7.4 Manual Temperature Setting
If a Conductivity/TDS or Temperature sensor is not connected, the temperature of the sample
solution must be set manually for accurate ppM Dissolved Oxygen or pH measurements. A separate
thermometer will be required for this.
1. Switch the meter on.
2. Measure the temperature of the sample.
3. Select Temperature Calibration ( →→ F1:Calibrate →→ F2:Temperature).
4. The current temperature setting is now displayed. For example…
Enter Manual Temperature : 25.0

5. Enter the temperature of the sample, using the Numeric Keypad.
Press to save the new value.
Alternatively, press to quit and retain the current setting.
6. When returning to normal measurement mode, note the “M” in the temperature readout,
indicating that Manual Temperature Compensation is in use. For example…
