2.2 Transmitter Performance
(Electrical, Analog Outputs)
2.3 Mechanical
Concentration Measurement:
CONC CAL ...................... Enter one sample value (determined by labo-
ratory analysis or a comparison reading)
COND CAL ...................... Enter compensation reference temperature,
linear % per °C slope, and one known refer-
ence solution value
TDS Measurement:
TDS CAL ......................... Enter one sample value (determined by labo-
ratory 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 selected measurement
(conductivity, % concentration or TDS) or 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 PART TWO,
Section 3.2, 3.3 or 3.4)
Memory (non-volatile)................. All user settings are retained indefinitely with-
out battery backup
EMI/RFI Conformance................ Exceeds US and meets European standards
for conducted and radiated emissions and
immunity; certified CE compliant for applica-
tions as specified by EN 50081-2 for
emissions and EN 50082-2 for immunity
Electrical Certifications:
General Purpose (pending) ..... UL, C-UL, FM, and CENELEC
Class 1, Div. 2 (pending)......... UL, C-UL, and FM: Groups A, B, C, D, F, and G
Accuracy*................................... ± 0.1% of span
Sensitivity* ................................. ± 0.05% of span
Repeatability*............................. ± 0.05% of span
Temperature Drift*...................... Zero and Span: ± 0.02% of span per °C
Response Time .......................... 1-60 seconds to 90% of value upon step
change (with sensor filter setting of zero)
*These typical performance specifications are:
1. Based on 25°C with conductivity of 500 µS/cm and higher. Consult
GLI for applications in which conductivities are less than 500 µS/cm.
2. Derated above 100°C to the maximum displayed temperature of
200°C. Consult GLI for details.
Enclosure................................... Polycarbonate; NEMA 4X general purpose;
choice of included mounting hardware
