Limit Timer
– Set this value to the maximum amount of time the bleed output can stay
energized before a Bleed Limit alarm is reported. The limit time setting only reports the
alarm and does NOT turn off the bleed output. If the next bleed cycle completes without
an alarm the alarm will clear itself. Setting this value to 00:00 turns off this function.
Probe Calibration
– Use this function to calibrate the probe. Enter the calibrated
conductivity value that you would like the controller to display.
The conductivity probe is very sensitive to temperature changes. Allow the probe roughly 10
minutes to adjust to the temperature of the test solution or sample. Calibrating the probe without
allowing the probe to equilibrate to the sample temperature could result in erroneous controller
conductivity readings.
Only use a calibration meter that incorporates temperature compensation when performing a
probe calibration.
Alarm Setpoint
– Pick the type of conductivity alarm tracking you want to use.
Track Setpoint
– Use this type if you want an alarm when the conductivity
reaches above or below the conductivity setpoint an equal amount.
Example: Setpoint=1200, Track Setpoint=200, an alarm will be reported when
the conductivity reaches above 1400 or below 1000.
Independent Setpoint
–
Use this type if you want to specify an upper and lower
conductivity value for alarm reporting.
Example: Setpoint=1200, low=900, high=1450, an alarm will be reported when
the conductivity reaches above 1450 and below 900.
4-20 Output
– Use this option to configure how you want the 4-20ma output to
behave with respect to the conductivity reading.
Adjust Range
– Use this option to set the low and hi conductivity readings used
to scale the 4-20ma output.
Example: Low Range=500, High Range=2000, when the conductivity reading is
500 the 4-20 ma output would be 4ma, when the conductivity reading is 2000 the
4-20ma output would be 20ma.
Calibrate Output
–
Use this option to calibrate or “fine-tune” the 4-20ma output.
You can adjust both the 4ma and 20ma settings a small amount to compensate
for un-calibrated downstream meters or displays.
