Conductivity Mode
1. Rinse electrodes thoroughly by
agitating in distilled or deionized
water.
2. Wipe off conductivity electrode and
allow it to dry.
3. When dry, conductivity should read
“0” in air.
4. Adjust ZERO pot if reading is
incorrect. If the conductivity
electrode does not zero, it may
indicate dried solids on the sensor.
Clean with a mild detergent solution
(such as Ivory).
5. Immerse electrode in a known
conductivity solution. Choose a
conductivity calibration solution that
is near the range of the samples to
be measured. Adjust SPAN pot to
desired conductivity value.
6. Rinse electrodes and return to
storage compartment.
Operating Procedure
The 9 volt battery should already be
installed
1. Extend electrode pair to either the
90° or 180° measurement position.
2. Remove the electrode covers as
described in “Setting Up the
Electrodes” section.
3. Turn on the instrument by pressing
the ON/OFF switch once.
“–1” and the unit of measure will
momentarily appear and then a second
number with the unit of measure is
displayed. The display should show
which parameter is being measured (for
example, pH, µS (micro-siemens), or
µS x 10. Only the 200K range utilizes the
x10 annunciator on the PHH-80. 20K and
2K are direct readings.
