4.1 Reading and changing instrument parameters
4.1.1 Introduction
All parameters described in this chapter have influence on the behaviour of the mass flow meter. Please
be aware that wrong settings can disorder the output.
To avoid unintential changes of these parameters, these parameters are locked. To unlock these
parameters use set parameter “Init Reset” to “UN_LOCKED”
Init Reset
Type Access Range FlowDDE FLOW-BUS
Unsigned char RW 82/64 7 0/10
The Init Reset parameter is used to ‘unlock’ advanced parameters for writing. This parameter can be set to the
following values:
Value Mode Instrument action
82 LOCKED Advanced parameters are
read-only
64 UN_LOCKED Advanced parameters are
writeable and readable.
This parameter is always set to “LOCKED” at power-up.
4.1.2 Identification
Serial number
Type Access Range FlowDDE FLOW-BUS
Unsigned char[20] R - 92 113/3
This parameter consists of a maximum 20-byte string with instrument serial number for identification.
Example: “M0202123A”
BHT Model number
Type Access Range FlowDDE FLOW-BUS
Unsigned char[14] R - 91 113/2
Bronkhorst High-Tech instrument model number information string.
Firmware version
Type Access Range FlowDDE FLOW-BUS
Unsigned char[5] R - 105 113/5
Revision number of firmware. Eg.: “V1.12”
Usertag
Type Access Range FlowDDE FLOW-BUS
Unsigned char[13] RW - 115 113/6
User definable alias string. Maximum 13 characters allow the user to give the instrument its own tag name.
It is advised here to limit the name up to 7 characters when using E-7000 readout and control modules.
These modules can display the tag name of an instrument only up to 7 characters. Eg.: “Room1s6”
