reading is stable for more than 5 seconds, the auto endpoint feature will automatically
“hold” the reading. The “hold” indicator appears on the left side of the display. Press the HOLD
key to release the reading. Switch the Auto endpoint feature on or off in SETUP program P 4.1,
see page 30 for instructions.
