4.3 Taking Measurements
Be sure to remove any electrode soaker bottle or protective rubber cap from the electrode before measurement.
To take readings:
1. Rinse the electrode with distilled or tap water before use to remove any impurities adhering to the electrode body. If
the pH electrode had dehydrated, soak it for 30 minutes in EC-RE005/ 00653-04 electrode storage solution. (See
Electrode Care - Section 6)
2. Press ON key to switch on meter. The [MEAS] annunciator appears on the top center of LCD. The ATC annunciator
appears in the lower right hand corner to indicate ATC if a temperature probe is plugged. (For MTC, refer to Section
4.2).
3. Dip the electrode and temperature probe into the sample, making sure that the glass bulb of the electrode must be
completely immersed into the sample. Stir the probes gently to create a homogeneous sample.
4. Allow time for reading to stabilize. When the readings stabilize, a [READY] annunciator displays. The READY mode
shows the readings are stable within a range of ±0.01 pH. When this occurs, the [READY] annunciator appears on
the top left side of LCD. Take the reading.
5. To toggle between pH and mV in the pH510, or to toggle between pH, mV and Ion in the Ion 510, press the MODE
key.
