4.6. Calibrating for Conductivity:
1. Pour out two separate portions of your calibration
standard and one of DI water into separate clean
containers.
2. If necessary, press MODE key to select
Conductivity Mode. The
PS and mS indicator will
appear on the right side of the display.
3. Rinse your probe with DI water, then rinse the
probe in one portion of the calibration standard.
Immerse the probe into the second portion of the
calibration standard. The meter auto ranging
function selects the appropriate conductivity range
(four ranges are possible). Be sure the probe is
free from air bubbles and sufficient calibration
standard is used to cover the conductivity sensor.
Wait for the reading to stabilize. The READY
indicator lights when the reading is stable.
See Figure 18
4. Press the CAL/MEAS key. The CAL indicator
appears above the primary display. The primary
display shows the measured reading and the
secondary display shows the temperature.
See Figure 19.
5. Press the ź or Ÿ key to scroll to the value of your
conductivity standard. Press and hold the ź or Ÿ
keys to scroll faster. See Figure 20.
