D-R 290 135
Any one of the four measurement channels can be assigned to the analogue output.
The output value of this measurement channel is then output at the analogue output.
The analogue output range is determined by the signal range start/end setting in the
measurement channel or by the setting of the current loop output range start/end in
the analogue output settings.
Signal range start: Measured value for 4 mA
Signal range end: Measured value for 20 mA
Setting the analogue output
Left click on "Device" in the sitemap.
Left click on for the desired device in the device list.
Under

Save Parameters
For security reasons, parameters that are changed (e.g. specific parameters such as
data for gravimetric calibration) are initially written only to the working memory of the
device. This means these data are currently used or referenced, but are no longer
available after the device has been restarted (i.e. the device then reverts to using the
"old" parameters).
Clicking on the "Save parameters" button causes the data to be transferred to the
read-only memory of the device. This means the parameters are also retained and
continue to be used even the device is restarted.
For the new setting to be used permanently, left click on the "
Save parameters
"
button. (The new setting is not used permanently until it has been saved.)
Relay settings
The measuring head has two potential-free relay outputs available. The relay outputs
can be assigned to an event or a combination of events.
The setting is performed in the following way:
