3. Adjusting ion balance
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 can
adjust the SJ-M Series to the desired zero point.
In Ion Balance Adjustment mode, you can adjust the zero point, the point for reference for the I.C.C.
function.
Do not turn the power OFF while the ion balance is being adjusted (while the
ion balance indicator is blinking fast).
■ Ion balance adjustment overview
The unit starts up in the Run mode after the power is turned ON or after static elimination is
stopped.

Tip
1
Hold down for at least one second to enter the
Ion Balance Adjustment mode.
The ion balance indicator blinks.

value lights up.
Key Function

direction.
Shifts the zero point in the -
direction.
Hold down for at
least 1 second.
3-1 SJ-M Series Operations
Holding down for about 1
second when setting the ion
balance clears the preset ion
balance zero point and returns the
ion balance to its default setting.
3
Press to end ion balance setup.
The mode changes to the Run mode.
After the setting, the ion balance indicator will blink fast for up to 3 min,
indicating that the settings are being saved in the memory.
After you have finished setting up the ion balance,
do not change the ambient environment while the
ion balance indicator is blinking fast. If you do, the
zero point sometimes cannot be set accurately.
Note
Blink fast

During this operation,
the ion monitor indicatio
