GENERAL DESCRIPTION and INTENDED USE
The HI99161 is a portable, lightweight meter with two
button operation that is simple to use. It is designed
specifically for use in the food sector. Features include 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 meter is supplied with a pH electrode specially designed
for use in the food sector.
The FC2023 pH electrode has a built‑in temperature sensor
for simultaneous temperature compensated pH and tem‑
perature readings, and also contains an integral preamplifier
to provide measurements impervious to noise and electrical
interferences.
TheFC2023 isapenetrationstyle pH electrode with aconical
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.

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“).
TO CONNECT 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.
TO TURN 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, fol‑
lowed 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 fouled, 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.

TO SELECT THE MEASUREMENT RANGE
While in measurement mode, press the SET button to select
pH or pH‑mV measurement on the first LCD line.
TO FREEZE THE 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.
TO ENTER CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “STD“ and tag. Release the button.
TO ENTER SETUP MODE
Press and hold button until “STD“ and tag is
replaced by “SETUP“ and tag. Release the button.
TO TURN THE METER OFF
Whileinmeasurementmode,pressthe button.”POWER”
and tag will appear. Release the button.
