Precision Digital ProtEX-MAX™ PD8-7000 offers all the functionality of the ProVu PD7000 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It accepts direct temperature input from a wide range of temperature measurement devices (type J, K, T, E, R, S, B, N, and C thermocouples and 100 or 1000 Ω platinum, 10 Ω copper, 120 Ω nickel RTDs). It displays the measured temperature in either degree Fahrenheit or degrees Celsius on a dual-line, 6-digit Sunbright sunlight-readable display. The meter includes automatic cold junction compensation for thermocouples and the ability to average up to ten (10) RTD sensors. The PD8-7000 can be equipped with up to four internal relays and a 4-20 mA analogue output. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons or the RS485 serial communication port with free Modbus® protocol.

MeterView® Pro Software
MeterView® 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 PDA1232adapter.
To determine the software version of a meter:
- Go to the Diagnostics menu () and press Enter button.
- Press Up arrow button and scroll to Information menu (Info).
- 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.
- The meter returns to Run Mode after displaying all the settings.
