FEATURES AND APPLICATIONS
The Model 1056 dual-input analyzer offers single or
dual sensor input with an unrestricted choice of dual
measurements. This multi-parameter instrument offers
a wide range of measurement choices supporting most
industrial, commercial, and municipal applications.
The modular design allows signal input boards to be
field replaced making configuration changes easy.
Conveniently, live process values are always displayed
during programming and calibration routines.
QUICK START PROGRAMMING: Exclusive Quick
Start screens appear the first time the Model 1056
is powered. The instrument auto-recognizes each
measurement board and prompts the user to configure
each sensor loop in a few quick steps for immediate
deployment.
DIGITAL COMMUNICATIONS: HART and Profibus
DP digital communications are available. Model 1056
HART units communicate with the Model 375 HART
®
hand-held communicator and HART hosts, such as
AMS Intelligent Device Manager. Model 1056 Profibus
units are fully compatible with Profibus DP networks
and Class 1 or Class 2 masters. HART and Profibus
DP configured units will support any single or dual
measurement configurations of Model 1056.
MENUS: Menu screens for calibrating and programming
are simple and intuitive. Plain language prompts and
help screens guide the user through these procedures.
DUAL SENSOR INPUT AND OUTPUT: The Model
1056 accepts single or dual sensor input. Standard
0/4-20 mA current outputs can be programmed to
correspond to any measurement or temperature.
ENCLOSURE: The instrument fits standard ½ DIN
panel cutouts. The versatile enclosure design supports
panel-mount, pipe-mount, and surface/wall-mount
installations.
ISOLATED INPUTS: Inputs are isolated from other
signal sources and earth ground. This ensures clean
signal inputs for single and dual input configurations.
For dual input configurations, isolation allows any
combination of measurements and signal inputs without cross-talk or signal interference.
TEMPERATURE: Most measurements require temperature compensation. The Model 1056 will automatically recognize Pt100, Pt1000 or 22k NTC RTDs built
into the sensor.
SECURITY ACCESS CODES: Two levels of security
access are available. Program one access code for
routine calibration and hold of current outputs; program
another access code for all menus and functions.

DIAGNOSTICS: The analyzer continuously monitors
itself and the sensor(s) for problematic conditions.
The display flashes Fault and/or Warning when these
conditions occur.
DISPLAY: The high-contrast LCD provides live
measurement readouts in large digits and shows up to
four additional process variables or diagnostic
parameters. The display is back-lit and the format can
be customized to meet user requirements.
LOCAL LANGUAGES :
Rosemount Analytical extends its worldwide reach by
offering seven local languages – English, French,
German, Italian, Spanish, Portuguese, and Chinese.
Every unit includes user programming menus; calibration
routines; faults and warnings; and user help screens
in all seven languages. The displayed language can
be easily set and changed using the menus.
CURRENT OUTPUTS: Two 4-20 mA or 0-20 mA current
outputs are electrically isolated. Outputs are fully scalable
and can be programmed to linear or logarithmic
modes. Output dampening can be enabled with time
constants from 0 to 999 seconds. Output 1 includes
digital signal 4-20 mA superimposed HART (option -HT
only)
SPECIAL MEASUREMENTS: The Model 1056 offers
measuring capabilities for many applications.
Single or Dual Turbidity: Ideal in municipal appli-
cations for measurement of low-NTU filtered drinking
water. Must be used with Clarity II sensor, sensor cable
and debubbler.
4-Electrode Conductivity:
The Model 1056 is compatible with Rosemount
Analytical 4-electrode Model 410VP in the PUR-SENSE
family of conductivity sensors. This sensor supports
a wide array of applications and is capable of measuring
a large range of conductivity with one geometric
configuration. Wired to the Model 1056, this sensor
can measure 2μS/cm to 300mS/cm with an accuracy of
4% of reading throughout the entire range.
4-20mA Current Input: Accepts any analog current
input from an external device for temperature compensation of measurements and atmospheric pressure
input for partial pressure correction of oxygen.
Selective Ions: The analyzer is able to measure
ammonia and fluoride using commercially available
ion-selective electrodes. All analyzers with installed pH
boards can be programmed to measure selective ions.
pH Independent Free Chlorine: With Rosemount
Analytical’s Model 498Cl-01 sensor, the analyzer is
able to measure free chlorine with automatic correction
for process pH without the need for a pH sensor.
Inferential pH: The analyzer is able to derive and
display inferred pH (pHCalc) using two contacting conductivity signal boards and the appropriate contacting
conductivity sensors. This method will calculate the
pH of condensate and boiler water from conductivity
and cation conductivity measurements.
Differential Conductivity: Dual input conductivity
configurations can measure differential conductivity.
The analyzer can be programmed to display dual
conductivity as ratio, % rejection, or % passage.

Measures conductivity in the range 0 to 600,000 μS/cm
(600mS/cm). Measurement choices are conductivity,
resistivity, total dissolved solids, salinity, and % concentration. The % concentration selection includes the
choice of five common solutions (0-12% NaOH, 0-15%
HCl, 0-20% NaCl, and 0-25% or 96-99.7% H2SO4).
The conductivity concentration algorithms for these
solutions are fully temperature compensated. Three
temperature compensation options are available:
manual slope (X%/°C), high purity water (dilute sodium
chloride), and cation conductivity (dilute hydrochloric
acid). Temperature compensation can be disabled,
allowing the analyzer to display raw conductivity. For
more information concerning the use and operation of
the contacting conductivity sensors, refer to the product
data sheets.
Note: When two contacting conductivity sensors are
used, Model 1056 can derive an inferred pH value
called pHCalc. pHCalc is calculated pH, not directly
measured pH. (Model 1056-01-20-30-AN required)
Note: Selected 4-electrode, high-range contacting
conductivity sensors are compatible with Model 1056.
Input filter: time constant 1 - 999 sec, default 2 sec.
Response time: 3 seconds to 100% of final reading
Salinity: uses Practical Salinity Scale
Total Dissolved Solids: Calculated by multiplying
conductivity at 25ºC by 0.65

Measures conductivity in the range of 1 (one) μS/cm to
2,000,000 μS/cm (2 S/cm). Measurement choices are
conductivity, resistivity, total dissolved solids, salinity,
and % concentration. The % concentration selection
includes the choice of five common solutions (0-12%
NaOH, 0-15% HCl, 0-20% NaCl, and 0-25% or
96-99.7% H
2SO4
). The conductivity concentration
algorithms for these solutions are fully temperature
compensated. For other solutions, a simple-to-use
menu allows the customer to enter his own data. The
analyzer accepts as many as five data points and fits
either a linear (two points) or a quadratic function (three
or more points) to the data. Two temperature compensation options are available: manual slope (X%/°C) and
neutral salt (dilute sodium chloride). Temperature
compensation can be disabled, allowing the analyzer to
display raw conductivity. Reference temperature and
linear temperature slope may also be adjusted for
optimum results. For more information concerning the
use and operation of the toroidal conductivity sensors,
refer to the product data sheets.
