Ametek ASC301, ASC-400 Specifications

ASC-400

Advanced Signal Calibrator

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 dierent types, TC: 13 dierent 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
to work with pulsed transmitters and PLC´s

Calibrate pressure and temperature

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 t into the tool box
and be operated with one hand
for easy eld 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.

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 oers 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

to calibrate and adjust a transmitter with no need for additional equip­ment.

Temperature reading at reference level

The ASC-400 oers 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.

Read-back display

The upper half of the full color 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 pressure
modules in this display section.

Primary display

This part is used for all input or
output combinations. The primary dis
play plus the read-back display gives
a full comprehensive and simultaneous
input-output functionality and an
excellent overview of the test
in progress.

Terminal block

All input and output connectors are
placed away from the display and
keyboard to give maximum freedom
to operate.

We call it the wireless keyboard…

Function keys

The function of the keys is clearly
clearly explained in the bottom of
the display.

Numeric keyboard

A full numeric keyboard gives you
the absolute fastest way to reach

-

your desired set point values.

If you choose a reference RTD from the accurate and stable JOFRA STS
temperature sensors, they are delivered with a traceable calibration
certicate including the neccessary Callendar-Van Dusen coecients.
Enter the gures 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.

Cursor keys

Set-up navigation, ne tuning of
output values, for convenient
“analog” feeling.

Fuseless protection

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!

5 “intelligent” memories

Full storage, all settings on both upper & lower channel are stored.
Customer dened memory names.

Useful large soft case (Option C)

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.

Power Supply / Charger (Option A or B)

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,
able batteries, which are

but supplemented with 6 x AA Ni-MH charge-

charged while mounted in the ASC-400.

Online % error calculation, fast and responsive
reading, for calibration and adjustment tasks

User congurable scaling, compare values in the
same format, easer than ever

Set up span, step size and timing, step and ramp
times up to 999 seconds.
