5.1. Advanced Setup Guide

The HPM-2002-OBE has several setup and control commands which can be accessed by using the ADJUST rotary encoder and SELECT pushbutton and at the same time viewing the display. Note that most of the commands, which are described below, can be accessed using equivalent RS232/485 commands.

The advanced setup is accessed from the Run mode. With the Run light illuminated (and not flashing), each click of the ADJUST rotary encoder in the clockwise direction will advance the display through each command. Once arriving at the desired command, the user can change the parameter (or initiate command) by pressing the SELECT pushbutton. When finished with the advanced setup, the user may return to the normal Run mode by turning the ADJUST counter-clockwise until the pressure is once again displayed. The parameters are not stored upon leaving the command and entering the normal Run mode via ADJUST. To make the changes permanent, the SAVE EEPROM command is used. Note that turning the ADJUST clockwise indefinitely will simply cycle through the commands.

Multipoint A_01, A_02, … A_FE, A_FF

The RS485 address is the multipoint address of the HPM-2002-OBE. If the unit is configured for RS232, then this parameter must set to a value of E0 or greater.
