    Wiring Diagram:

    The PD6100 is a member of the ProVu series of 1/8 DIN digital panel meters that accepts strain gauge & load cell inputs and mV signals up to 300 mV (unipolar) and ± 250 mV (bipolar) for weight indication and force measurement applications. The PD6100’s dual-line display and powerful dual-scale capability allows the measurement to be displayed in two different units of measure; gallons (volume) could be displayed on the upper line while pounds (weight) is displayed on the lower line, for example. Another use for the PD6100’s dual-line display is to simply show the units of measure on the bottom line. The PD6100 stain gauge meter includes a 5 or 10 VDC power supply to drive the sensors and can be equipped with up to four internal relays and one 4-20 mA output.

    Load Cell

    A typical application for load cells is in a tank weighing operation. In the following example, this three-legged tank has a load cell under each leg. The three load cells are wired locally in parallel within a junction box. The combined signals are then connected to the PD6100. During field calibration, the weight of the empty tank (zero point) and the full tank weight (full scale) are programmed into the meter. Over time, the tare feature on the PD6100 can account for obstacles like sludge buildup on the bottom of the tank when empty.

    MeterView® Pro Software

    MeterView Pro VideoMeterView® Pro software is designed for use with ProVu, ProtEX-MAX, or Helios Series meters and allows users to remotely program, monitor, and datalog using a PC. Remote programming allows for all available meter settings to be programmed through an easy, user-friendly interface. The data acquisition feature allows the user to gather readings from a meter at user-selected intervals and generate charts using common tools like Microsoft® Excel. A linearization setup function is also included. With this utility the user can configure up to 32 linearization points and upload them to the meter. All configuration data can be saved to a file for future use.
    This software is accessible via the onboard USB connection on all Helios large display meters, ProVu panel meters, and ProVu-based ProtEX-MAX explosion-proof meters produced since 6 September 2016 (firmware version 4.0 or higher). In order for meters produced prior to 6 September 2016 (firmware version 3.1 or lower) to establish digital communications with a PC, a serial communications adapter is required. For an RS-232 connection, use a PDA1232 adapter.
    To determine the software version of a meter:

    1. Go to the Diagnostics menu () and press Enter button.
    2. Press Up arrow button and scroll to Information menu (Info).
    3. Press Enter to access the software number (), version (), and serial number () information. Write down the information as it is displayed. Continue pressing Enter until all the information is displayed.
    4. The meter returns to Run Mode after displaying all the settings.
