7.4 Manual Temperature Setting
If the Conductivity/Temperature sensor is not connected, and a
temperature sensor is not used in its place, the temperature of the sample
solution must be set manually for accurate pH measurements. A separate
thermometer will be required for this.
NOTE: The Conductivity sensor has a separate sensor built in for
automatic temperature compensation for Conductivity, TDS and
Salinity.
1. Switch the meter on.
2. Measure the temperature of the sample.
3. Select Temperature Calibration. ( F1:Cal. F3:Temp)
4. The current temperature setting is now displayed.
25.0 Man Temp
:Set F1:Save
5. Press the and keys until the display shows the temperature of
the sample.
6. Press the key to save the temperature value.
Alternatively, press the key to quit and retain the current setting.
