Standby/Zero Function:
The AIC3Pro Air Ion Counter
comes factory calibrated (gain
and zero-point established) and
ready to use. If some time has
passed, temperature has
changed, or if an offset greater
than .05 is present, re-zero may
be requred. The Standby/Zero
button allows access to this
zeroing process (the zero settings menu also provides
access to this screen). Offsets may be removed manually
by pressing the up or down arrow buttons, and auto-
matically by pressing 'Reset Peak'. Because the unit is
sensitive during manual and automatic zero, place the
AIC3 on a stable surface away from materials that may
hold a static charge such as plastics and away from any
ion sources like air ionizers when zeroing the meter. (See
'Menu, Zero Settings' to see further zero options, such as
setting an automatic zero interval for long-term
measurements).
