1.6 Display
Stage height
When an upper threshold is set, the height of the
stage in relation to the upper threshold is
indicated in the display, e.g. "-012".
The unit is displayed automatically with the two
LEDs µm and mm (i.e. 12 µm or 12 mm below the
upper threshold). Positive values signify stage
positions above the upper threshold.
If the upper threshold is not set, you will see
"Set?" in the display. If the lower threshold is
not set, the downwards arrow ↓ will not be
displayed.
Magnification display
Regardless of the threshold status, you can
switch between a display of the stage height
and a display of the objective magnification (see
page 64) by simultaneously pressing the keys
"Upper threshold" and "Lower threshold" (44.5
and 44.6).
Switching over the display influences neither
the thresholds nor the stage height.
1.7 Collision and overload protection
!
Attention:
If the electronics register overload or a collision
while the motor focus is being operated with
"Up" or "Down", the motor is actively braked
and switched off, and the display flashes.
In this case the stage should be immediately
moved clear in the opposite direction.
We cannot accept any liability for damage due
to operation errors.
1.8 Leica DM RXE microscope only:
Lamp voltage setting
With the exception of the Leica DM RXE
microscope the lamp voltage is adjusted directly
with the dial (48.24).
On the Leica DM RXE microscope, the dial
(48.24), which acts as a switch, must be slightly
turned clockwise until the voltage value of the
lamp (5 – 12 V) appears in the display (44.7); the
lamp voltage can be controlled with the
focusing wheel (44.4), if this position is
sustained.
When the switch is in the home position the
handwheel takes over the z drive control again.
This setting allows interactive adjustment of the
lamp voltage when a PC is connected. See
separate instructions for further details.
