OPERATIONAL GUIDE
•To switch ON and OFF: press ON/OFF/MODE.
•To freeze the display: press SET/HOLD until “HOLD“ appears.
•To take measurements: connect the probe when the meter is off,
remove the protective cap, turn the meter ON, insert the probe tip in the
sample and wait until the “Not Stable” tag is turned off.
•To enter the pH Calibration mode: press ON/OFF/MODE until “CAL“
appears. Release the button and “pH 7.01 USE” (or “pH 6.86 USE”)
message is displayed.
•To select °C or °F unit: press ON/OFF/MODE until “TEMP“ appears,
then select the temperature unit with SET/HOLD. Press ON/OFF/MODE
twice to return to normal mode.
•To change the calibration buffer set: press ON/OFF/MODE until
“TEMP“ appears. Press again ON/OFF/MODE: the message “pH 7.01
BUFF” (or “pH 6.86 BUFF”) appears. Change the buffer set with SET/
HOLD.Press ON/OFF/MODE to return to normal mode.

pH CALIBRATION PROCEDURE
Calibration messages:
•USE : default suggested buffer.
•REC : a valid buffer is recognized.
•WRNG : invalid buffer detected.
Two-point procedure:
•Place the probe in pH 7.01 (or 6.86) buffer.
•After the first point is accepted, the “pH 4.01 USE” message appears.
•Place the probe in pH 4.01, 10.01 (or 9.18) buffer.
•When the second point is accepted, the “OK 2” message appears and then
the meter returns to normal mode.
Single-point procedure:
•With pH 4.01, 9.18 or 10.01 buffer: when the calibration point is
accepted, the buffer value and “OK 1” message appear and then the meter
returns to normal mode.
•With pH 7.01 or 6.86 buffer: after the calibration point has been
accepted, the ON/OFF/MODE button must be pressed to return to normal
mode.
NOTES
•Probe: FC 214D pH electrode with internal temperature sensor, titanium
body, for Beer Industry, with DIN connector.
•If the probe is dry, soak it in HI 70300 Storage Solution for half an hour.
•To clean the meter: use water.
•To quit calibration (ESC): press ON/OFF/MODE after entering the
calibration mode and before the first point is accepted.
•To clear calibration (CLR): press SET/HOLD after entering the calibration
mode and before the first point is accepted.
•When the battery symbol
- +
appears, the batteries should be replaced
soon.
•Open the battery compartment cap on the bottom of the instrument and
replace old batteries with new ones, following the instructions on the rear of
the instrument.
