8.3 Asymmetry Buffer calibration
8.3.1 Single-point calibration:
In single-point calibration, it is only necessary to
calibrate OS value and the unmodified SLP value. The
instrument will apply the factory defaults or the SLP
value of last calibration.
1. When entering CA1 calibration mode, clean the
electrode with distill water before putting it in the buffer
solution. Press to start the calibration. Then display
will show the mV value of the buffer and begin to
twinkle. After showing a similar number of pH value to
the buffer solution, push or to set the digit
until it is equal to the buffer’s standard. Then, push
to ensure it.
2. When the display shows “CA2”, push and the
display will show OS value. Push to back to the
measurement mode.
8.3.2 Dual-point Calibration
1. When entering CA1 calibration mode, clean the
electrode with distill water before putting it in the buffer
solution. Press to start the calibration. Then display
will show the mV value of the buffer and begin to
twinkle. After showing a similar number of pH value to the
buffer solution, push or to set the digit until it
is equal to the buffer’s standard. Then, push to ensure
it.
