The Druck DPI620G-IS is a battery-powered, intrinsically safe calibrator and communicator designed for use in hazardous areas. It offers a comprehensive suite of electrical measure and source operations, alongside advanced digital communication capabilities for HART®, Foundation Fieldbus, and Profibus protocols. The device features a touch-screen display that can simultaneously show up to five different parameters, enhancing user efficiency and data visualization.

Function Description

The DPI620G-IS functions primarily as a versatile calibrator, capable of independent operations across five channels. Its core capabilities include:

Electrical Measure & Source Functions:
- Current (measure & source)
- Voltage (measure & source)
- Thermocouple (measure & simulate)
- Frequency (measure & source)
- Resistance (measure & simulate)
- RTD (measure & simulate)
- Pulses (measure & source)
- Observed (source): Allows manual entry of a value, such as a reading from a connected voltmeter.
Digital Communication:
- HART® Communicator: Supports Universal and Common Practice commands (HART® revision 5 to 7) and devices with Device Descriptions (DD). It can operate as a Primary Master, controlling all communications, or as a Secondary Master, communicating with field devices within an existing HART® network.
- Foundation Fieldbus Communicator: Implements the H1 protocol via an integrated H1 modem (available in DPI620G-IS-FF or DPI620G-IS-FFPB models). It supports connections to existing networks, stand-alone devices, and various network configurations.
- Profibus Communicator: Utilizes an integrated modem for PROFIBUS PA Fieldbus implementation (available in DPI620G-IS-PB or DPI620G-IS-FFPB models).
Documentation Capabilities:
- Data Logging: Records instrument readings for review and analysis, with options for periodic or key-press logging. Data is stored in a Comma Separated Variable (CSV) format, facilitating import into spreadsheet applications.
- Analysis Function: Calibrates the transfer characteristic of a device under test by taking readings from two or more DPI620G-IS channels. One channel serves as the Reference, providing the input signal, while other channels measure the output. It calculates deviation in %Span or %Rdg and indicates pass/fail results based on tolerance limits.
- Run Procedure: Executes calibration procedures downloaded from 4Sight or Intecal v10 software, including test points and ramp times.

Maintenance Features

Software and Firmware Upgrades: The device supports upgrades for the Operating System (OS), Application, HART, and CH1 FPGA software via downloadable .zip files from the manufacturer's website. The HART Device Library can also be updated.
Cleaning: The case and display should be cleaned with a lint-free cloth dampened with a weak detergent solution. Solvents or abrasive materials must not be used.
Instrument Return: For unserviceable instruments requiring repair, users must contact a GE Service Centre or Approved Service Agent to obtain a Returned Material Authorization (RMA) number. Information regarding product, serial number, defect details, and operating conditions is required.
Battery Replacement: The re-chargeable battery pack can be removed or replaced in a Hazardous Area. Recharging must be done in a Safe Area using only the GE specified charger and power supply.
Disposal: The product and its battery should not be disposed of as household waste. An approved organization for collection and recycling should be used, adhering to local health and safety procedures.
Calibration Procedures: GE provides calibration services traceable to international standards. If using an alternative facility, ensure it uses the specified standards. Calibration should be performed in a stable temperature environment (21 ± 1°C / 70 ± 2°F) after a minimum two-hour stabilization period. Specific calibration procedures are outlined for current, voltage, millivolts, TC mV, frequency, pulse amplitude, resistance, cold junction, and pressure indicator modules.
