Step 4: Calibrate the E.C. Circuit for low side μs/cm readings
Now that the E.C. Circuit has been calibrated for the high side, now calibrate
it to the low side.
The second calibration event is done on the low side.
Do not do low side calibration first.
K0.1 Second calibration: 220μs/cm
K1.0 Second calibration: 10,500μs/cm
K10.0 Second calibration: 62,000μs/cm
• Place the E.C. Sensor in the low side calibration solution.
• Put your E.C. Circuit in continues mode by transmitting the “C” command.
• Let the E.C. Circuit run in continues mode for 3-5 minutes. The readings will
start to stabilize after 3-5 minutes.
• Transmit low side calibration command
Sensor type Low side calibration solution Low side calibration command
K 0.1 220μs/cm Z2
K 1.0 10,500μs/cm Z10
K 10 62,000μs/cm/cm Z62
Example:
(Here we calibrate an E.C. Circuit connected to a K10 Sensor.)
Full proper syntax: z62 or Z62
The E.C. Circuit will respond: 62,000 μs/cm cal
