Note: The compensation is referenced at the selected reference temperature (see
SETUP for details, page 26).
Automatic (ATC)
: The EC probe has a built-in temperature sensor; the temperature value is
used to automatically compensate the EC/TDS reading (from -20.0 – 120.0 °C).
Manual (MTC)
: The temperature value, shown on the secondary LCD, can be manually set
with the UP and DOWN arrow keys. The “°C” tag blinks when this option is active.
No Compensation (NOTC)
: The temperature value is displayed, but is not taken into
account and “°C” tag blinks. The reading displayed on the primary LCD is the uncompen-
sated EC or TDS value. To select the desired option, press the SHIFT&
/ATC keys until
the option is displayed on the LCD.

Notes:
•The default compensation mode is
ATC
.
• If no temperature probe is detected,
ATC
mode can not be selected and the instru-
ment displays “----” on the secondary LCD.
If temperature compensation is active, measurements are compensated using the tem-
perature coefficient (default value 1.90 %/°C). To change the temperature coefficient,
enter the setup mode and select the “tc” item (see SETUP for details, page 26). The
current temperature coefficient can be quickly viewed by pressing the SHIFT&
/TC keys.
The value is briefly displayed on the secondary LCD.
• If the temperature reading is out of the -20.0 to 120.0 °C (-4.0 to 248.0 °F) interval and
ATC
option is selected, the “°C” tag will blink and the closest interval limit will be displayed.
• Press the UP and DOWN arrow keys to change the displayed temperature value. This
value is used to compensate the EC/TDS reading.
