The SMIQ displays error and caution messages in a different manner, depending on how long, for a
short period of time or permanently, the cause exists.
Short-term message
The short-term message is displayed in the status line. Part of it
overwrites the status indications and disappears after approx. 2
seconds or in the case of a new entry.
The instrument shows, e.g., short-term messages if the attempt is
made to enter an overrange or if incompatible operating modes
deactivate one another.
Long-term message
The long-term message is displayed in the status line by means of
the message "WARNING" or "ERROR". Pressing the [ERROR] key
calls the ERROR page in which the messages are entered. Several
messages can be entered at the same time. The long-term message
remains existing until there is no cause any more. The ERROR page
is exited using the [RETURN] key.
The instrument displays, e.g., the long-term message "ERROR" if
there is a hardware error or "WARNING" if overrange settings have
been made.
Notes: – An error message "ERROR" does not necessarily point to a defect instrument. There are
various operating states which can cause an ERROR message. E. g. if the instrument is set
to external reference but no external reference is connected.
– Error 313 indicates the loss of calibration data and is also applicable in case of a cold start
(key [PRESET] is pressed during switch-on). The calibration values can be restored with
internal calibration routines. These routines are accessible via menu UTILITIES-CALIB (see
section on calibration).
The ERROR page offers access to long-term messages if the [ERROR] key is pressed.
