Conductivity/Resistivity Analyzer/Controller
9782 Series Conductivity/Resistivity Analyzer/Controller - Operator’s Manual 7/992-4
Performance under reference operating conditions
Display Accuracy:
Standard Ranges (Conductivity/Resistivity); ±0.5% of reading.
Wide Ranges (Conductivity); ±0.5% of reading or 0.02% of span.
Concentration; ±0.5% of span, ±1% conformity to conductivity vs. concentration data tables.
Output accuracy: Adjustable to within 0.01 mA, repeatable to within ±0.1% of span.
Reference Operating Conditions: 25 ±1 °C; 10 to 40% RH; 120 or 240 Vac; process temp 25 °C
measured
Operating Influences under normal operating conditions
Effect on accuracy (
%
of span): Temperature: 0.05% per °C; RH: <1%; Line Voltage: <0.1%
per volt; Power Loss: memory retention by EEPROM (no batteries).
2.1.7 Outputs
Standard alarm/control relays
Two SPDT Form C general purpose relays rated 0.6 amps at 120/240 Vac, 0.6 amps at 110 Vdc,
2 amps at 30 Vdc. Maximum switching power for ac, 125 VA resistive; for dc, 60W resistive.
Optional alarm/control relays
9782C- _ _ - R2: Two additional SPDT Form C, rated at 3 amps at 120 Vac
or 28 Vdc, no analog outputs
9782C- _ _ - R0: Two hermetically sealed Form C, rated at 3amps at 120 Vac
or 28 Vdc, plus one analog output 0 to 1 Vdc or 0 to 10 Vdc
or isolated 4 to 20 mA.
Optional analog outputs
One, two or three 4 to 20 mA outputs are available via an optional plug-in circuit card and
program module. Isolated from ground, inputs and one another.
Maximum isolation voltage: 240 Vac (will withstand 1500V hi-pot test).
Output adjustment: to within 0.01 mA.
Repeatability: ±0.1% of span. 600 ohm maximum load resistance. Proportional to selected
output
range.
9782C- _ _ - 00: None
9782C- _ _ -VC: One analog output: 0 to1V or 0 to10 Vdc or isolated 4 to20
mA dc (600 ohms maximum load)
9782C- _ _ - C2: Two analog outputs: both isolated 4 to 20 mA dc.
9782C- _ _ - C3: Three analog outputs: all 4 to 20 mA dc
One analog output also available in combination with optional relays (see above).
