Fault removal Biometra TRIO

14.5 Mirror programs to several thermal cyclers
Using the backup function, complete thermal cyclers can be mirrored. Copy complete us-
ers (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 section 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 section 7.6.2. Alternatively, the time settings may be extended.
14.7 Release wheel in case of blocked lid
When the lid is in the highest or lowest position, it may happen that the wheel is uncou-
pled. 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 exces-
sive pressure.
Release lid in upper position:
1.
Press pin.
Carefully turn wheel while holding the pin down
CLOCKWISE, until you feel normal resistance (no
more clicking noise, clutch is released). Release pin
and turn lid down, until the clutch mechanism is ac-
tivated (clicking noise, optimum pressure applied).
Release lid in down position:
Press pin.
Carefully turn wheel while holding the pin down
COUNTER CLOCKWISE, until you feel normal re-
sistance (no more clicking noise, clutch is released).
Release pin and turn wheel counter clockwise until
pressure is completely released. Open lid.
: When the clutch mechanism is
active (= optimum pressure is applied), do not use the
pin to further increase lid pressure
. This leads to dam-
age of tubes and instrument!
