Temperature Units

Manual Temperature Compensation
In the pH mode, the solution temperature can be measured and set by using the optional
external temperature probe or, when the probe is not used, by adjusting the temperature
display. Press the ▲▼buttons to set the temperature when the MTC icon is displayed.
The Conductivity probe has a built‐in temperature sensor so manual temperature compensation
does not apply for Conductivity measurements.
Auto Power off (APO)
The meter is equipped with an Automatic Power Off feature. The meter will power down after a
10‐minute period of inactivity. This feature can be disabled by pressing and holding the POWER
button for 2 seconds (the APO display icon indicates that this feature is enabled). After disabling
APO, the next time the meter is powered up APO will be re‐enabled.
Reset to Default settings
The meter can be reset to its factory default configuration:
1. With the meter OFF, press and hold the POWER and STORE/RECALL buttons simultaneously
until dFLt rSt appears in the display.
2. Release the buttons and the meter will continue with a normal startup.
3. Default values include: Calibration values, Conductivity mode, ºC, MTC, APO and RENEW off
