The conformity was established by tests described in the associated pattern evaluation report P00962 which includes 13 pages.

Characteristics of the instrument:

This pattern of an automatic discontinuous totalising instrument designated the DDxxxxHS is designed to totalise loads of powder or granular materials, and comprises a weight indicator and a weighing unit comprising of a weighing hopper supported by load cells. Additional PLCs may be used to provide various inputs, a remote PC may also be used to edit the batch and product parameters and command the operation.

Main features:

• Weight indicator

• Weighing unit

• Feeding device

• Discharge unit

• Optional printer

Weighing unit:

The weighing unit comprises a weigh hopper supported by strain gauge or digital load cells, with or without lever-works.

Load cell:

Any compatible load cell(s) may be used providing the following conditions are met:

• There is a respective OIML Certificate of Conformity (R60) issued for the load cell.

• The certificate contains the load cell types and the necessary load cell data required for the manufacturer's declaration of compatibility of modules, and any particular installation requirements. A load cell marked NH is allowed only if humidity testing to R76 has been conducted on this load cell.

• The compatibility of the load cells and indicator is established by the manufacturer by means of the compatibility of modules calculation at the time of verification.

• The load cell transmission conforms to a standard type.

Digital load cells type CPD-M and junction box type DILINK may be connected to the indicator.

Weight indicator:

The weight indicator may be one of the following:

• DD1050HS, DD1050iHS or DD2050HS (As described in OIML Certificate R76/2006-GB1-12.02)

• DD1010HS, DD1010IHS, DD1010ICHS, DD1010HHS, DD1010IHHS or DD1010ICHHS (As described in OIML Certificate R76/2006-GB1-12.14)

Note: The designation HS refers to modified software for Hopper Scale applications, the software information shall be as described in this certificate.

Devices:

• Semi-automatic zero setting device ( $ \leq $ 4% of Max)

• Net weighing

• Totalisation indicating device

• Coarse/fine feeding

• Alibi storage

• Printing

Technical data:

Maximum Capacity (Max): Dependent upon application

Minimum Load (Min): Dependent upon application

Minimum totalised load ($\Sigma_{\mathrm{min}}$): Min $ \leq\Sigma_{\mathrm{min}} $ $ \geq1000\mathrm{d}{t} $ for class 0.2 $ \geq400\mathrm{d}{t} $ for class 0.5 $ \geq200\mathrm{d}{t} $ for class 1 $ \geq100\mathrm{d}{t} $ for class 2

Scale interval ($\mathrm{d}{t}$): 0.01 % Max $ \leq\mathrm{d}{t} \leq0.2 $ % Max

Number of scale intervals (n): $ \leq6,000 $

Accuracy Class: $ \geq0.2 $

Temperature range: -10 /+ 40 $ ^{\circ}\mathrm{C} $

Rate of operation: Fixed at initial verification

Product and batch parameters: Editing prevented during automatic operation

Operation:

The weighing parameters for the totalisations (product characteristics, target weight, batch weight, coarse/fine feeding points...） can be selected via the user interface. A remote PC may also be used to edit the parameters and start/stop of automatic operation.

The instrument operates as follows:

• Totalisation parameters entered via the user interface

• Start automatic operation button pressed

• Product fed into the weigh hopper (coarse then fine)

• Product feeding stops when the weight reaches the batch weight set point

• Instrument captures the weight of the full hopper

• Product discharged until the empty weight reaches the empty weight set point

• Instrument captures the weight of the empty hopper

• Net weight calculated for the cycle

• Cycle repeated until target weight is achieved

The complete data for each totalisation is recorded on the MPP alibi memory held within the indicator, and comprises all the information necessary to reconstruct the measurement.

Note: Manual operation is not covered by this certificate and shall not be used for legal-for-trade applications. The instrument may print the weighing data for the totalisations, printouts shall not be used as legal records (Alibi records to be used as legal records).

Interfaces:

As per OIML Certificates R76/2006-GB1-12.02 and R76/2006-GB1-12.14.

Sealing:

Physical or software means as described in OIML Certificates R76/2006-GB1-12.02 and R76/2006-GB1-12.14.

The load cells and SD card shall be sealed using tamper-evident labels or wire-and-seal solution.
