Warnings and errors
Device-internal warnings and errors are output via the digital display. The device continues to
measure if there are pending warnings. The output signal and the switching outputs continue to be
output.
The following table shows the codes and their meaning.
Warning Description
ATT1
When the switching point was changed, the reset switching point was automatically
lowered by the smallest hysteresis of 0.25% by the device.
ATT2 Zero point offset, prevailing pressure outside the limits
ATT3 Password entry for menu access faulty
ATT4 Unit cannot be shown on the display, previous unit is used
