ISE Calibration and M easurement
Please note that it is not available to calibrate just only 1 point. If try exit after
calibrating only 1 point, error message (¡ Err¡ ) is displayed. In this case press
Reset
key
or continue calibration.
Preparation
Connect meter with electrode and ATC.
Prepare a required solution for measurement and magnetic stirrer.
Set buffer(standard) solution in Setup. Refer to Setup.
Calibration should be done in order from the lower concentrated solution to the more
concentrated solution.
Calibration and Measurement
1)
Calibration of CAL1 (Buffer 1)
In ISE ready condition, press
Cal
key and then the set buffer in Setup is shown as
follows.
After rinsing electrode with distilled water and put
electrode into the first buffer.
With constant, but not violent, stirring for accurate
measurement, press
M easure
key.
Millivolt corresponding to concentration of ion is displayed.
If mV reading is stable, press
Cal
key.
The left figure indicates the end of CAL1 calibration.
