Ametek ASC300
Shown
|
|
|
|
|
The ASC300 is substantial enough to cover all needs for a process signal
calibrator with superior accuracy and com-pact enough to fit into the
tool box and operate with one hand for easy field calibration.
The ASC-300 can change the entire calibration regimen for signal,
pressure, and temperature. It may be combined with the APM external
pressure modules or a Ametek dry-block calibrator to meet any
calibration needs.
This signal calibrator combines a full numerical keypad with a series of
function keys and a graphical user interface making it easy to perform
various tasks in a short period of time. This advanced calibrator
employs the latest technology in supporting your calibration needs.
This product measures and sources: TCs, RTDs, current, voltage,
frequency, and pulse trains. It is also designed to be compatible with
the APM pressure modules and thus offering multi-function operability.
There are two channels of operation providing the user with an isolated
read-back circuit. The graphical display makes it is easy to recognize
the status of the instrument, take readings, and simulate different
functions. |

Details |
|
Read-back display |
The upper half of the graphical
display is dedicated to the read-back signal from the
device-under-test. This input section is electrically
isolated from the circuitry. You can also read pressure from
the Ametek APM pressure modules in this display section. |
|
Primary display |
This part is used for all input
or output combinations. The primary display plus the
read-back display gives a full comprehensive and
simultaneous input-output functionality and an excellent
overview of the test in progress. |
|
Soft Keys |
Three navigation keys. Their function is
clearly explained in the bottom of the display. |
|
Backlight ON / OFF |
Turn the back light on in dark
environments. |
|
Numeric keyboard |
A full numeric keyboard gives
you the absolute fastest way to reach your desired set
values. |
|
Terminal block |
All input and output connectors
are placed away from the display and keyboard to give you
the maximum freedom to operate the unit. |
|
"Never get lost" - HOME key |
This key sends you immediately
back to the main operating display without making any
changes to the setup. |
|
Communication connection |
Small stereo jack connector for
the serial communication inter-face. |
|
Fast stepping keys |
Just one push of a button and
you can output null (0%) or full span (100%) of your desired
range. The 25% button cycles the output in 25% steps up or
down each time you push it. |
|
Pressure modules |
LEMO connector in the bottom of
the instrument to provide easy connection for the entire
range of Ametek APM pressure modules. |
|
|
|
Simultaneous input and output
The Ametek ASC300 offers simutaneous input and output. This means
that you can calibrate and adjust a tempera-ture transmitter on the
table with no other necessary instruments.
Output the sensor signal and input the mA from the trans-mitter. If you
select mA Loop the Ametek ASC300 will also supply the 24 VDC for the
loop. In the display you will see both your output temperature and the
return mA from the transmitter. Enter the zero and full scale values and
you can make quick 25% steps or go direct to zero or full span values.
The Ametek ASC300 has dedicated keys for this operation so adjustment on
the transmitter is made easier.
Temperature reading at reference level
The Ametek ASC300 offers the possibility to characterize an RTD
sensor. Use this feature to add a missing special curve or to
characterize a reference RTD.
If you choose a reference RTD from the Ametek STS100 series of high
accurate and stable temperature sensors, they will be delivered with a
traceable calibration certificate including the necessary Van Dusen
coefficients. Enter the figures into the JOFRA ASC300 and you have a
temperature reference. Complement this with a Ametek dry-block
temperature calibrator and your Ametek ASC300 becomes the heart of your
portable calibration lab.
Fuseless protection
If you, by mistake, connect the Ametek ASC300 to the mains supply,
the instrument is protected with a fuseless protection feature. This
feature protects the instrument on up to 240 VAC on any combination of
connections made on the test lead connectors and prevents expensive
repairs and recalibration of the instrument.
JOFRACAL Calibration Software
The JOFRACAL calibration software ensures easy calibration of RTD´s,
thermocouples, transmitters, thermoswitches, pressure gauges and
pressure switches. JOFRACAL can be used with Ametek DPC-500, APC, CPC
and IPI pres-sure calibrators, all Ametek temperature calibrators, as
well as Ametek 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 ITC calibrator stores the
calibration procedure and may be taken out to the process site
without using a personal computer. Once all calibrations are
completed, the data may be uploaded to the JOFRACAL calibration
software for post-processing and printing of certificates. The
calibration data collected may be stored on the personal computer
for later recall or analysis.
