6.5 Frequently Asked Questions
Question Answer
Can the print cycle time settings for the heating
and sterilisation cycles be different (e.g. 1 minute
and 5 minutes, respectively)? No, these intervals must be the same for the pro-
gram.
What happens in the event of a power failure? When the power supply is cut, the instrument
remains in the safety mode. The safety cover
cannot be opened. When power resumes, the
user has the option of continuing with the inter-
rupted program or stopping the program.
Stopping the program leads to a cooling to 80°C.
The agar must be discarded.
Continuing the program causes resumption at the
beginning of the interrupted cycle.
The MediaClave will take 30 seconds to restart.
What causes an excess of agar to remain at the
bottom of the cuvette at the end of a process
(circa 2 cm high)? The length of the internal tube connected to the
dispensing port may be too short. The length of
silicone tubing must be at least 215–218 mm.
Why does the safety cover lock become warm
during normal operation? The bolt is magnetically operated and releases
only if the cover is closed. The magnet runs when
the cover is open, and so produces heat. Thus,
this is a normal phenomenon.
What can be done when the paper does not feed
correctly from the printer? Ensure that paper is removed after each run.
What can be done when the pressure test fails? Remove rubber lid seal. Wet and replace it.
Are all the processes reported in the printout? No. For example, the transition from the sterilisa-
tion cycle to the cooling cycle takes approxi-
mately 1 minute. This process time is not
documented
What is the average consumption of cooling
water? 1.5 - 2.5 litre per minute during cooling down
sequence. It also depends on the distribution
pressure and on valve settings.
Is the PT100 GLP compatible?
Can this be calibrated independently? The MediaClave is CE marked. For GLP pur-
poses, it is possible to build in a galvanically sep-
arated double PT100.
What does the user do when STEP is pressed in
error? The process which has been selected by press-
ing STEP is executed immediately. Keep press-
ing STEP until the end of the program of the
desired cycle is reached.
