Troubleshooting
Failure is unavoidable for complicated spectrometers. Here are some tips for analysis and
troubleshooting of some common anomalies.
9.1 Radiation indicator off or not flashing during measurement
Under normal circumstances, the radiation indicator keeps flashing the entire measurement
process.The indicator off or not flashing maybe caused by the followings reasons:
1. The power supply is not turned on
Cause: If the power button is not turned on, the instrument will not start work, the radiation
indicator light will not be illuminated or flashing.
Correction: Turn on the power supply before proceeding.
2. Abnormal X-ray protection system
To prevent X-ray leakage, the HV generator works only when the radiation protection system
works normally. For radiation protection system works properly, check the following:
A) Set "Auto-sensing" state. Infrared sensor switch should be located at the nosepiece, if set to the
"Auto-sensing" status, infrared sensor switch and radiation indicator will be linked, only when the
sample is located within 15mm directly in front of the infrared sensor switch, the radiation
indicator will work properly;
B) Put sample in the instrument nosepiece. Without a sample in place, the radiation indicators will
not work normally. In this case, the indicator light will be off, or go off automatically after flashing
for one second for low blank count rate.
3. Abnormal X-ray tube HV
Cause:
Unspecified
operations
may
lead
to
too
high
tube
voltage
and
current.
When
it
goes
far
enough,
the
discharge
even
damage
may
occur.
After
other
possible
causes
have
been
ruled
out,
abnormal
X-ray
tube
HV
may
be
the
reason.
. Correction:
Contact
MRC
service
center
to
have
the
X-ray
tube
HV
replaced
9.2
Smoke
or
Unusual
Noise
The
smoke
may
be
produced
by
damaged
parts
burned
out
by
short
circuits.
Unusual
noise
may
come
from
discharged
HV
supply,
if
it
is
not
the
buzzer
alarm
of
low
battery.
Using
the
instrument
in
this
state
may
cause
a
fire
or
electrical
shock.
Correction:
Immediately
turn
off
the
main
power,
plug
out
the
battery
from
the
instrument
handle
and
disconnect
the
power
cord
from
the
power
outlet.
Then
call
your
local
authorized
MRC
dealer
or
service
center

If
a
failure
occurs,
we
recommend
that
you
consult
the
troubleshooting
information
included
here.
If
after
using
the
above
troubleshooting
techniques
your
instrument
is
still
not
performing
properly,
please
do
not
open
the
instrument
for
internal
inspection,
which
may
damage
the
components
inside
or
even
compromise
your
safety.
Correction:
Please
record
the
abnormal
phenomenon
and
then
contact
your
local
authorized
MRC
dealer
or
service
center
