INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Slide off the
battery compartment cover on the back of the meter (see page 43),
install the battery while paying attention to its polarity.
Always remove the electrode protective cap before taking any mea-
surements. If the electrode has been left dry, soak the tip (bottom
4 cm/1½") in a pH 7 or pH 4 buffer solution for a few minutes to
reactivate it.
For HI 8014:
Connect the pH electrode to the BNC socket on the top of the meter.
Turn the meter on by turning the rotary knob to the °C, pH or mV
position.
For HI 8314, HI 8915, HI 8424 and HI 9622:
Connect the pH electrode to the BNC socket on
the top of the instrument. Connect the tem-
perature probe to the socket. The temperature
probe can be used independently to take tem-
perature measurements, or it can be used in
conjunction with the pH electrode to utilize the
meter's ATC capability. With
HI 8424
and
HI 9622
, when the probe is disconnected, tem-
perature can also be set manually (see page
22).
Turn the meter on by pressing ON/OFF.
With
HI 9622
, the display will show the previ-
ous calibration date (month & date) for 3
seconds.
For HI 9214:
Connect the pH electrode to the screw type connector on the meter. Be
sure that the electrode and the meter connections are clean and dry
to ensure a positive contact. Turn the meter on by pressing
ON/OFF.
