Measured Value Storage with Deviating Electrical Circuit Parameter
The electrical circuit parameter selected by yourself at the test instrument does not
coincide with the parameter entered under object data in the structure.
Example: Residual operating current is specified as 10 mA in the database, but you
have performed measurement with 100 mA. If you want to perform all future mea-
surements with 100 mA, the value in the database has to be changed by acknowl-
edging with the key. The measured value is documented and the new param-
eter is accepted.
If you want to leave the parameter in the database unchanged, press the key.
The measured value and the changed parameter are only documented in this case.
Err39 All (page 39) Please enter a designation (alphanumeric).
Err40 All
Operation with a Barcode Scanner
Error message when the “EDIT” entry field is opened and rechargeable battery
voltage is less than 8.0 V. Output voltage is generally switched off during barcode
scanner operation if U is less than 8.0 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 batteries must be replaced
towards the end of their service life.
Err41
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.
Err42 All
Operation with a Barcode Scanner
Barcode not recognized, incorrect syntax
Err43 All
Data cannot be entered at this location within the structure.
Remedy: observe profile for preselected PC software (see SETUP menu).
Err44 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 4.5).
Err45 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 database.
Err46 All
Delete measurement or database.
This prompt window asks you to confirm deletion.
Err47 SETUP
Data loss after changing language or profile,
or 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.
Err48 All
This error message appears if the database, i.e. the structure created in ETC, is too
large for the instrument’s internal memory.
The database in the instrument’s internal memory is empty after database transfer
has been interrupted.
Remedy: reduce the size of the database in ETC or transfer the database without
measured values (Transmit Structure key), if measured values already exist.
