Power Requirements (Class 2 Power Supply):
Two-wire Hookup 16-30 VDC
Three-wire Hookup 14-30 VDC
Four-wire Hookup 12-30 VDC
Calibration Methods:
Sensor Zero With the dry sensor in air, press keys to initiate
(all measurements) 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)
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.
Concentration Measurement:
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
TDS Measurement:
TDS CAL Enter one sample value (determined by laboratory analysis
or a comparison reading)
Analog Output Isolated 4-20 mA output with 0.004 mA (12-bit) resolution
NOTE: The output can be assigned to represent the measured value (conductivity, %
concentration or TDS) or measured temperature. Parameter values can be entered to
define the endpoints at which the 4 mA and 20 mA output values are desired (range
expand). During calibration, the output is automatically held at the last measured
value and, upon completion, returned to its active state.
Maximum Loop Load Dependent on power supply voltage, transmitter hookup
arrangement, and wire resistance (see load resistance
charts for respective hookup diagrams in Section 4.2, 4.3 or
4 .4)
Memory (non-volatile) All user settings are retained indefinitely without battery
backup
Electrical Certifications UL, C-UL Pending
