1.3 Fitting the Options
Due to its variety of options, the SMIQ offers the possibility of providing the instrument with the
equipment exactly corresponding to the application. Newly fitted options are automatically recognized
and the relevant parameters added in the menu.
After every change of the instrument configuration, the CMOS RAM has to be cleared as the storage
data shift:
½ Switch off the instrument
½ Switch the instrument on again with the [RESET] key pressed
The internal calibration routines VECTOR MOD, VCO SUM, and LEV PRESET now have to be called
up again to restore the cleared calibration values.
These routines are accessible via menu UTILITIES-CALIB (see also Chapter 2, section "calibration").
The calibration routines have to be carried out in the following order:
1. VCO SUM (Summing loop)
2. VECTOR MOD
3. LEV PRESET
1.3.1 Opening the Casing
Caution:
Prior to opening the SMIQ, unplug the power connector.
Remove paneling ½ Remove four screws in the two tilt feet at the rear of the instrument.
½ Remove the upper paneling towards the top and rear.
½ Turn the instrument.
½ Remove the lower paneling towards the top and rear.
Open ventilation ducts
When an option is fitted at a slot which has not been used up to now,
the appropriate ventilation duct of the plexiglas plate at the left in the
casing frame must be opened. The openings are pre-punched so that
the respective part is easy to break out.
