Acceptable voltage range of each point:
pH 4.00 : 97 mV..... 250 mV
pH 7.00 : - 60 mV..... 60 mV
pH10.00 : - 250 mV..... -97 mV
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 7.01, just
press “ “ to change the value.
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
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.
