MW170 Bench Meter
Readings can be temperature compensated.
y
Automatic Temperature Compensation (ATC) default:
The probe has a built-in
temperature sensor; the temperature value is used to automatically compensate the
EC / TDS reading.
When in ATC mode, ATC tag is displayed and measurements are compensated
using the temperature coefficient. Recommended default value for water samples
is 1.90% / °C. Temperature compensation is referenced to the selected reference
temperature.
Use the
keys to view the current temperature coefficient. The value is displayed
along with Cell Factor (C.F.) on the third LCD line.
To change the temperature coefficient, see EC Temperature Coefficient (T.Coef.) in
SETUP OPTIONS section.
A temperature coefficient must also be set for the sample.
Note: If the reading is outside range when the range is set to automatic, the full-scale
value (200.0 mS/cm for MTC/ATC or 500.0 mS/cm for NO TC) is displayed blinking.
y
Manual (MTC):
The temperature value, displayed on the second LCD line, can be
manually set using the
keys. When in MTC mode, the °C tag is displayed
blinking. In MTC mode, values cannot be set outside range values.
y
No Temperature Compensation (NO TC):
The temperature value is displayed, but
not taken into account. With option selected, the NO TC tag is displayed. The reading
displayed on the first LCD line is the uncompensated EC or TDS value.
Note: Temperature compensation and absolute conductivity (NO TC) are configured in
Setup.
TDS Measurement
Press RANGE/
to select TDS range.
y
The TDS reading is displayed on the first LCD line and the temperature reading on
the second LCD line.
y
Measured value is displayed in the set parameter unit (ppm or mg/L).
See TDS Unit in SETUP OPTIONS section.
