Manual / Automatic Temperature Compensation
(for pH measurements only)
Ph measurements are most accurate when the temperature of the solution under test is known and
a temperature compensation factor is applied to the measurement. This is achieved using Manual
or Automatic Temperature Compensation.
For Manual Temperature Compensation, the external temperature probe is not connected to the
meter and the temperature of the solution under test is manually entered in the Setup Mode. The
temperature entered is shown on the lower LCD line.
For Automatic Temperature Compensation, the external probe is connected to the meter and
inserted into the solution to be tested. The measured temperature of the solution is displayed on the
LCD.

readings for later recall.
1.
Press the MAX-MIN button momentarily to access this mode of operation (REC icon appears)
The meter is now recording the MAX and MIN readings.
2.
Press the MAX-MIN button again to view the current MAX readings (MAX icon appears). The
readings on the display are now the highest readings encountered since the REC icon was
switched on (when the MAX-MIN button was first pressed).
3.
Press the MAX-MIN button again to view the current MIN readings (MIN icon appears). The
readings on the display are now the lowest readings encountered since the REC icon was
switched on (when the MAX-MIN button was first pressed).
4.
