The
RTC Memory
test writes to and reads from the memory of the Real Time Clock. By checking the
consistency of the data read back, it indirectly checks the presence, operation and connections of the
Real Time Clock. Failing the test yields a
Warning
.
▪ Check Time and Date of the Instrument and reset it to the current Time and Date. Run the Self
Test again.
The
RTC Oscillator
test reads a test flag within the internal Real Time Clock. If the Oscillator has
failed since the last restart or since the last Self Test, a
Warning
appears.
a
This indicates that since the last restart or last Self Test any recorded events may have
an incorrect time and date stamp.
▪ Check Time and Date of the Instrument and reset it to the current Time and Date. Run the Self
Test again.
6.1.4. Battery
If "Battery" is selected, the following test routines will be performed:
The
Primary Battery Error
test will set an
Error
flag if the voltage level of the main battery sinks
below 10.5 VDC. This flag will be cleared again once the voltage level rises above 11.0 VDC.
a
With this Error flag set the Instrument is no longer able to record events reliably. Although this
is a severe error, recording/operation is not blocked by the GSR and AS instruments. However
the error information is, as always, indicated in the header of an occurring event for later
validation of the data. GCR instruments stop recording in case of this failure.
▪ Connect AC power to the Instrument to charge its main battery or replace the battery.
The
Primary Battery Warning
test will set a
Warning
flag if the voltage level of the main battery sinks
below 11.0 VDC. This flag will be cleared again once the voltage level rises above 11.5 VDC.
▪ Connect AC power to the Instrument to charge its main battery or replace the battery.
The
Back Up Battery
test will set a
Warning
flag as soon the voltage level of the Backup battery
sinks below 2.8 VDC.
a
With this Warning flag set the Instrument may no longer maintain the correct time and
may loose data within its internal memory when the unit is disconnected from the main
battery.
▪ Replace the Backup battery on the main board.
6.1.5. Memory
a
Only for GCR and GSR instruments.
a
The memory tests may be time consuming, depending on the amount of memory installed in
the instrument.
If "Memory" is selected, the following test routines will be performed:
The
Memory Full
test is an on-line test and monitors the amount of data memory used. After the data
occupy more than 90% of the memory available, a
Warning
appears. An
Error
is indicated when the
data memory has overflowed.
