pH measurement

• Auto stability mode
If the measurement pH value does not fulfill the stability condition, the fixed value is
released. When the measured value fulfill the stability condition again, the measured
value is fixed.
• Auto hold mode
Press the key to release the fixed measured value. When the measured value
fulfill stability condition again, the measured value is fixed.
Note
・
The criteria of stability judgment in the auto hold measurement are as follows.
Potential variation for 10 seconds is less than 1 mV (0.015 pH equivalent) and
temperature variation is less than 2.0°C
・
If the measured value is below the display range, "Ur" (under) appears. If the measured
value is above the display range, "Or" (over) appears. For details on the action to take,
refer to "The measured value is out of the measurement range" (page 92).
●
