other products.
This
machine
is
specially
used
to
test
the

set
program
curve.
The
abnormal
situation
in
the
operation,
the
screen
immediately
automatic
alarm,
display
the
cause
of failure and troubleshooting methods.
Matters needing attention
Please
according
to
the
demand
of
its
reference
as
follows
when
the choose and buy:
The temperature range: how much the
temperature range of
equipment, can
refer to the highest temperature value most
gentle
The
circulation
function:
whether
the
device
has
a
temperature
cycle function,
namely: temperature between the cyclic
switching cycle curve.
The humidity range: whether the device
with the function of
humidity
The thermal load: many
electronic products testing will power
test,
in
the
case
of
electricity,
the
products
being
tested
may
have a
fever, it will cause the load.
I
sometimes
buy
back
the
equipment,
such
as
the
standard
is
-20,
but the
temperature
does
not drop
down, it
is
for
this reason,
so be sure to
tell the manufacturer load.
The
handling
equipment:
size
please
refer
to
the
equipment,
and
equipment arrangement
position, such as door size, stair lift
size etc..
The
power: power supply test chamber size and final
placement
please refer to the equipment
is consistent or meet.
Working principle
The working principle of refrigeration:
refrigeration cycle
using
a
reverse
card
if
the
cycle,
the
cycle
of
two
isothermal
processes and two
adiabatic processes. The process is as
follows: to the high pressure
refrigerant compressed by
compressor
adiabatic, consumed power of the exhaust
temperature, after the refrigerant
through the condenser and
the
surrounding medium isothermal heat exchange heat
to the
surrounding medium. When the
refrigerant passes through the
adiabatic expansion of the shut-off
valve, the refrigerant
temperature
decreases. Finally, the refrigerant absorbs heat
from the higher temperature object
through the evaporator and
cools
the
cooling
body
down. This
cycle goes
round
and down
so
as
to
achieve
the
purpose
of
cooling.
The
refrigeration
system
of
the
test
chamber
is
composed
of
1
sets
of
freon
refrigeration
system made up
of French Taikang closed compressor.
Refrigeration system design and
application of energy
regulation
technology, which can guarantee the normal
operation
of
the
refrigeration
unit,
and
the
energy
consumption
of the
refrigeration system and refrigeration capacity
effectively
regulated,
the
refrigeration
system
is
maintained
in the best
running state. The equilibrium temperature (BTC),
both in the refrigeration system in the
case of continuous
operation, according
to the set temperature by PID automatic
operation to control the output of the
heater output control
system, and
ultimately achieve a dynamic equilibrium.
Operate the constant
temperature and humidity box
That in order to avoid the breakdown
test box with constant
temperature and
humidity, please provide the rated voltage
range of power supply.
In order to prevent the electric shock
or malfunction and
failure,
before
the
end
of
the
installation
and
wiring,
please
do
not switch on.
This product
is non - proof products, please do not have
flammable or explosive gas environment
with constant
temperature and humidity.
The instrument work please
try not to open the door open when
the
high
temperature
test
box,
may
cause
burns
to
the
operator,
open at low temperature may cause
frostbite on staff, and may
cause the
evaporator icing, affect the cooling effect. If
you
must open, please do a good job of
protection,
We prohibit
unauthorized disassembly, processing,
transformation
or
repair
of
constant
temperature
and
humidity,
Otherwise, there will be abnormal
action, electric shock or
fire risk.
We
need
to
keep
the
ventilation
hole
body
unobstructed,
to
avoid
failure,
abnormal movements, and reduce the life of fire.
If found damaged or
deformed when the machine out of the box,
please do not use.
The
machine
is
installed
when
careful
not
to
let
the
dust,
lint,
iron or other things
into, otherwise it will malfunction or
failure.
The
wiring must be correct, must be grounded.
Ungrounded may
cause
electric shock, wrong
action
accident,
abnormal
display
or large error in
measurement.
The
periodic
inspection
of
the
terminal
screw
and
a
fixed
frame,
please do not use in the loose
situation.
During
the
operation
of
instrument,
power
input
terminal
cover
must be installed on
the terminal board to prevent electric
shock.
The
instrument is in operation, before the modified
setting,
signal
output,
start
and
stop
operation,
should
fully
consider
the
safety,
the
wrong
operation
will
make
work
equipment
damage
or failure.
-
please
use
dry
cloth
to
wipe
the
instrument,
do
not
use
alcohol,
gasoline or other
organic solvents, don't splash water to the
instrument,
if
the
meter
is
immersed
in
water,
please
stop
using
immediately, otherwise there is a risk
of leakage, electric
shock or fire.
The internal parts of life
have certain instruments, for the
continued safe use of this instrument,
please conduct regular
maintenance and
maintenance. When discarding this product,
please deal with industrial waste.
We should check whether the
power supply is stable before
starting.
