13. Configuration menu
13.1 Function codes
The fastest way to configure the instrument, is to select a predefined
configuration code (see section 8). At the ‘ Configuration code ’ ( codE )
parameter use keys ‘ UP ’ (
5
) and ‘ LE ’ (
3
) to move up and down
through the list of codes. Locate the desired code, and press ‘ SQ ’ (
<
).
The instrument shows the ‘ codE ’ parameter. Press ‘ LE ’ (
3
) to exit the
‘ configuration menu ’. The instrument stores the new configuration,
applies a ‘ power-up ’ routine and returns to the ‘ normal mode ’ of operation
(see section 12.2).
Selecting a ‘
reserved ’ code or ‘ ---- ’ returns to the previous menu without
changes.
When entering the ‘
Function code ’ ( codE ) parameter, the active
‘ configuration code ’ is displayed. If the actual configuration does not
match any of the configuration codes, code ‘ uSEr ’ is displayed.
There are different codes for 4/20 mA output (codes from 010 to 099)
and 0/10 Vdc output (codes from 110 to 199) (see section 8).
Custom input and output signal ranges can be configured at the
‘ Advanced scaling ’ section of the ‘ configuration menu ’ (see section 13.4).

(see Table 8)
13.2 Initial configuration
At the ‘ Input configuration ’ ( InP ) menu entry, configure the reading
mode and the input signal range.
If you have already selected a configuration code (see section
13.1), the input signal has been already selected and there is
no need to manually select the ‘ Mode ’ ( ModE ) or ‘ Signal range ’
( rAnG ) parameters again.
At the ‘ Mode ’ ( ModE ) parameter select ‘ cELL ’ for load cell measurement,
or select ‘ MV ’ for millivolt measurement. See section 7.2 and 7.3 for an
explanation of the differences between both modes.
At the ‘
Signal range ’ ( rAnG ) parameter select the input signal range.
Input signal ranges can also be configured by selecting a pre-defined
configuration code (see section 13.1).
For an example on how to calculate the appropriate input signal range
for a given load cell, see section 7.7.
To customize to an intermediate range (for example 0/7.5 mV) see
section 13.4. To manually select the output signal see section 13.3.
At the ‘
Excitation voltage ’ ( V.EXc ) parameter select ‘ oFF ’ to disable the
excitation voltage. Excitation voltage is set to ‘ on ’ when selecting the
‘ cELL ’ mode, and set to ‘ oFF ’ when selecting the ‘ MV ’ mode at the ‘ Mode ’
( ModE ) parameter.
13.3 Output range
At the ‘ Output range ’ ( out ) menu entry, select the output signal range to
4/20 mA (value ‘ 420 ’) or to 0/10 Vdc (value ‘ 010 ’).
The output signal range selected can be later customized to operate in a
reduced range of signal (see section 13.4).
