2.1
Operational
Display....................................... Two-line by 16 character LCD
NOTE:
The measured value (conductivity, % concentration or TDS) and tem-
perature can be displayed separately or shown together on a single
screen. The corresponding 4-20 mA analog output value can also be
shown. (When measuring concentration, the transmitter can also
show a corresponding readout of uncompensated conductivity.)
Measurement
Ranges
Conductivity .......................... μS/cm: 0-200.0 or 0-2000
mS/cm: 0-2.000, 0-20.00, 0-200.0 or 0-2000
S/cm:
0-2.000
% Concentration ................... 0-99.99% or 0-200.0%
TDS ...................................... 0-9999 ppm
Temperature ......................... -4.0 to 392.0
°
F or -20.0 to +200.0
°
C
Analog Output....................... 4.00-20.00 mA
Ambient Conditions:
Operation.............................. -4 to +140
°
F (-20 to +60
°
C); 0-95% relative
humidity, non-condensing
Storage ................................. -22 to +158
°
F (-30 to +70
°
C); 0-95% relative
humidity, non-condensing
Temperature Compensation ....... Automatic from 14.0 to 392.0
°
F (-10.0 to
+200.0
°
C) with selection for Pt 1000 ohm
RTD temperature element, or manually fixed
at a user-set temperature
NOTE:
The selected measurement (conductivity, % conc. or TDS) determines
which of the following temperature compensation methods are available:
Linear % per
°
C slope, built-in natural water temperature proper-
ties table, user-entered temperature table, or no compensation
Sensor-to-Transmitter Distance .. Maximum cable length is a function of the
measuring range and allowable non-linearity.
The following schedule is recommended:
Full-scale Range
Max. Length
200 to 2000 μS/cm ................200 ft. (61 m)
2000 to 2,000,000 μS/cm.......300 ft. (91 m)
NOTE:
When measuring % concentration, convert the transmitter full-scale
value to conductivity to determine the maximum distance.
Power Requirements (Class 2 Power Supply):
Two-wire Hookup .................. 16-30 VDC
Three-wire Hookup ................ 14-30 VDC (16 VDC min. with RS-485 comm.)
Four-wire Hookup.................. 12-30 VDC (16 VDC min. with RS-485 comm.)
Calibration Methods:
Sensor ZERO........................ With the dry sensor in air, press keys to
(all measurements)
initiate automatic system zeroing
Conductivity Measurement:
COND CAL ...................... Enter compensation reference temperature,
and reference solution’s known linear % per
°
C slope and value
SAMPLE CAL .................. Enter one sample value (determined by
laboratory analysis or a comparison
reading)
