Description
The model CTR5000 precision thermometer also comes with
two channels as standard, but four and six channel variations
are available with each channel able to work with up to 70
user-dened probes so providing spot on calibration.
It can also provide a sequential channel scan with a data
logging function that can also be sent to PC or USB memory
stick. The CTR5000 also oers single, dierential and
alternative measurement modes with the ability to provide
direct comparison calibration.
Using calibrated probes with the precise thermometer
choose between storing the calibration data into the memory
of the instrument or if using ASL SMART probes can be
entered into these.
Precision thermometer model CTR5000 with model
CTS5000 multiplexer
The SMART probe data can also be reviewed and edited
therefore easy calibration of ASL SMART probes. The
instrument can also generate coecients from reference
temperature/resistance data pairs.
The instrument is capable of measuring temperature ranges
to meet ITS 90, CVD, EN 60751 and IEC 751 standards and
results are delivered via a LCD backlit display with large
numeric, statistical or graphical information. It also comes
with USB interface as standard, but optional RS-232, IEEE or
LAN interfaces are also available.
To ensure long term reliability the precision thermometer
uses surface mount technology with no mechanical relays or
potentiometers.

Options
With DIN plug or SMART plug
With ASL's SMART connector on the probes, storing the data
is needed only once - in the connector! The calibration data
stays with the probe - permanently. It can even be used on
another instrument without any further action.
Viewed from top panel
Shield
The SMART connector saves time and reduces error. If there
are existing calibrated or uncalibrated probes, no problem,
CTR5000 automatically registers if a probe is SMART or
normal.

Operation
The instrument’s keys are grouped by type and consist of
six soft-keys and a twelve-key numerical keypad. The soft
keys are used to access data and/or functions within the
instrument.
The CTR5000 keypad is shown in detail below. The keys
are used to select the various functions and menu options
The soft-keys are used to select common functions, Chan,
Zero, Hold and Unit. The blue display key is used to select
other display modes. All other settings and functions are
accessed via the menu key. The numeric keypad is used to
enter numerical values or to directly select a measurement
channel 10 or menu.
and to control the instrument. Generally, all commonly used
functions are available at the top level and no more than
one or two menu levels are below the other commonly used
settings. A few (infrequently used options) require three or
four menu levels.
