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.

Figure 4-1 shows the terminal block arrangement and terminal designations for the transmitter.
NOTE: All terminals are suitable for single wires up to 14 AWG (2.5 mm2).
Wiring Tip! To comply with European Community (CE) electromagnetic
compatibility requirements, follow these general wiring guidelines:
1. Locate transmitter as far as possible from motors and other non-CE certified devices
with excessive electromagnetic emissions.
2. Use specified ferrites and cables. Failure to do so may eliminate compliance. Locate all
ferrites as close as possible to the transmitter.
•DC Power Supply Cable: Connect cable shield to earth ground at the supply end. Loop
cable 2-1/2 times through ferrite (Steward #28B0686-200, Fair-Rite Corp. #2643665702
or equivalent).
•Sensor Cable: Keep cable shields as short as possible. At the transmitter end, connect
the outer shield to earth ground, and the inner shield to the SHIELD terminal. Clamp
ferrite (Steward #28A2025-OAO, Fair-Rite Corp. #0431164281, or equiv-alent) on
sensor cable.
•Analog mA Output Cable (four-wire hookup only): Connect cable shield to earth ground
at the supply end. Loop cable 2-1/2 times through ferrite (Steward #28B0686-200, Fair-
Rite Corp. #2643665702, or equivalent).

4.1 HC1 Series Electrodeless Conductivity Sensor Wiring
Depending on how transmitter is mounted, route the sensor (or interconnect) cable into the
transmitter as follows:
• Wall/Pipe-mounted Transmitter: Route cable through left side cable entry knockout hole
in the back cover.
• Panel-mounted Transmitter: Route cable behind panel to the exposed TB2 terminal
strip.
• Integral Sensor-mounted Transmitter: Route cable through a 1/2” NPT female close
coupler and then through the swivel ball knockout hole and center hole in back cover.
(Do not open left side cable entry knockout hole in back cover.)
Wiring Tip! Route the sensor cable in 1/2-inch, grounded metal conduit to
protect it from moisture, electrical noise, and mechanical damage.
For installations where the distance between sensor and transmitter exceeds
the sensor cable length, indirectly connect the sensor to the transmitter using a
junction box and interconnect cable.
NOTE: Do not route the sensor cable in any conduit containing AC or DC power wiring
(“electrical noise” may interfere with the sensor signal). Also, always re-calibrate the
system when the cable length between sensor and transmitter changes.
Refer to Figure 4-2 and connect the sensor (or interconnect) cable wires as shown, matching
colors as indicated. (Terminal 6 is unused.)
NOTE: For systems not requiring CE compliance and lacking an earth ground, connect the
outer shield to Terminal 3 on TB2.

The MEASURE screen is normally displayed. Pressing the MENU key temporarily replaces the
MEASURE screen with the top-level “MAIN MENU CALIBRATE” branch selection screen.
Using the keypad, you can then display other screens to calibrate, configure or test the
transmitter. If the keypad is not used within 30 minutes, except during calibration or while
using specific transmitter test/ maintenance functions, the display will automatically
return to the MEASURE screen. To display the measure screen at any time, press the MENU
key once and then press the ESC key once.
The MEASURE screen can show four different readout versions. To select between them, in
continuous loop sequence, press the ÕÕ
ÕÕ
Õ or ÖÖ
ÖÖ
Ö key. These are examples of the different
versions:

When set to measure concentration, the transmitter can also show an uncompensated
conductivity reading corresponding to the measured concentration, as illustrated by this
example:
NOTE: When the transmitter returns to its normal MEASURE screen mode, the appearing
readout is always the version last selected.
Note that three MEASURE screen readout examples show the factory-default “cond”
notation on their top lines, illustrating the transmitter notation feature. To create your
own notation, refer to Section 7.2, subheading “ENTER NOTE (top line of MEASURE
screen).”
When the measured value is beyond the transmitter measuring range, a series of “ + “ or “ - “
screen symbols appear, respectively indicating that the value is above or below range.
