Device A IS powered when relay 2 is de-energized (front panel
LED "off"). Power is discontinued when the relay 2 setpoint is
reached (front panel LED "on"). Device B IS NOT powered when
the relay 2 is de-energized. Power is applied after the relay 2
setpoint is reached.
Technical Notes:
• Maximum relay contact ratings: 5 A @ 30 VDC, 5 A @ 125 VAC,
or 3 A @ 250 VAC
• An external heavy-duty relay must be used for devices with
surge currents or operating currents that exceed the above
specifi cations.
5. Relay Operation
A. LOW alarm mode
The relay is energized when the solution conductivity (mS) drops
below the setpoint, and is de-energized when the solution conductivity
rises above the setpoint plus hysteresis
(sec. 6.2F, 6.2G).
B. HIGH alarm mode
The relay is energized when the solution conductivity (mS) rises above
the setpoint and is de-engergized when the solution conductivity
falls below the setpoint plus hysteresis
(sec. 6.2F, 6.2G).
S
Low setpoint=
Adjustable hysteresis=
Relay energized=
Relay de-energized=
C. Proportional PULSE mode
The proportional pulse relay configuration is primarily designed for metering pump control. The operator is prompted to enter a minimum and
maximum conductivity setpoint and maximum pulse rate for the assigned relay (sec. 6.2H, 6.2I). Relay pulse width is fixed at 130 ms. Refer to the
operation examples below.

S
300 pulses
Example 1 (right):
As the process conductivity (S) rises above the minimum pulse setpoint (10 S) the
relay begins pulsing; triggering the metering pump for deionized water addition.
As the process conductivity continues to rise, pulsing accelerates proportionally until
the maximum programmed pulse rate of 300 pulses/minute and setpoint (90 S)
are reached, forcing the process conductivity back down to intended
levels (e.g. 10 S).
Example 2 (right):
As the process conductivity falls below the minimum pulse setpoint (90 S) the relay
begins pulsing; triggering the metering pump for chemical addition. As the process
conductivity continues to decrease, pulsing accelerates proportionally until the
maximum programmed pulse rate of 300 pulses/minute and setpoint (10 S) are
reached, forcing the process conductivity back up to intended levels (e.g. 90 S).

6.3 WET CAL Procedure
Requirements
Electronic calibration is performed to exacting standards by Signet. System calibration will reduce errors which may be caused by sensor wire lengths longer than the standard fi fteen feet length. Wire lengths of 100 feet are acceptable; cable shield must be maintained
through cable splice. Calibration may be done by known solution value (A), or by resistance simulation (B).
A) Calibration with NIST Traceable Solutions:
When using calibration standards traceable to the National Institute of Standards and Technology (NIST), care must be taken to ensure
the sensor and test solution are at the solution temperature specifi ed on the test solution label. Care must be taken to prevent contamination of the calibration solution. It is recommended to thoroughly rinse the sensor in a small amount of test solution (then discard)
before placing in any test solution for calibration purposes. The two step WET CAL process fi rst allows for verifi cation or calibration of
temperature, followed by verifi cation or calibration of either conductivity, resistivity, or PPM (TDS) using a known process solution.
B) Optional Verifi cation with Precision Resistors:
The use of precision resistors (±0.1%) connected to the rear "Temp In", "Signal IN", and "Iso Gnd" terminals in place of the
+GF+
SIGNET
sensor, will yield quick and accurate electronic instrument calibration. The WET CAL procedure allows for verifi cation or calibration of
temperature, followed by conductivity, resistivity, or PPM (TDS) utilizing precision resistors. Calibration is completed as follows:
1) Select a standard cell constant based on desired range of operation (sec. 10, Fig. 1).
2) Place a 1096Ω TC resistor between "Temp IN" and "Iso. Gnd" terminals as shown. Note: Temperature
Simulation
resistor
TC
resistor
simulation errors can adversely effect calibration: 3.85 ohms = 1°C error.
3) Calculate the required simulation resistor that represents a value within the selected cell range
(sec. 10, Fig. 1). The formula for determining the required simulation resistance is:
Resistance = Cell ; e.g. 0.1 = 5,000 or 5 k
Desired conductivity (Siemens*) 0.000020 (Siemens*)
*Conversion: 1 S = 1 X 10
Conductivity = Sensor cell ; e.g. 0.1 = 0.000001 Siemens*

7. Parts Per Million (PPM) Factor
This feature is only applicable when PPM display units are selected (sec. 6.2B).
The 5800CR is capable of displaying total dissolved solids (TDS)
in parts per million (PPM) units. This is done by dividing the actual
solution conductivity in µS by the programmed parts per million
factor (sec. 6.2C).
G. Sets 20 mA current output: 19 to 21 mA

TDS (PPM) = Solution conductivity (µS)
PPM Factor
Example:
• PPM Factor = 2.00 (factory default)
• Solution conductivity = 400 µS
• TDS (PPM) = 400 µS = 200 PPM on the display
2.00 PPM Factor
6 Signet 5800CR Conductivity/Resistivity Monitor
Page 7
The programmable PPM Factor is adjustable from 0.01 to 9.99
(factory default = 2.00). You can determine the best PPM Factor
for your process solution if you know the solution's conductivity
(µS) and the
percent of total dissolved solids (PPM), see example below:
PPM Factor = Solution conductivity (µS)
Total dissolved solids (PPM)
8. Temperature Coeffi cient (Temp. Comp. %)
Conductivity measurement is highly dependent on temperature.
Temperature dependence is usually expressed as the relative
change per °C, commonly known as percent/°C change from 25
°C, or slope of the solution.
Example:
• Solution conductivity = 400 µS
• TDS = 200 PPM (mg/L)
• PPM Factor = 400 µS = 2.00
200 PPM
3. Cool the sample solution close to the minimum process temperature. Place sensor in the sample solution (allow several minutes
for stabilization). Record displayed temperature and conductivity
values in the spaces provided below:
Slopes can very signifi cantly depending on process solution type.
The factory default temperature compensation factor is 2.00%/°C.
This setting satisfi es many general applications. Your process
solution may require adjustment for maximum accuracy. The following procedure can be used to determine the optimum temperature compensation factor for your process. This procedure can be
used when published references are not available.
Do not use this procedure for solutions from 0.055 µS to 0.1
µS (10 MΩ to 18 MΩ). An internal pure water curve is used for
these ranges. The factory default setting of 2.00%/°C should
be used.
Equipment Required
• 5800CR monitor and 28XX-1 series conductivity sensor
• Process solution samples (2)
• Temperature source
Procedure
1. Disable the 5800CR's temperature comp % factor by entering
0.00 (sec. 6.4I).
2. Heat the sample solution close to the maximum process
temperature. Place sensor in the sample solution (allow several
minutes for stabilization). Access the VIEW menu (sec. 6.1A) and
record the displayed temperature and conductivity values in the
spaces provided below:
Sample Solution (Step 3)
Displayed temperature:
T2= °C
Displayed conductivity:
C2= µS
A 10% change in conductivity between steps 2 and 3 is required
for optimum performance. If necessary, increase maximum (step
2) and reduce minimum (step 3) sample temperatures. This will
result in a larger change in conductivity between steps.
4. Substitute recorded readings (steps 2 and 3) into the following
formula:
TC Slope = 100 x (C1 - C2)
(C2 x (T1 - 25))
- (C1 x (T2 - 25))
Example:
A sample solution has a conductivity of 205 µS @ 48°C. After
cooling the solution, the conductivity was measured at 150 µS @
23 °C. Therefore: C1 = 205, T1 = 48, C2 = 150, T2 = 23.
The TC is calculated as follows:
Sample Solution (Step 2)
Displayed temperature:
T1= °C
Displayed conductivity:
C1= µS
TC Slope =
100 x (205 - 150) = 5500 = 1.42%/°C

Press any Key
Temperature wiring shorted or temperature element in sensor bad
A) Sensor not connected or improperly
connected
B) Pipe empty or sensor not in solution
C) Wrong scale selected
D) Wrong range selected (cell constant
too small)
E) TC% set incorrectly for process temperature
F) Sesnor wiring open
G) Water too cold for high-purity water
measurement
A) Sensor shorted or improperly connected
B) Wrong scale selected
C) Wrong range selected (cell constant
too large)
D) TC% set incorrectly for process temperature
Temperature input out of tolerance during
WET CAL Procedure (sec. 6.3)
Zero entered as solution conductance or
resistance during WET CAL step 2
Power fault occured while saving setup

A) Verify sensor wiring (sec. 2)
B) Verify instrument temperture input:
Remove Black and White sensor wires from rear Temp. IN and Iso. Gnd
•
terminals, then place a 1100 Ω resistor across terminals.
Power instrument and verify approximately 26.0°C (79°F) on display.
•
If instrument reads correctly, replace sensor. If error condition persists,
instrument requires factory service.
A) Verify sensor wiring (sec. 2)
B) Fill pipe or place sensor in process solution.
C) Choose μS or MΩ scale instead of mS or kΩ scale (sec. 6.2B)
D) Choose a sensor with cell constant adequate for your process solution (sec.
10, Figure 1)
E) Set TC% to zero (sec. 6.41) and check reading. If reading is ok, calculate
proper TC% for your process solution (sec. 8), then re-enter correct value (sec.
6.41).
F) Replace sensor
G) See specifi cations section 10 for recommended high-purity range and temperature requirements.
A) Verify sensor wiring including cable splice (sec. 2); cable shield must continue through splice.
B) Choose mS or kΩ scale instead of µS or MΩ scale (sec. 6.2B)
C) Choose a sensor with cell constant adequate for your process solution, see
section 10, Figure 1.
D) Set TC% to zero (sec. 6.41) and check reading. If reading is ok, calculate
proper TC% for your process solution (sec. 8), then re-enter correct value (sec.
6.41).
Exit WET CAL Procedure by pressing UP and DOWN arrow keys simultaneously, then refer to solution steps 1B above to verify sensor temperature input.
Measured conductivity, Resistvity, PPM, or resistivity entered as zero to quickly
recall factory defaults.
Press any key to reload factory defaults then reporgram conductivity system
setup parameters.
