TEMPERATURE COMPENSATION

Three options of compensating temperature are available:

Automatic (Atc): The probe has a built-in temperature sensor; the

value of the temperature is used to automatically compensate the EC/

TDS reading using 25C as reference temperature. This is the default

option.

Manual (Mtc): The temperature value, shown on the lower LCD, can

be manually set with the arrow keys. The compensation is referenced

at 25C. The "C" symbol blinks when this option is active.

No Compensation (notc): The temperature value shown on the lower

LCD is not taken into account. The reading displayed on the upper LCD

is the actual EC or TDS value. The "C" and "%TC" symbols blink when

this option is active.

To select the desired option press the ATC key until

the option is briefly displayed on the LCD.

Note: The default compensation mode is ATC.

If temperature compensation is active, measurements are compen-

sated using a default temperature coefficient of 1.90 %/C.

It is possible to select a different temperature coefficient (TC) in the

0.00 to 6.00 %/C range. To change the TC factor enter the setup

mode and select the "tc" item (see SETUP for details).

The current temperature coefficient can be

quickly viewed pressing ALT+TC. The value

is briefly displayed on the lower LCD.

The EC and TDS scales are autoranging. The meter automatically sets

the scale with the highest possible resolution.

By pressing ALT+FIXED, the autoranging

feature is disabled and the current range

is frozen on the LCD. "F1" symbol blinks

on the LCD.

To restore the autoranging option press ALT+FIXED again.

Note: Autoranging is automatically restored if the range is changed, if

the setup or calibration modes are entered and if the meter is

turned off and back on again.
