At rst the AUTOCAL IN.. menu serves as an
information menu, showing the remaining time
till the next calibration procedures are started.
The countdowns start the moment, you enter
"interval time" values in the previous menu.
The second option, this menu offers, is to

calibrations earlier than specied by the "in-

This activates ZeroAll calibrations at
9:55 p.m. and 9:55 a.m. every day
(rst calibration takes place at 9:55 p.m. the
same day)
and ZSCalAll calibrations at
9:55 a.m. every day
(rst procedure carried out the next day).
So, ZeroAll calibrations are carried out at
10:00 a.m. and 10:00 p.m. every day
(but the rst calibration now takes place at
10 a.m. the same day!)
and ZSCalAll calibrations are now activated
at 1:00 a.m. every day,
with the rst procedure to be carried out early
the next day.
To have e.g. ZeroAll calibrations take place at
10 a.m. & 10 p.m. and ZSCalAll calibrations
in the night at 1:00 a.m., open the AUTOCAL
IN.. menu and enter
Example:
Current time is: 9:55 a.m.
Interval times are setup at this time to have
all channels zeroed in a 12 h interval and all
channels zeroed & spanned in a 24 h interval:
