4 Advanced Operation
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 and control response.
To avoid un careless changes of these parameters, these parameters are locked. To un-lock these
parameters use set parameter “Init Reset” to “UN-LOCKED”
Init Reset
Type Access Range FlowDDE FlowBus ModBus
Unsigned char RW 82/64 7 0/10 0x000A/11
The Init Reset parameter is used to ‘Un-Lock’ advanced parameters for writing. This parameter knows
the following values:
Value Mode Instrument action
82 LOCKED Advanced parameters are
read-only
64 UN_LOCKED Advanced parameters are
write- en readable.
This parameter is always set to “LOCKED” at power-up.
4.1.2 Identification
Serial number
Type Access Range FlowDDE FlowBus ModBus
Unsigned char[20] R - 92 113/3 0xF118..0xF11F/61721..61728
This parameter consists of a maximum 20-byte string with instrument serial number for identification.
Example: “M0202123A”
BHT Model number
Type Access Range FlowDDE FlowBus ModBus PDU
Unsigned char[14] R - 91 113/2 0xF111..0xF117/61713..61719
Bronkhorst High-Tech instrument model number information string.
Firmware version
Type Access Range FlowDDE FlowBus ModBus PDU
Unsigned char[5] R - 105 113/5 0xF128..0XF12A/61737..61739
Revision number of firmware. Eg. “V1.12”
Usertag
Type Access Range FlowDDE FlowBus ModBus PDU
Unsigned char[13] RW  - 115 113/6 0xF130..0xF136/61745..61751
User definable alias string. Maximum 13 characters allow the user to give the instrument his 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”
