Meter Setup
The BI-650 meter contains an integrated setup menu for customizing
the displayed option to meet measurement requirement. The following
table describes the functions of each menu item.
Menu Item
Option and Description
Cell Constant
Set the cell constant to match connected conductivity
electrode.
K = 0.1, 1, 10 (default 1)
Calibration Points
Set the number of calibration points.
1 to 3 points (default 1 point)
Temperature Coefficient
Set the temperature coefficient for linear temperature
compensation.
0.0 to 10.0%/° C (default 2.1)
TDS Factor
Set the default TDS conversion factor.
0.1 to 1.0 (default 0.5)
Temperature Unit
Degrees Celsius (default)
Degrees Fahrenheit
Low Alarm Limit
Setting range: 0.02 µ S/cm to 20.00 mS/cm
(default 0.02 µ S/cm)
High Alarm Limit
Setting range: 20.00 mS/cm to 0.02 µ S/cm
(default 1000 µ S/cm)
Hysteresis Value (Low)
Setting range: 1% to 99% (default 10%)
Hysteresis Value (High)
Setting range: 1% to 99% (default 1%)
Analog Output (Low)
Setting range: 0.02 µ S/cm to 20.00 mS/cm
(default 0.02 µ S/cm)
Analog Output (High)
Setting range: 20.00 mS/cm to 0.02 µ S/cm
(default 20.00 mS/cm)
Factory Reset
Reset the meter to factory default settings. Note,
the meter must be recalibrated.
Enable
Disable (default)
•
If the high or low alarm is enabled, the meter will be activated
when the measurement exceeds specified limit. Note, this option
can not enter the same values.
•
If the hysteresis is enabled, the meter will prevent rapid contact
switching when the measurement is fluctuating near the set
point. For example, you have set the high alarm at 20 mS/cm
and hysteresis value at 1%. When the measurement overshoots
the 20.2 mS/cm, the meter will activate an external device. When
the measurement drops to 19.8 mS/cm, the device will switch off.
•
The default RS485 communication is 0.02 µ S/cm to 20.00 mS/cm
corresponds to the 4.00 to 20.00 mA.
