Simple, Intuitive Interface
The 3001
Millennium
calibrator
provides simple, front-panel entry
of mode, range, and value, using
either direct key-board entry
or cursor entry. Using cursor
entry, 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. Using direct
keyboard entry , 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 3001
auto-ranges on the entered value
for maximum accuracy at all times.
The
Performance You Demand – In Any
Mode
Thermocouple Mode
The
Martel 3001 can read and source any
of 11 types of thermocouples. Its
Thermocouple input and output is
Cold Junction Compensated, using an
ultra-stable PT-1000 sensor.
RTD Mode
The 3001
can read and source 9 RTD types as
well as YSI 400 Series Thermistors 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 3001 in the RTD mode compares
to dedicated RTD measurement
instruments. Unlike low-cost, less
accurate RTD instruments, the
display in the 3001 is always
active, reading to three decimal
places, using polynomial averaging
to extract a high accuracy signal.
The result is a very quiet, high
accuracy reading.
Voltage
Mode
The 3001
offers four precision voltage
output ranges (100mV, 1V, 10V, and
100V) all with 0.003% (30ppm)
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 3001
ideal for automated calibration
systems. An automatic stand-by mode
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 3001 features a precision
current output range (100mA) that
offers 0.01% (100ppm) 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 3001. Like the voltage
ranges the current range offers
quick settling time and an
operate/stand-by mode.
