Locate the instrument on a
clean workbench in an area
where the temperature is between
18 degrees Celsius and 29
degrees Celsius (65
degrees Fahrenheit and 85
degrees Fahrenheit)
and does not vary
more than plus or
minus 3 degrees
Celsius, or 5
degrees Fahrenheit.
Open the case and
raise the right panel
until completely vertical
and locked in place.
If an AC power is available,
connect the power cord
and turn the instrument on.
If the internal
battery power is used,
ensure that the batteries are
charged sufficiently to perform
the desired number of tests.
Low battery power is indicated
when the power lamp does not
illuminate.
Connect the instrument
to an AC power
source for at least 16 hours
(full charge) prior to use.
Approximately 25 tests
can then be performed.
If the battery in
a Mark 10 is not
charged sufficiently
to run a test,
an ERR-06 will be displayed,
indicating that the battery
must be recharged.
Mark 5 Deluxe and
Mark 10 instruments
are turned on by depressing the
switch (push button) marked ON.
The ON power indicator
light will alternately
pulse on and off
when the instrument
is connected to
an AC power source
and will stay on
continuously when
operated by the battery pack.
Flickering of the
power indicator light,
during any portion of a test
sequence being performed
using battery power, indicates
that recharging is necessary.
Have ready a supply of syringes,
vials, Alumicel coalescers,
syringe plugs, and pipet tips,
as well as a clean container
with distilled water.
All of the items are
furnished in the 6 pack
provided with the instrument.
In addition, have the
pipet readily available.
Syringe drive travel times
during the coalescing test
period were initially
calibrated at the factory
for each mode of operation
and have a significant bearing
on the final test results.
Both the Mark 5 Deluxe
and Mark 10 instruments
have self-check circuitry to
detect out-of-tolerance syringe
drive travel times.
Syringe drive travel times
exceeding the upper limit
will cause the final
results to measure high;
conversely, travel times
below the lower limit
will cause the final
results to measure low.
The alert indicator
lamp (marked SYR)
illuminates and depending on
the degree (more than 3 seconds)
of the out-of-tolerance
condition, three short
(1 second) tones
will also sound.
An occasional
out-of-tolerance alert
may be experienced due to some
intermittent condition, which
probably will not be indicative
of instrument failure.
However, repeated
alerts are cause
for returning the instrument
to the factory for adjustment.
During a test, the error alert
indicator will illuminate,
and ERR-03 will be
displayed indicating
an out-of-tolerance
syringe travel time.
Error alerts ERR-01
and ERR-02 will
be displayed if the syringe
stalls while traveling
up or down, respectively.
