"THREE ARROW" button for carousel up and down movement
Leica TP1020
The "THREE ARROW" button is used to start and stop the carousel (tissue
basket) up and down movement.
When this function is activated, the tissue basket is lifted and lowered in
three-second intervals within the processing stations. This ensures a uni-
form mixing of all liquids and an optimized tissue infiltration.
This function is automatically activated when an automatic processing
cycle is started.
It can be switched off and back on at any time, also when no processing
cycle is running.
With the function being activated, the green diode in the "THREE ARROW"
button is lighted.
• To switch off the function, press the "THREE ARROW" button.
The diode is extinguished; the function is switched off. It can, however, be
turned back on at any time.
• To reactivate the function press the "THREE ARROW" button once again.
If the tissue basket is located in a wax bath that contains solid par-
affin, the instrument disconnects the up/down function automati-
cally.
