determines what shall happen with the test if any of the adjusted limits is
reached:

SIGNAL = A text “Time limit” or “Ah limit” will be displayed on screen to
notify about reaching a limit, but the test will continue

on/o󰀨 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di󰀨ersfromtheUSBlogdatarecordedduring“normal”USB
logging in all other operation modes of the device.

3.11.16.6 Displayed values
During the test run, the display will show various values and statuses:
• Actual battery voltage on the DC terminal
• Discharge voltage U
DV
in V (only in discharge mode)
• Charge voltage in V (only in charge mode)
• Actual discharge or charge current
• Actual power
• Total battery capacity (charging & discharging)
• Total battery energy (charging & discharging)
• Elapsed time
• Regulation mode (CC, CP, CR, CV)

3.11.16.7 Data recording (USB logging)
AttheendofthecongurationofalltestmodesthereistheoptiontoenabletheUSBloggingfeature.Withan
USB stick plugged and formatted as required (see 1.9.6.5), the device can record data during the test run directly
tothestickandinthedenedinterval.ActiveUSBloggingisindicatedinthedisplaywithasmalldiskettesymbol.
Afterthetesthasstopped,therecordeddatawillbeavailableastextleinCSVformat.
Logleformatexamplefromstaticdischargemode:
Static = Selected test mode
Iset = Discharging current
Pset = Max. power
Rset = Desired resistance
DV = Discharge end voltage
DT = Discharge end time
DC = Discharge end capacity
U/I/Pactual = Actual values
Ah = Consumed battery capacity
Wh = Consumed energy
Time = Elapsed test time
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 log le.
