OPERA TIONAL GUIDE
To connect the probe
Connect the FC 202D probe to the DIN socket on the top of
the meter by aligning the pins and pushing in the plug. Tighten
the nut to ensure a good connection. Remove the protective
cap from the probe before taking any measurements.
To turn the meter on and to check battery status
Press and hold the ON/OFF/MODE button for 2 seconds. All
the used segments on the LCD are visible for a few seconds, followed by a percent indication of the remaining battery life (e.g. % 100 BATT).
To freeze the display
Press and hold the SET/HOLD button, until HOLD appears
on the bottom display. The reading will be frozen on the LCD
(e.g. pH 5.73 HOLD).
Press any button to return to normal mode.
To turn the meter off
From normal measuring mode, press ON/OFF/MODE. OFF
appears on the bottom display. Release the button.
pH MEASUREMENT & CALIBRATION
• Make sure the meter has been calibrated before use.
• If the electrode has been left dry, soak it in HI 70300 storage solution for one hour to reactivate.
• Insert the tip of the probe in the sample to be tested.
• Wait until the stability indicator on the LCD is turned off.
• The LCD shows the pH value automatically compensated
for temperature and the temperature of the sample.
• If measurements are taken in different samples successively, clean the probe tip thoroughly to eliminate crosscontamination. For cleaning procedure choose the suitable Hanna cleaning solution (see “Accessories” section).
pH calibration
• Press and hold the ON/OFF/MODE button, until OFF on the
bottom display is replaced by CAL.
• Release the button. The LCD displays “pH 7.01 USE” or
“pH 6.86 USE” (if you selected the NIST buffer set).
• For a single point pH calibration, place the probe in any
buffer from the selected buffer set (eg. pH 7.01 or pH 4.01
or pH 10.01). The meter automatically recognizes the buffer
value and displays OK for 1 second.
If the pH 7.01 buffer (or 6.86 if you selected the NIST buffer
set) was used, press the ON/OFF/MODE button to return to
the pH measuring mode.
• For a two point pH calibration, place the probe in pH 7.01
(or 6.86, if you selected the NIST buffer set). The LCD displays the recognized buffer value and OK for 1 second and
then “pH 4.01 USE”.
Place the probe in the second buffer solution (pH 4.01 or
10.01, or, if using NIST, pH 4.01 or 9.18). When the second
buffer is recognized, the LCD displays OK for 1 second
and the meter returns to normal measuring mode.
To reset to the default calibration
To clear a previous calibration, press the ON/OFF/MODE
button after entering the calibration mode. The bottom LCD
displays ESC for 1 second and the meter returns to normal
measuring mode. The “CAL” symbol on the LCD disappears
and the meter resets to the default calibration.
METER SETUP
• Press and hold the ON/OFF/MODE button for about 6 seconds, until CAL on the bottom display is replaced by TEMP
and the current temperature unit (e.g. TEMP °C). Then:
• for °C/°F selection, use the SET/HOLD button. After the
temperature unit has been selected, press ON/OFF/MODE
to enter the buffer set selection mode; press ON/OFF/MODE
twice to return to the normal measuring mode.
• to change the calibration buffer set, after setting the tem-
perature unit, the meter will show the current buffer set: pH
7.01 BUFF (for 4.01/7.01/10.01) or pH 6.86 BUFF (for 4.01/
6.86/9.18). Change the set with the SET/HOLD button, then
press ON/OFF/MODE to return to normal mode.
BATTERY REPLACEMENT
The meter displays the remaining percentage when turned
on. When the battery level is below 5%, the
- +
symbol on the
bottom left of the LCD lights up to indicate a low battery condition. If the battery level is low enough to cause erroneous
readings, the Battery Error Prevention System (BEPS) turns
the meter off.
The batteries are accessed by separating the front and back
halves of the meter. Unscrew the 4 screws located on the
back of the meter. Remove the back and carefully replace all
the four AAA batteries located in the battery compartment,
while paying attention to their polarity.
Re-attach the back, making sure that the gasket is in place to
ensure a watertight seal.
