CALIBRATION
Enter calibration mode
At measurement mode, Keep press the middle button 3 seconds to enter the calibration
mode.
The main display shows the current calibration point at 1413uS/cm.
The second display shows the current measure reading (last 3digital). CAL symbol is flashing.
Use the standard solution
Prepare standard solution (1413uS/cm) for calibration. Store the standard solution in the
25degCenvironment.
Calibration step:
Step1: Place the probe in the standard solution. After about 30sec of stabilization, Press the
middle button to save the data, then keep press the left button to power off.
Advanced setting
:
(Temperature calibration/ Conductivity transfer at the preset for TDS and
Salt / ATC parameter preset)
If you are using advanced application, then you can present the
Conductivity transfer rate for
TDS and salt
. And if you have temperature adjust or temperature compensation parameter
adjust. Please use following process:
Enter Advance setting mode
: Keep press middle button when power off device, press once
left button to turn on device, after 2sec release middle button.
Step 1:
Make temperature calibration. Temperature reading, and ATC symbol is show at
second display area, with flashing CAL symbol. Press left button to decrease/Press right button
to increase the current temperature reading. Press middle button once to save the data and
go to next step.
Step 2:
Conductivity transfer rate setting for TDS. The parameter shows at main display area,
default 0.500
. It is meaning “TDS reading = Conductivity reading x Transfer rate”. Press left
