Advanced Signal Calibrator  ASC-400

Ametek ASC-400

Ametek ASC-400

User friendly and innovative 

Advanced Simplicity

Optimal read out visibility and high accuracy
Large full color display and extremely user friendly interface. The ASC-400 accuracy is designed to meet high demands
from modern sensores and transmitters

Input and output
RTD: 16 different types, TC: 13 different types, Current 0-24 mA DC, Voltage 0-20 VDC, Frequency 0.05 to 10,000 Hz,
Pulse train out-put, Resistance 5 to 4000 ohm 

Simultaneoues read-back and fast RTD simulation
Including isolated read-back from device-under-test of mA, V, and pressure. The RTD simulation feature is fast enough

Calibrate pressure and temperature
Full featured pressure calibrator, just apply an APM, and benefit from, automatic leak-test, pressure-switch calibration
and more… Use the ASC-400 together with JOFRA temperature calibrators, add measurement channels for sensors
or temperature switches

Measure temperature
ASC-400 can be used as high accuracy thermometer, ASC-400 works with RTD´s and CvD equations, to obtain true
temperature, based on “true ohm” technology!

ASC-400 is a portable process 

signal calibrator that provides the

functionality and accuracy

you expect from a laboratory
calibration system, but compact
enough to fit into the tool box
and be operated with one hand
for easy field calibration.
The ASC-400 is more than just a
signal calibrator. Combined with
our APM external pressure modules
or our dry-block calibrator,
it will calibrate pressure and
temperature, and used together
with JOFRACAL even document
it as well.
The full numerical keypad with
a series of function keys and the
cursor keys, provide a simple
and quick user interface. The
new full color display offers the
best visibility and overview.
The high accuracy of ASC-400
has not been achieved on
account of fragile measurements
or source circuitries, the
ASC-400 has fuse less protection
– no lost replacement fuses...

Unique “non-menu” user interface
Easy to use, single layer user interface, no deep menu structure!
Operate and set up ASC-400 to perform your tasks, fast and intuitive

Simultaneous input and output

ASC-400 offers simutaneous input and output, which makes it possible
to calibrate and adjust a transmitter with no need for additional equipment.

Temperature reading at reference level
The ASC-400 offers the possibility to charaterize a RTD sensor. This feature
is used to add a missing special curve or to characterize a
reference RTD. This together with “true ohm” technology, eliminating
thermo voltage in the RTD loop, makes ASC-400 a true reference thermometer.
If you choose a reference RTD from the accurate and stable JOFRA STS
temperature sensors, they are delivered with a traceable calibration
certificate including the neccessary Callendar-Van Dusen coefficients.
Enter the figures into the unit and you have a temperature reference.
Complement this with a dry-block temperature calibrator and your
ASC-400 becomes the heart of your portable calibration lab.

Fuseless protection
Useful large soft case (Option C)
If you by mistake connect the ASC-400 to over voltage, the unit is protected
with a fuseless protection feature. This feature protects the unit
and prevents expensive repairs and recalibration of the unit.
To avoid injury never connect the unit to the mains supply!
As an option you can get the ASC-400 delivered with a large padded
soft case. The spacey soft case is designed for protection during transport.
The soft case has separate compartments for the unit, test leads,
test hoses, temperature probe, and APM pressure modules. A shoulder
strap ensures convenient and safe transportation when climbing ladders,
etc.
As standard the ASC-400 is delivered with 6 AA alkaline batteries.
Additionally two power supply options are available;
Option A, mains adapter, used as battery eliminator to preserve batteries
in long term workshop testing & calibration.
Option B, like Option A, but supplemented with 6 x AA Ni-MH chargeable
batteries, which are charged while mounted in the ASC-400.
 

Gauge or Absolute pressure? (Option BARO)
APM Pressure Modules (Accessory)
The choice is yours!
The BARO option turns any gauge
measuring APM into an absolute
measuring device.
Accuracy: ± 0.5 mbarA / 0.00725 psiA
Range: 700 to 1100 mbarA / 10.153 to 15.954 psiA
Includes all effects of linearity, hysteresis, temperature (-10 to 50°C /
14 to 122°F) and stability for one year.
Please note the BARO option is factory installed.
When used with APM CPF Series pressure modules the ASC-400 becomes
a true pressure calibrator with features such as; leak test, switch
test, scaling and online % error calculations.
Pressure range from vacuum to 1 000 bar / 15 000 psi, accuracies down to
0.025% RDG, fully temperature compensated, and stability for one year.
The modules are engineered for in-plant, field, or laboratory use. They
are ready-to-use with immediate recognition and use of the module
once plugged into the calibrator. All units are welded, with a permanent
filled diaphragm seal. Metal to metal cone seal, and O-ring. CPF
adapters to various threading available.
Up to 14 built-in engineering units
Automatic leak test, adjustable timer and automatic
calculation to leak rate / minute
Automatic pressure switch test, records automatically,
open, close and deadband values
Online % error calculation, fast and responsive
reading, for calibration and adjustment tasks

JOFRACAL calibration software
JOFRACAL software ensures easy calibration of RTD´s, thermocouples,
transmitters, thermoswithes, pressure gauges and pressure switches.
JOFRACAL can be used with all calibration instruments. When used
with an ASM-800 signal multi scanner, it can perform a simultaneous
semi automatic calibration on up to 24 pressure and/or temperature
devices under test in any combination.
JOFRACAL software controls the complete calibration procedure, stores
the results and provides a calibration audit trail through hard-copy
certificates. All calibration data are stored for each sensor to monitor
drift and optimise recalibration intervals. A scheduler feature allows
planning of future calibrations.
