PRODUCT DESCRIPTION
The JOFRA ATC series
(Advanced Temperature
Calibrators) combines
the accuracy of laboratory temperature sources with the speed and
portability of field dryblock calibrators.
The unique dual-zone
design sets new standards for optimum temperature performancein dry-block calibrators.
Features
The JOFRA ATC-156/157/320 and 650 all features the unique dual-zone
heating block - designed for optimum performance and superior temperature homogeneity throughout the block. This new design has a performance equivalent to a liquid temperature bath. The ATC-157 features the
widest temperature range for a cooling dry-block on the market today.
Each ATC dry-block calibrator may be used to perform fully automatic
calibration routines without using an external computer. Use the computer for full upload and download capabilities. Units may also be supplied
with inputs for external reference sensors and for sensors-under-test. All
ATC calibrators feature RS232 serial communication and standard delivery also includes the JOFRACAL calibration PC software.
The ATC-156/157/320 and 650 dry-block calibrators are part of a serie of
calibrators, that also includes the ATC-140 (-20 to 140°C) and the ATC250 (28 to 250°C) available as liquid bath or large diameter dry-block
calibrators.

Advanced Temperature Calibrator
Specification Sheet
SS-CP-2285-US
Unique temperature performance
The ATC series of calibrators provide precision temperature calibration of sensors; whatever the type or format.
This is accomplished through an innovative dual-zone
heating technology.
The JOFRA ATC-156/157/320 and 650 all feature a dualzone heating technology. Each heating zone is independently controlled for precision temperature calibration. The
homogeneity in the lower part is close to that of a laboratory liquid bath. The lower zone ensures optimum heat
dissipation throughout the entire calibration zone. The
upper zone compensates for heat loss from the sensorunder-test and from the open top. This design also eliminates the need for insulation of the sensors-under-test
and makes it possible to calibrate liquid-filled and other
mechanical sensors.
MVI - Improved temperature stability
MVI stands for ’’Mains power Variance Immunity’’.
Unstable mains power supplies are a major contributor to
on-site calibration inaccuracies. Traditional temperature
calibrators often become unstable in production environments where large electrical motors, heating elements,
and other devices are periodically cycled on or off. The
cycling of supply power can cause the temperature regulator to perform inconsistently leading to both inaccurate
readings and unstable temperatures.
The JOFRA ATC-320 and ATC-650 calibrators employ
the MVI, thus avoiding such stability problems. The MVI
circuitry continuously monitors the supply voltage and
ensures a constant energy flow to the heating elements.
The JOFRA ATC-156 and ATC-157 models run on stabilized DC voltage and thus do not need the MVI circuitry.
ATC heating and cooling models
The models with both heating and cooling capabilities
(ATC-156 and ATC-157) feature the Peltier element multistage-technology. This both improves efficiency and
extends the life of the »electronic heat pump«. The JOFRA
ATC-157 offers a typical differential temperature of 68C
(122 F) below the ambient temperature.
Peltier effect (ATC-156 and -157)
In 1834, Jean Peltier, a French physicist found that an
’’opposite thermocouple effect’’ could be observed when
an electric current was connected to a thermocouple. Heat
would be absorbed at one of the junctions and discharged
at the other junction. This effect is called the ’’PELTIER
EFFECT’’.
The practical Peltier element (electronic heating pump)
consists of many elements of semiconductor material connected electrically in series and thermally in parallel. These
thermoelectric elements and their electrical interconnections are mounted between two ceramic plates. The plates
serve to mechanically hold the overall structure together
and to electrically insulate the individual elements from
one another.
Highest accuracy (model B only)
ATC series calibrators may be supplied with a built-in reference thermometer for use with an external sensor. This
feature allows one instrument to provide the freedom and
flexibility to perform calibrations at the process site while
maintaining a high accuracy.
A special 90° angled external reference sensor has been
designed to accommodate sensors with a transmitter
head, top connector or similar arrangement.
The user can decide whether to read the built-in reference sensor or the more accurate angled reference sensor
from the calibrator’s large, easy-to-read LCD display. The
external sensor and the internal sensor are independent of
one another. Downloading of reference sensor linearization
is done via a personal computer.

Advanced Temperature Calibrator
Specification Sheet
SS-CP-2285-US
SET-Follows-TRUE (model B only)
Available on B models only, the “SET-Follows TRUE”
makes the instrument tune in until the temperature of
the external reference “TRUE” meets the desired “SET”
temperature. This is used when it is critical that the temperature of the calibration zone matches the desired temperature when measured with accurate external reference
sensors.
This feature is ideal when calibrating gas correctors or
other custody transfer applications. It is also extremely
useful to calculation procedures.
Reading of sensor-under-test (model B only)
The ATC series model B is equipped with built-in converters (inputs) that enables measurement of virtually any type
of temperature sensor including:
thermostats
•
resistance thermometers (RTD)
•
thermocouples (TC)
•
transmitters
•
milliamps (mA)
•
voltage (V)
•
The ATC calibrators can be user-programmed for completely automated temperature calibrations. Once the unit
is programmed, the instrument operates itself by performing the configured calibration routine. All calibration data
is stored and available for uploading and generating exact
calibration certificates or reports.
Switch test (model B only)
Users may perform a thermoswitch test and find “Open”,
“Closed” and the hysteresis (deadband) automatically. The
instrument retains the last five tests.
Auto-stepping
Up to 20 different temperature steps may be programmed
including the hold time for each step. Upon completion of
an auto step routine, the user can easily read the results
for the sensor-under-test. Up to five (5) auto step results
are stored.
Easy-to-use, intuitive operation
All instrument settings can be performed from the front
panel. The heat source is positioned away from the panel
which helps protect the operator.
The ATC keyboard is equipped with five, positive feedback
function keys. They correspond to the text in the display
and change functionality based on instrument operations.
There are also dedicated function keys with permanent
functions.
The easy-to-read, backlit display
is large with a high contrast that
is readible even in high ambient
light conditions. The display is
easily read from all angles and
from a distance without parallax
problems. The display also features icons which help identifying
instrument conditions and operational steps, making it more intuitive to work with.
Set temperature
The “Set temperature” feature allows the user to set the
exact desired temperature with a resolution of 0.01°.
Enhanced stability
A stability indicator shows when the ATC calibrator has
reached the desired temperature and is stable. The user
may change the stability criteria, external reference and
the sensor-under-test quickly and simply. The stability
criteria is the user’s security for a correct calibration. A
count-down timer is displayed next to the temperature
read-out.
Instrument setups
The ATC series allows the user to store up to nine (9)
complete instrument setups. You may store all sorts of
information including temperature units, stability criteria,
use of external reference sensor, resolution, sensor-undertest (SUT), conversion to temperature, display contrast,
etc. The setup may be recalled at any time.
Maximum temperature
From the setup menu, the user can select the maximum
temperature limit for the calibrator. This function prevents
damage to the sensor-under-test caused by the application of excessive temperatures. The feature also aids in reducing drift resulting from extended periods of exposures
to high temperatures. This feature can be locked with an
access code.

JOFRACAL CALIBRATION SOFTWARE
JOFRACAL calibration software ensures easy calibration
of RTD´s, thermocouples, transmitters, thermoswithes,
pressure gauges and pressure switches. JOFRACAL can
be used with JOFRA DPC-500, APC, CPC and IPI pressure calibrators, all JOFRA temperature calibrators, as well
as JOFRA AMC900, ASC300 multi signal calibrator and
ASM-800 signal multi scanner.
JOFRACAL calibration software may also be used for
manual calibrations, as it can be set up to accept manual
entry of calibration data together with other liquid baths,
ice points or dry-block heat sources.
The calibration data collected may be stored on a PC for
later recall or analysis. The ATC calibrator stores the calibration procedure and may be taken out to the process
site without using a personal computer.
This allows the ATC calibrator to:
•
Operate as a stand-alone instrument, using advanced
calibration routines without the assistance of a
personal computer on site;
•
Prevent unauthorized changes to a calibration routine.
Personnel who are not authorized to alter a calibration
routine cannot do so.
As found/as left (model B only)
The JOFRA ATC series calibrator automatically handles
“As Found/As Left” calibrations. The calibrator stores both
results. The first performed calibration is “As found” and
the last performed calibration is the “As left”, regardless
of the number of calibrations/adjustments that may have
been made in between.
SYNC output
An output is located directly on the front of the ATC calibrator. This output signals when the instrument is stable
and may be used with ancillary devices such as video
recorders, digital cameras or as an input to a data logging
device. The SYNC output may be useful for automating
and documenting your calibrations when calibrating external reading devices.
Calibration (model B only)
Users may perform or read the results of the calibration
tasks directly on the instrument. When calibrating an indicating device, users may key in the results during or after the
test. Using the “Calibration info” function, the user may view
the complete calibration task, including the “Scenario” before the calibration takes place.
Calibration of up to 24 sensors with JOFRA ASM
Using the JOFRA ATC series together with the ASM
Advanced Signal Multi-scanner offers a great time-saving
automatic solution to calibrate multiple temperature sensors at the same time. The ASM series is an eight channel
scanner controlled by the JOFRACAL software on a PC.
Up to 3 ASM units can be stacked to calibrate up to 24
sensors at the same time. It can handle signals from 2-,
3- and 4 wire RTD’s, TC’s, transmitters, thermisters, temperature switches and voltage.
Please also see more in specification sheet SS-CP-2360,
which can be found at www.jofra.com
Once all calibrations are completed, the data may be
uploaded to the JOFRACAL calibration software for postprocessing and printing of certificates. The calibration data
collected may be stored on the personal computer for
later recall or analysis.
The JOFRACAL temperature
calibration software may be
donwloaded free of charge from
