1. Introduction
The
TEMP
120
is
a
20-channel
thermocouple
measurement
module.
For
sensor
connections
it
offers
universal
type
miniature
thermocouple
jacks.
An
individual
reference
junction
temperature
sensor
is
located
at
the
base
of
every
connection.
Since
the
device
is
purpose
built,
is
uses
a
simplified
data
logger
measurement
instruction
and
computes
the
compensated
temperature
on
-
board
rather
than
relying
on
a
data
logger
to
make
the
calculation.
2. Precautions
l
READ
AND
UNDERSTAND
the
section
at
the
front
of
this
manual.
l
WARNING:
o
Protect
from
over-voltage
o
Protect
from
water
o
Protect
from
ESD
(electrostatic
discharge)
l
IMPORTANT:
Maintain
a
level
of
calibration
appropriate
to
the
application.
Campbell
Scientific
recommends
factory
recalibration
of
Extended
Duty
(XD)
TEMP
120
units
every
three
years.
3. Initial inspection
l
Inspect the packaging and contents for damage immediately. File damage claims with the
shipping company.
l
Check packaging materials for all products. Check model numbers, part numbers, product
descriptions, and cable lengths against shipping documents. Model or part numbers are
found on each product. Cable numbers are normally found at the end of the cable that
connects to the measurement device. Check that expected cable lengths were received.
Contact Campbell Scientific immediately if you find any discrepancies.
l
Check the operating system version in the TEMP 120, and the data logger. Update as
needed. See
TEMP 120
