ELR 9000 HP Series
3.10.13.3 Other parameters
These parameters are available in both battery test modes, but the values are separately adjustable in each.
Parameter
Range
Description
Discharge voltage 0...Nominal value of U Variable voltage threshold to make the test stop when reached (is
connected to the battery voltage on the DC input of the load)
Discharge time
0...10 h
Maximum test time after which the test can stop automatically
Discharge capacity 0...99999 Ah
Maximum capacity to consume from the battery after which the test
can stop automatically
Action
NONE, SIGNAL, End
of test
Separately defines an action for parameters „Discharge time“ and
„Discharge capacity“. It determines what shall happen with the test
run once the adjusted values for those parameters are reached:
NONE
= No action, test will continue
SIGNAL
= Text “Time limit” will be displayed, test will continue
End of test
= The test will stop
Enable USB log-
ging
on/off
By setting the check mark, USB logging is enabled and will record
data on a properly formatted USB stick, if plugged in to the front USB
port. The recorded data differs from the USB log data recorded dur
-
ing “normal” USB logging in all other operation modes of the device.
Logging interval
100 ms - 1 s, 5 s, 10 s Writing interval for USB logging
3.10.13.4 Displayed values
During the test run, the display will show a set of values and status:
•
Actual battery voltage on the DC input in V
•
Actual discharge current in A
•
Actual power in W
•
Discharge voltage U
DV
in V
•
Consumed battery capacity in Ah
•
Consumed energy in Wh
•
Elapsed time in HH:MM:SS,MS
•
Regulation mode (CC, CP, CR)
3.10.13.5
Data recording (USB logging)
At the end of the configuration of both, static and dynamic mode, there is the option to enable the USB logging
feature. With an USB stick plugged and formatted as required (see ), the device can record data during the test
run directly to the stick and in the defined interval. Active USB logging is indicated in the display with a small disk
symbol. After the test has stopped, the recorded data will be available as text file in CSV format.
Log file format:
Static = Selected mode
Iset = Max. current
Pset = Max. power
Rset = Desired resistance
DV = Discharge voltage
DT = Discharge time
DC = Discharge capacity
U/I/Pactual = Actual values
Ah = Consumed battery capacity
Wh = Consumed energy
Regardless the setting for the recording interval, the values “Ah” and “Wh” are only calculated
by the device once per second. When using an interval setting of < 1 s, several identical values
of Ah and Wh are written into the CSV.
