1.1 Capability Highlights
Sensor Input
The transmitter can be used with the Model HC1-Series electrodeless conductivity sensor.
These sensors have a built-in Pt 1000 RTD temperature compensator element.
MEASURE Screen
The measure screen (normal display mode) can provide different readouts of measured data.
With the MEASURE screen displayed, press ÕÕ
ÕÕ
Õor ÖÖ
ÖÖ
Ö to show:
•Measured conductivity, % concentration or TDS
•Measured temperature (°C or °F)
•Measured conductivity, % concentration or TDS and temperature
•Measured analog output value (mA)
• Uncompensated conductivity corresponding to concentration readout (only shown
when transmitter is set to measure concentration)
Password-Protected Access
For security, you can enable a passcode feature to restrict access to configuration and
calibration settings to authorized personnel only. See Section 7.5 for details.
Calibration Methods
Because each sensor has a unique zero point and span, always zero the sensor in air when
calibrating it for the first time (Section 8.2). Depending on the configured measurement
(conductivity, % concentration or TDS), different methods are available for calibrating sensor
span (see Section 8.3, 8.4 or 8.5 respectively). The analog output loop can also be calibrated
(Section 8.6).
Analog Output
The transmitter’s isolated 4-20 mA analog output can be assigned to represent one of these:
•Measured conductivity, % concentration or TDS
•Measured temperature.
Parameter values can be entered to define the endpoints at which the 4 mA and 20 mA analog
output values are desired (range expand). For analog output setup details, see Section 7.4.
NOTE: During calibration, the analog output is automatically held at the last measured value
and, upon completion, returned to its active state.

condensing

Temperature Compensation Automatic from 14.0 to 347.0°F (-10.0 to +175.0°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 properties 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.

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)
ELECTRONIC CAL This method requires that the sensor be removed from the
process and utilizes a decade resistance box to simulate
conductivity rather than an actual solution.

CONC CAL Enter one sample value (determined by laboratory analysis
or a comparison reading)
COND CAL Enter compensation reference temperature, and reference
solution’s known linear % per °C slope and value

expand). During calibration, the output is automatically held at the last measured
value and, upon completion, returned to its active state.

Unpack and examine the equipment even if you do not use it immediately. If there is evidence of
damage, notify the transit carrier immediately.
Recommendation: Save the shipping carton and packing materials in case the instrument must
be stored or re-shipped.
3.1 Location3.1 Location
3.1 Location3.1 Location
3.1 Location
1. It is recommended to locate the transmitter as close as possible to the installed sensor.
The maximum allowable distance between an installed sensor and the transmitter
depends upon the full-scale value you set for the transmitter measuring range:
200-2000 µS/cm
Full-scale Value
2000-2,000,000 µS/cm
Full-scale Value
200 feet (61 m) max. 300 feet (91 m) max.
NOTE: When measuring % concentration, convert the transmitter full-scale value to
conductivity to determine the maximum distance.
2. Mount the transmitter in a location that is:
• Clean and dry where there is little or no vibration.
• Protected from corrosive fluids.
• Within ambient temperature limits (-4 to +140°F or -20 to +60°C).
CAUTION:
EXPOSING THE TRANSMITTER TO DIRECT SUNLIGHT MAY INCREASE
THE OPERATING TEMPERATURE ABOVE ITS SPECIFIED LIMIT, AND
DECREASE DISPLAY VISIBILITY.

Figure 3-1 illustrates how to panel mount the transmitter using the supplied panel mount
hardware kit.
1. Cut a 3.30-inch (84 mm) square cutout hole in panel.
2. Position panel-mount gasket over cutout in front of panel, and place retainer plate
behind panel with its four threaded inserts facing away from back of panel.
3. Attach transmitter to retainer plate using its four captive screws.
NOTE: If panel is too thick, remove captive screws from transmitter, and use longer screws
provided in hardware kit.
