Calibrate touch screen with finger or stylus. If this is not possible: Start factory
calibration through web access.
No trend line available.
Configure the logger in the appropriate probe.
Communication problems
Check the probe plug, check probe cable damage, check network plug and cable at
sc1000 networks.

turned off
Check the fuses, if the probe module is connected to power supply.
Missing measured values after
changing probe (mA output card,
fieldbus card)
New configuration for the output cards is necessary. Configure the new probe with its
serial number. After that, delete the not used probe in the device management.

Errors are indicated with a red background in the according displayed measurement
value.
Screen is blue, no measurements
are displayed
Check if the probes are connected. If the probes are connected, scan for new
devices. Check the measurement screen configuration. If no device is configured add
it to the measurement screen configuration.
New devices (probes, modules) are
connected to the sc1000 controller
but were not listed during initial bus
scan
Check whether missing devices are connected to local or – when installed – to
remote probe modules. Use the serial numbers for identification.
For remote probe modules check proper termination of all network cables.
For local probe modules retry with interchanged device connectors.
