GENERAL DESCRIPTION AND INTENDED USE
GENERAL DESCRIPTION AND INTENDED USE
The HI99161 portable pH meter together with a FC2023
combination pH electrode, is designed to measure the pH of
food and dairy products.
The HI99161 has a waterproof and compact casing, large
dual‑line display, low battery detection, automatic pH
calibration at one or two points and selectable temperature
unit (°C or °F).
The FC2023 is a penetration style pH electrode with a
conical sensing tip and features an easy to clean, PVDF
body and double junction gel filled reference with a free
diffusion sleeve style reference junction. The electrode
is ideal for measurements in semisolid foods such as
processed meats, soft cheeses, soups, sauces, condiments,
jams, jellies, dough, ice cream, sushi and rice. The
FC2023 has a built‑in temperature sensor for temperature
compensated pH readings and an integrated preamplifier
to provide measurements impervious to noise and electrical
interferences.

OPERATIONAL GUIDE
OPERATIONAL GUIDE
Each meter is supplied with batteries. Before using the meter
for the first time, open the battery compartment and insert
batteries, observing the polarity (see “Battery Replacement”).
CONNECTING THE ELECTRODE
With the meter turned off, connect the FC2023 probe to the
DIN socket on the bottom of the meter by aligning the pins
and pushing in the plug firmly. Remove the protective cap
from the probe before taking any measurements.
TURNING THE METER ON
To turn the meter ON, press the button on
the front of the meter. If it does not turn on, make
sure that the batteries are properly installed in their place.
The meter is provided with an active acoustic signal when
a key is pressed. At start‑up the meter displays all LCD
segments for a few seconds, followed by the percentage
indication of the remaining battery life, displaying “WAIT“
until electrode check is in process then the meter enters the
normal measurement mode.

Note: The meter detects the presence and the type of
the probe at its input.
- If the probe is not connected the message “NO”
”PROBE“ appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.
- If the readings are out of range, the nearest range limits
are displayed blinking (e.g. -2.00 pH -5.0 °C).

OPERATIONAL GUIDE
pH MEASUREMENT & CALIBRATION
Make sure the meter has been
calibrated before use.
If the probe is dry, soak it in HI70300
storage solution for 30 minutes to
reactivate it. If soiled, clean the
electrode by soaking in cleaning solution for 20 minutes,
then rinse the tip and soak in storage solution at least 30
minutes before use.
Rinse the electrode off well and shake off excess droplets.
Recalibrate before using.
Submerge the probe in the sample to be tested while stirring
it gently. Wait until the tag on the LCD disappears.
SELECTING MEASUREMENT RANGE
While in measurement mode, press the SET button to select
pH or pH‑mV measurement on the first LCD line.
FREEZING MEASUREMENT VALUES
While in measurement mode, press and hold the SET
button until “HOLD“ appears on the secondary LCD. The
“HOLD“ remains for 1 second and reading of pH, mV
and temperature will be frozen on the LCD with“H” blinking.

Press any button to resume active measurements.
ENTERING CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “STD“ and tag. Release the button.
ENTERING SETUP MODE
Press and hold button until “STD“ and tag is
replaced by “SETUP“ and tag. Release the button.
TURNING THE METER OFF
Whileinmeasurement mode,pressthe button.”POWER”
and tag will appear. Release the button.
