Hanna Instruments HI 99161 - Waterproof PH Meter Manual

INTRODUCTION

The meter is supplied with a pH electrode specially designed for use in the food sector.
FC 202D pH electrode with built-in temperature sensor, features a rugged, easy to clean, PVDF body with a strong conic tip ideal for measurements in semisolids such as meats and cheeses. The electrode is also provided with a free diffusion sleev type reference junction which prevents the typical problems of clogging in viscous liquids such as milk or condiments.

Display OVERVIEW

OPERATIONAL 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 device 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 sec- onds, followed by a percent indication of the remaining bat- tery 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 device 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 succes- sively, clean the probe tip thoroughly to eliminate cross- contamination. For cleaning procedure choose the suit- able 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.

DEVICE SETUP

Press and hold the ON/OFF/MODE button for about 6 sec- onds, 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 temperature 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.
