Taking Measurements - VOLTCRAFT KBM-700 Bedienungsanleitung

3. Press the
the LCD display (8).
4. Prepare the calibration solution with a conductivity of 1413 μS/cm.
5. Keep the measurement probe in the air and check that 0 µS/cm is displayed. If so, calibrate
the probe in the calibration solution.
6. Use the probe to stir the solution for a while to remove air bubbles and then wait without
stirring until a stable value is displayed on the LCD display.
7. To start the calibration process, press and hold the
until the calibration symbol "CAL" (B) appears on the LCD display (6). The value 1413 µS/
cm for the calibration solution will start to flash on the LCD display. The display will stop
flashing and show "SA" followed by "End". The calibration process is now complete. The
meter will automatically revert to measuring mode. If the calibration process fails, "Err" will
be displayed instead of "SA".
8. If 0 µS/cm was not displayed during the air test, calibrate the measurement probe in the air.
To do this, follow the above steps without submerging the probe in the calibration solution.
Once you have completed these steps, calibrate the probe with the calibration solution.
If you wish to measure a liquid with a high conductivity, use a calibration solution with
a conductivity of 12.88 mS/cm.
The standard calibration points for the conductivity are 0 μS/cm, 84 μS/cm, 1413 µS/
cm, 12.88 mS/cm and 80.0 mS/cm.
9. When you have finished calibrating, rinse the measurement probe with clean, distilled water
and wipe it dry.
h) Taking measurements
Always ensure that the correct measurement probe is connected.
1. Remove the soaking bottle from the measurement probe.
2. Rinse the measuring probe with distilled water before measuring and wipe the probe dry.
3. Press the
4. Select "PH", "ORP", "COND", "TDS", or "Salt" mode by pressing the
corresponding symbol appears on the LCD display (8).
5. Dip the tip of the measuring probe approx. 2 - 3 cm into the liquid that you want to measure.
Move the tip of the measuring probe back and forth in the liquid slightly in order to remove
any air bubbles from the surface of the membrane and to stabilise the measurement. It may
take a while for the measurement to stabilize.
