EC/TDS
Measurements
No Temperature Compensation (No TC)
: The temperature value is displayed,
but not taken into account. When this option is selected, the “NoTC” tag will
be displayed. The reading displayed on the primary LCD is the uncompensated
EC or TDS value.
Note
:
•
The default compensation mode is ATC
•
The compensation is referenced to the selected reference temperature
(see SETUP for details).
If temperature compensation is selected, measurements are compensated
using the temperature coefficient (default value 1.90 %/ºC, is recommended
for natural water samples).
To change the temperature coefficient, enter the SETUP mode and select
“T.COEF.(%/ºC)” (see SETUP).
The current temperature coefficient can be viewed on the 3rd LCD line by
pressing the ARROW keys until it is displayed. The value is displayed along
with Cell Factor. If the temperature reading is out of range, the closest full
scale value will be displayed with “ºC” blinking on the 2nd LCD line.
If the temperature reading is out of probe specification range, the value
is displayed blinking along with “PROBE OUT OF SPEC” message. If the
temperature sensor is broken, the message “BROKEN TEMPERATURE
SENSOR” and “----” is displayed along with the unit tag blinking on the 2nd
LCD line.
TDS Measurements
Press the RANGE key. The instrument will switch to TDS measuring range. The
TDS reading will be displayed on the 1st LCD line and
the temperature reading on the 2nd LCD line. If the
reading is out of range, the full-scale value (100.0
g/L for ATC mode or 400.0 g/L for uncompensated
TDS) will be displayed blinking.
