Saving a measured value with differing electrical circuit parameter
The electrical circuit parameter you have set at the test instrument does 
not correspond to the parameter saved in the structure under object data. 
Example: The residual operating current defined in the database is 10 mA, 
whereas you have performed measurements with 100 mA. If you wish to 
perform all future measurements with 100 mA, the value must be modi-
fied in the database by acknowledging it with  . The measured value 
will be documented and the new parameter will be accepted.
If you wish to leave the parameter in the database unchanged, press key 
. Measured value and modified parameter will only be documented.
All Please enter a designation (alphanumeric).

Operation with a Barcode Scanner
Error message appears when the “EDIT” entry field is opened and battery 
voltage is less than 8 V. Output voltage is generally switched off during 
barcode scanner operation if U is less than 8 V in order to assure that 
remaining battery capacity is adequate for entering designations for 
devices under test and saving the measurement.
Remedy: Rechargeable batteries must be recharged, or replaced towards 
the end of their service life.
All
Operation with a Barcode Scanner
Current flowing through the RS 232 port is too high.
Remedy: 
The connected device is not suitable for this port.

Operation with a Barcode Scanner
Barcode not recognized, incorrect syntax
All
Data cannot be entered at this location within the structure.
Remedy: Observe profile for preselected PC software (see SETUP menu).
All
Measured value cannot be saved at this location within the structure.
Remedy: Make sure that you have selected the right profile for you PC 
evaluation program in the SETUP menu (see section 4.6).
All
Memory is full.
Remedy: Save your measurement data to a PC and then clear memory at 
test instrument by deleting the database or by importing an empty data-
base.
All
Delete measurement or database.
This prompt window asks you to confirm deletion.
SETUP
Data loss after restoring default settings.
Back up your measurement data to a PC before pressing the respective 
key.
This prompt window asks you to confirm deletion.
All
This error message appears when the database, i. e. the structure cre-
ated in the IZYTRONIQ, is too large for the device memory.
The database in the device memory is empty after database transfer has 
been interrupted.
Remedy: Reduce the database in IZYTRONIQ or send the database without 
measured vales (key Send structure) if measured values should already be 
available.
