001.xxx Error [001] No valid CT software!
Reason: No valid software in the device Flash memory or incorrect checksum.
Solution: Insert a Compact Flash card with valid software ( CTAnalyzer.bin ) in the
Omicron directory and switch the CT Analyzer off and on again.
002.xxx Error [002] Can't open file!
Reason: The firmware cannot read the file CTAnalyzer.bin from the Compact Flash
card since the CF card or the file is missing.
Solution: Insert a Compact Flash card with valid software ( CTAnalyzer.bin ) in the
Omicron directory and switch the CT Analyzer off and on again.
003.xxx Error [003] Download error!
Reason: The downloaded software is corrupt.
Solution: Insert a Compact Flash card with valid software ( CTAnalyzer.bin ) in the
Omicron directory and switch the CT Analyzer off and on again.
100.xxx Warning [100.xxx] CT resistance > 3000 Ohms.
Reason: The resistance measured during primary or secondary winding resistance
measurement is > 3000
Ω
.
Solution: The test cannot be continued. Check the connections to the CT. If the
connections are ok, the CT resistance is > 3000
Ω
. Such CTs cannot be tested
using the CT Analyzer .
101.xxx Warning [101.xxx] Timeout during measurement. No constant winding resistance can
be determined within 10 sec.
Reason: The CT Analyzer cannot determine a constant winding resistance within
10sec. during primary or secondary winding resistance measurement.
Solution: The test cannot be continued. Check the connections to the CT.
110.xxx Warning [110.xxx] The impedance of the CT is too high.
Reason: The impedance of the CT or the load is too high to reach the minimum toggle
frequency of 0.2Hz / 0.8Hz.
Solution: The test cannot be continued. Check the connections to the CT. If the
connections are ok, it is not possible to test this CT due to its too high
inductance.
111.xxx Warning [111.xxx] Inductance of load too low.
Reason: Measurement frequency is too high and cannot be decreased because of too
low CT inductance.
Solution: The test cannot be continued. Check the connections to the CT. If the
connections are ok, it is not possible to test this CT due to its too low
inductance.
112.xxx Warning [112.xxx] Measurement error, reduce noise level.
Reason: It is not possible to obtain stable measurement results due to incorrect wiring,
wiring short-circuit, connected load or external interferences.
Solution: Check the wiring. The primary side of the CT must not be short-circuited.
Disconnect the primary side of the CT from the transmission lines, connect one
primary side terminal to PE and open the other one. Use the delivered original
coax cables for measurement (see section 2.7.2 ”Noise Reduction
Techniques” on page 43). Make sure that no burden is connected to the
secondary side of the CT. This error may also indicate a winding short circuit
of the CT.
