USE
Automatic shutdown
If you do not press any key for 8 minutes, the meter will automatically turn off.
Calibration
Calibrate the meter before first use or after replacement of the electrode. We also advice
to calibrate the meter twice a week if you frequently use the meter. If you only use the
meter occasionally you need to calibrate the meter before each use.
1. Press MEAS to switch the meter on.
2. Thoroughly rinse the meter with distilled water (by stirring a couple of times in a glass).
Briefly dry with filter paper.
3. Press and hold CAL until the display shows ‘CAL 4-7’. Press ‘CAL’ again to calibrate at pH 7.00 and
pH 10.00, display will show ‘CAL 10-7’.
4. Press ENTER, ‘CAL 7’ appears.
5. Immerse the electrode approximately 2-3 cm in a pH 7.00 calibration solution and gently stir.
6. Press ENTER again. The meter starts to calibrate. The read-out will flash 3 times when it has
stabilised. This is the pH value at the present temperature.
7. The calibration at pH 7.00 is completed. Subsequently ‘CAL 4’ appears.
Repeat steps 5 and 6 as explained above, but this time with pH 4.00 buffer
solution. This pH meter has a built-in function for automatic temperature
compensation starting from 0 to 60°C. The pH meter will automatically
compensate the measured value.
