Ion Balance Manual Adjustment Mode
In this mode, you can adjust the zero point, the point for reference for the I.C.C. function.
Ion Balance Adjustment Function
The SJ-M Series automatically senses the charged level of the target body by the I.C.C. function to
automatically control the generated amount (balance) of plus and minus ions.
The zero point, the point for reference for the I.C.C. function, is adjusted before the SJ-M Series is
shipped from the factory. However, in some environments, the zero point sometimes drifts. If this
reference zero point drifts, adequate static elimination cannot be maintained. For this reason, you need
to adjust the zero point again by “Ion Balance Adjustment Function”.
Do not turn the power OFF while the ion balance is being adjusted (about 1
minute).
■ Setting the ion balance
1
Hold down for at least one second to enter the ion
balance manual adjustment mode.
The ion balance indicator blinks.
2
Set the ion balance using .
The LED on the ion monitor corresponding to the set value lights.

Key Shifts the zero point in the – direction.
Hold down for at
least 1 second.
