MULTI PARAMETER UNIT Check
This item checks the communication with the DPU board, function and accuracy of
the multi-parameter inputs. The CPU on the MP2 board sends the check result and
multi-parameter socket status data to the DPU board.
Procedure to Start the MULTI PARAMETER UNIT Check Program
To select the MULTI PARAMETER UNIT Check, touch the “MULTI
PARAMETER UNIT CHECK” key at the COM CHECK column.
• POWER ON RESULT: Displays the result checked by the CPU on the MP2 board
at the power on self check. If an error is found, one of the following error codes
appears on the screen.
Error Code Description Action
ROM
The ROM on the MP2 board is
faulty.
Replace the MP2 board with a
new one.
RAM
The RAM on the MP2 board is
faulty.
Replace the MP2 board with a
new one.
A/D
The A to D converter on the
MP2 board is faulty.
Replace the MP2 board with a

when the corresponding connection cord is connected to each
multi-parameter socket. If the socket has no connection cord, “NONE” appears.
• LOOP CHECK: Displays “ERROR” when the one of the connection cords is
connected to the socket or no connection cord is connected. Only if the factory
use connector for the loop check is connected to the socket, “OK” appears.
• EEPROM data: Displays the data of the EEPROM in the connector of the
connection cord when it is connected to the socket. When no connection cord is
connected, all the data shows “0FFF”. If there is a communication error between
the DPU board and CPU on the MP2 board, all the data shows “8000”. In this
case, the DPU board, motherboard or MP2 board will be faulty.
