The READY indicator appears on the display when
the readings stabilise. It will turn off if the readings
start to fluctuate.
NOTE: Be sure to remove the protective cap of the
pH electrode before measurement.
To take readings:
1. Rinse the probe with DI water before use to
remove any impurities adhering to the probe
body. If the pH electrode has dehydrated,
soak it for 30 minutes in tap water.
2. Switch on the meter. The MEAS annunciator
appears on the top center of the LCD. The
ATC indicator appears in the lower right hand
corner to indicate Automatic Temperature
Compensation. See Figure 22.
3. Dip the probe into the sample.
NOTE: When measuring a sample, make sure that
the probe is immersed beyond the electrode band.
See figure in Section 4.2. Stir the sample using the
probe gently to create a homogenous sample. Allow
time for the readings to stabilize. Note the readings
on the display. When the readings are stable, the
READY annunciator appears.
4. To toggle between pH and conductivity
readings, press the MODE key. See Figures
23 and 24.
NOTE: Conductivity readings are auto
ranging and will automatically move to
the correct range (four ranges
possible).
