Problem
No weight displayed
with a load on the scale.
0.0 does not appear
before weighing.
One segment is illumi-
nated either continu-
ously or not at all.
The display "StOP"
appears.
The display "tEMP"
appears.
After switching on for
the first time, measure-
ment results are trans-
mitted and two beeps
are heard.
Only the "SYS" item is
visible in the "rF" menu.
Cause / Solution
The scale has no power supply.
- Check whether the scale is switched on.
A load was already on the scale before it was
switched on.
- Remove the load from the scale.
- Switch the scale off and back on again.
The corresponding point has a fault.
- Inform the service department.
Maximum load has been exceeded.
- Remove the load from the scale.
The ambient temperature of the scale is too high
or too low.
- Set up the scale in an ambient temperature
between +10 °C and +40 °C.
- Wait for around 15 minutes until the device
has adapted to the ambient temperature.
• The device was unable to send measurement
results to the wireless receiver (seca wireless
printer or PC with seca USB wireless adapter).
- Ensure that the scale is integrated in the
wireless network.
- Ensure that the receiver is switched on.
• Reception is being interfered with by HF equip-
ment (e.g. cell phones) in the vicinity.
- Keep HF equipment at least 1 meter away
from transmitters and receivers in the seca
wireless network. The actual transmission
output of HF equipment may require mini-
mum distances of more than 1 meter. For
details, go to www.seca.com.
NOTE
If this fault is not eliminated, there will be no
fresh acoustic warning when further
attempts are made to send data.
• The wireless module is deactivated.
- Activate wireless module (see "Activating the
wireless module (SYS)" on page 85).
