Note: Pressing the CAL key again will change the required buffer value, making possible a single point cali- bration at pH 4.01 or pH 10.01.
•Wait till the hourglass symbol on the display turns off and the “pH” tag stops
blinking, then press the CFM key to confirm the off- set calibration. “pH 4.01” will flash on the LCD.
•Rinse the pH electrode and the temperature
probe in the first pH4.01 beaker, then immerse them into the second pH4.01 beaker.
• | Follow the same procedure if using the |
| pH10.01 solution; select the correct |
| buffer by pressing the CAL key. |
• | Wait till the hourglass symbol on the |
| LCD turns off, then press the CFM key |
BATTERY REPLACEMENT:
When the battery becomes so weak that no reliable measurement can be guaran- teed, the meter will display “Eb” for a while and then turns off.
It is recommended to replace immediately the battery.
Battery replacement must only take place in a
Turn the meter off, slide off the battery compart- ment cover at the rear of the meter and replace the 9V battery with a new one.
Make sure the battery contacts are tight and secure, seat the battery in its compartment and insert back the cover.

Notes:
•To exit the calibration mode, turn the meter off by pressing the ON/OFF key.
•To perform a single point calibration (offset) at pH7.01, press the ON/OFF key when the second buffer is asked.
•After battery replacement, the meter dis- plays the “Clr” message and recalibration is needed.
