c) Parfocality
The parfocality function is activated or deactivated
by means of the
ON
and
OFF
buttons.
The parfocality can be configured via the
Adjustment
button. On pressing this button, a
wizard appears guiding you through the
configuration procedure.
All objectives must be focused successively. Start
with all dry objectives from the highest to the
lowest magnification. Then, proceed with all
immersion objectives from the highest to the
lowest magnification. By pressing the
Next
Objective
button, the nosepiece rotates to the
next objective. After all objectives were focused,
press the
End
button.
If no TFT is installed (Axio Imager M2p), parfocality may also be adjusted manually. For this to
be possible, the objective must have been successfully configured with the aid of the MTB
2004 configuration program. Carry out the following steps to this end:
•
Activate the programming mode by keeping the
LM Set
button depressed for a while (> 3 s
– acknowledgment by a long drawn-out dual beep tone). While the programming mode is
active, every second LED on the LED bar graph will be lit up. To start parfocality adjustment,
press the
RL
button on the light control.
•
Swivel in the reference objective. This is usually the objective with the highest magnification
and with air immersion. When it comes to a coded nosepiece, the position to be moved to
will be displayed through the bar graph LED. If a motorized objective nosepiece is used
though, this objective is swiveled in automatically.
•
Focus on your sample and then press one of the buttons located in the middle of the
pushbutton ring on the stand.
•
Change to the next magnification displayed. This will happen automatically if a motorized
nosepiece is used.
•
Repeat steps 3 and 4 until all the objectives have been adjusted. A tone will be sounded as
acknowledgment.
•
Complete the procedure by pressing the LM Set button again. (Acknowledgment by a single
long drawn-out beep tone. Bar graph LED returns to standard display.)
