The AMC910 multi-purpose calibrator is the right solution for high preci­sion signal, temperature, and pressure calibrations, as it combines the
power and features of a laboratory calibrator, with the addition of an iso­lated measurement channel.

It offers laboratory grade accuracy, high performance and simple-to-use
functionalities. With the optional external pressure modules, the system
may be taylored to address all possible calibration needs.

The AMC910 not only offers temperature and pressure calibration fea­tures, it combines sourcing of current and voltage, measurement of mil­livolts and resistance with a second completely isolated measurement
channel for a single laboratory calibration instrument unmatched in ver­satility, performance, and value. This flexibility means that only one unit
is needed for calibration or verification giving the confidence needed for
test instruments as well as for field calibrations.

Furthermore the AMC910 has the ability to store up to 9 setpoints for
each output range. The setpoints can be selected manually or automati­cally stepped at timed intervals. It features an intuitive, easy-to-operate
user interface and computer control through the RS232 or IEEE-488
interface for automated production testing. The unit sources DC voltage
and current for multifunction workload coverage, enabling calibration of
data loggers, strip chart recorders, multi-meters, handheld calibrators,
and other industrial instruments. This is the cost-effective solution for
multiple calibration needs.

SS-AMC910

Direct keyboard entry (1)

The JOFRA AMC910 provides simple, front-panel entry of mode,
range, and value. Using direct keyboard entry (1), the exact value
desired is entered using the numeric keys, and the ENTER key
is pressed to set the output to that value. Whichever way you
choose, setup is simple and fast. In the voltage output mode, the
JOFRA AMC910 auto-ranges on the entered value for maximum

accuracy at all times.

Curser entry (2)

Using cursor entry (2), the LEFT/RIGHT arrow keys are used to
move the cursor under the digit in the display to be changed. The
UP/DOWN arrow keys increment/decrement the value at the cur­sor position.

Pressure Mode

Signal calibration capabilities of the JOFRA AMC910 include, cur­rent, voltage and resistance. In temperature mode, the unit can read
and source any of 11 types of thermocouples and 9 RTD types as
well as YSI-400 and Ohms for non-standard curves. In pressure
mode, the instrument operates with all JOFRA APM modules and
covers pressure ranges from vacuum to 700 bar / 10,000 psi, select­able through more than 60 different pressure modules, representing
vacuum, absolute, gauge and compound pressure types as well as
all relevant pressure units with up to 0,01% Full Scale accuracy.

Setpoint Control (4 and SPT)

A SHIFT key (4) provides easy access
to the setpoint controls of the JOFRA
AMC910. Up to nine setpoints can
be defined for each output mode and
each thermocouple and RTD type.
Setpoints are recalled individually at
the touch of three buttons, SHIFT (4),
SETPOINT (SPT) button and then the
corresponding numeric keys 1-9. Any
number of sequential setpoints can
be stepped through automatically,
with complete control of dwell time.
Either way, for rapid setup of repeat­able tests, no other instrument comes
close to the JOFRA AMC910.

Choose the mode you want (3)

Voltage Mode

The JOFRA AMC910 offers four precision voltage output ranges
(100mV, 1V, 10V, and 100V) all with ±0.003% of reading ±0.001%
F. S. accuracy. These ranges are ideal for calibrating a broad
range of DC voltage instrumentation. Additionally all voltage
outputs settle to full specification in less than 200ms making the
JOFRA AMC910 ideal for automated calibration systems.

An automatic stand-by mode (3) assures that output voltages
above 30VDC must be acknowledged by the operator before the
voltage appears at the output jacks. The stand-by mode is also
triggered if the output current compliance is exceeded, thereby
protecting the device under calibration.

Current Mode

The JOFRA AMC910 features a precision current output range
(100mA) that offers 0.01% accuracy, which is ideal for calibrating
process instrumentation especially 4 to 20mA equipment. With
a full 12 volts of compliance at 100mA virtually any precision DC
current measuring device can be calibrated using the JOFRA
AMC910. Like the voltage ranges the current range offers quick
settling time and an operate/stand-by mode.

Thermocouple Mode

The JOFRA AMC910 can read and source any of 11 types
of thermocouples. Its T/C input and output is Cold Junction
Compensated, using an ultra-stable PT-1000 sensor.

RTD Mode

The JOFRA AMC910 can read and source 9 RTD types as well as
YSI-400 and Ohms for non-standard curves. Probe coefficients (A,
B, C, and R0) can be entered directly, with storage for up to five
custom curves and one SPRT curve. The performance of the JOFRA
AMC910 in the RTD mode compares to dedicated RTD measure­ment instruments. Unlike low-cost, less accurate RTD instruments,
the display in the JOFRA AMC910 is always active, reading to three
decimal places, using polynomial averaging to extract a high accu­racy signal. The result is a very high accuracy reading.

Remote Control (4)

All of the JOFRA AMC910 operating functions can be accessed
via RS232, IEEE-488 or optional USB interface cable using a
standard PC running Windows® HyperTerminal or other soft­ware using an ASCII protocol. Custom control programs may
be written using programming software such as C++. Switching
between LOCAL and REMOTE is as simple as touching the
SHIFT (4) and LOCAL buttons.

Rock-Solid Stability

The accuracy of the JOFRA AMC910 is specified for both 90-day
and one-year intervals. Manual zero calibrations can be made on
all T/C and pressure functions to eliminate offsets.

Flexible Output (5, 6 and 7)

Five-way copper alloy binding posts (5) provide a wide range of
connection options. A standard pressure module connector is
provided (6), as is the CJC T/C mini-jack (7).

Isolated Measurement Channel (8 and 9)

The JOFRA AMC910 features a fully isolated measurement chan­nel which allows the user to calibrate process transmitters and
signal isolators. In reality it’s like having two instruments in one!
This channel also incorporates a 24 volt loop power supply to
power 2-wire transmitters and a HART interface resistor enabling
direct connection to HART communicators. Key features are:

• Two voltage ranges 10V and 100V DC

• Milliamp range 0 to 50mA

• Milliamp range with simultaneous 24 volt power (0 to 24ma)

• Selectable 250 ohm HART resistor

• Accuracy of 0.005% of reading on all ranges
