8. Predefined configuration codes
Select the desired code for your application, and check the following
sections for more information:
• for information on how to activate a code, see section 13.1
• to customize the input and output signals, see section 13.4
Notes
• Code ‘ uSEr ’ indicates that a user custom configuration is active, and it does not
match any of the listed codes This code is non-selectable, for information only.
Example: select code ‘
013 ’ for 0/20 mVdc=4/20 mA, the instrument reads code
‘ 013 ’. Later, configure the input to 0/17 mVdc=4/20 mA, this does not match a listed
code, and the instrument reads ‘ uSEr ’. Or change the output to 0/20 mVdc=1/5 Vdc,
this does not match a listed code, and the instrument reads ‘ uSEr ’.
• Code ‘ ---- ’ identifies the end of the list, it follows code ‘ 199 ’ and the list
continues with code ‘ 010 ’. Select ‘ ---- ’ to exit the list without applying changes.
To calculate the optimal input signal range for your load cell,
see section 7.7.
The instrument can be configured to measure millivolt in differential
mode. Activating the millivolt mode disables de excitation voltage and
disables the ‘ sense ’ compensation for changes at the excitation voltage.
The instrument works as a pure differential millivolt signal converter.
Select the ‘ Predefined configuration code ’ according to your maximum
millivolt signal (see Table 9).
The instrument accepts up to 4 standard 350 Ohms load cells. The
instrument provides 5 Vdc excitation voltage. Calculate the maximum
output signal generated by your load cell, and select the ‘ Predefined
configuration code ’ accordingly (see Table 8).
