PH 4.00 : 97mV..... 250mV
PH 7.00 : - 60mV..... 60mV
PH10.00 : - 250mV..... -97mV
Acceptable voltage range of each point:
5. If the probe recognizes the buffer:
If the probe successfully recognizes the
buffer, the buffer pH value (4 or 7 or 10)
will appear on the display in 2 seconds.
If the calibration buffer is not 4,7,10 but
another value, such as 4.01, just
press " " to change the value.

7. To save the calibration value:
When the electrode reads a stable value
and user stops pressing any keys, the
meter will automatically save the value
and then escape the calibration mode.
6. The adjustable cal. point range for 4.0
pH is from 3.50 to 4.50. For 7.0 pH is
from 6.50 to 7.50. For 10.0 pH is from
9.50 to 10.50
