Mirror programs to several thermal cyclers
Using the backup function, complete thermal cyclers can be mirrored. Copy complete
users (via user management) and their programs from one thermal cycler to the other
without having to create each individual user or program. The prerequisite is that both
cyclers have the same software version (see chapter 11.7).
14.6
Adapt protocols from other cyclers
Since the Biometra TRIO is a fast instrument it may be necessary to reduce the heating
and cooling ramps to run protocols from other cyclers. For the setting of the heating
and cooling ramps see chapter 7.6.2. Alternatively, the time settings may be extended.

Release wheel in case of blocked lid
When the lid is in the highest or lowest position, it may happen that the wheel is un-
coupled. In this situation the clutch mechanism is active in both directions (clicking
noise in either direction).
To unlock wheel, press down metal pin with a ball pen and turn wheel carefully. This
pin overrides the automatic clutch mechanism. Thus, care must be taken not to apply
excessive pressure.
Release lid in upper position:
1.
Press pin.
2.
Carefully turn wheel while holding the pin
down
CLOCKWISE
, until you feel normal re-
sistance (no more clicking noise, clutch is
released). Release pin and turn lid down,
until the clutch mechanism is activated
(clicking noise, optimum pressure applied).
Release lid in down position:
1.
Press pin.
2.
Carefully turn wheel while holding the pin
down
COUNTER CLOCKWISE
, until you feel
normal resistance (no more clicking noise,
clutch is released). Release pin and turn
wheel counter clockwise until pressure is
completely released. Open lid.
Important
: When the clutch mechanism is
active (= optimum pressure is applied), do not
use the pin to further increase lid pressure.
This leads to damage of tubes and instrument!
