Viewing, Editing, Transferring and Evaluat-
ing Measured Values
Up to 300,000 data records can be stored to the instrument.
Measured values and measurement series stored to internal mem-
ory at the battery tester can be viewed and edited directly at the
instrument. Brief measured value evaluations can also be viewed
at the instrument. We recommend this method for a quick, initial
visual assessment on site.
Transfer the measurement data to BT PRO Manager PC software
for storage and further evaluation.
You can also save a backup copy of the data on a PC.
This section describes how to view and edit measured values at
the instrument, and how to make data backups. Measurement
data evaluation is described in section on ““BT PRO Manager” PC
Software”
11.1
Viewing Measured Values / Measured Value Details at
the Instrument
Stored measured values, including measured value details, can be
viewed directly at the instrument.
1. Switch the battery tester on
2. Press the
OK

The detail view is displayed. The display differs depending on
the selected measurement
15. If there are
several measurements per measurement function (e.g. in the
case of a measurement series), you can scroll amongst the
measured values in the detail view using the
▼ ▲
keys.
Note
Normally, the measured values are displayed in black.
However, if a limit value is violated, the measured value is
displayed with a light-colored font and a black background
for emphasis.
11.2
Viewing Measured Value Evaluations at the Instrument
The battery tester automatically determines the sum, the mean
value and the smallest and largest measured values for all stored
measured values of a measurement series. You can view this brief
evaluation at the instrument.
1. Switch the battery tester on
2. Press the
OK
key.
The
main menu
appears.
3. Select
DATA MENU
from the
main menu
using the

7. Select the measurement you want to view using the
▼ ▲
keys.
8. Press the
OK
key repeatedly until the display appears with the
calculated values associated with the respective measure-
ment.
The measured value evaluation is displayed
15. If several measured values were ascertained during a sin-
gle measurement, you can scroll amongst the values displayed
in the evaluation using the
▼ ▲
keys.
After running through a full display cycle with the
▼ ▲
keys,
the display is automatically switched back to the higher-level
SHOW DATA
menu.
11.3
Excluding a Measurement from Transmission
(deactivate measurement)
If you’ve performed and saved a measurement that you don’t
want to take into account, you can subsequently deactivate it.
Deactivated measurements remain in memory at the battery tester,
but aren’t transferred during data transmission and are thus
excluded from evaluation.
1. Switch the battery tester on
2. Press the
OK
key.
The
main menu
appears.
3. Select
DATA MENU
from the
main menu
using the
▼ ▲
keys.
The
DATA MENU
menu is displayed.
4. Select
SHOW DATA
using the
▼ ▲
keys.
–
Press the
OK
key.
The menu for viewing the measurements is displayed
5. Select the measurement you want to deactivate using the
▼ ▲
keys.
6. Press and hold the
FUNCTION
key until you hear a brief acoustic
signal.
The number of blocks changes to “XXXXX”.
The measurement is deactivated.
11.4
Deleting Measured Values
Measurement data stored at the battery tester must be transferred
to an external PC for data evaluation and storage.
After successful transmission, the measurement data in the bat-
tery tester can be deleted so that sufficient memory space is once
again available for future measurements.
Note
All measurement data are deleted. Individual measure-
ments cannot be deleted separately.
1. Switch the battery tester on
2. Press the
OK
key.
The
main menu
appears.
3. Select
DATA MENU
from the
main menu
using the
▼ ▲
keys.
4. Press the
OK
key.
The
DATA MENU
menu is displayed.
5. Select
CLEAR DATA
using the
▼ ▲
keys.
6. Press the
OK
key.
The
DO YOU REALLY WANT TO DELETE?
prompt appears.
7. Press the
OK
key.
Note
Press the
FUNCTION
key in order to abort deletion.
All measured values stored at the battery tester are irretrievably
deleted.
11.5
Saving Measured Values to a PC (data backup)
We recommend backing up measurement data to a PC or other
external storage medium at regular intervals. Any possible loss of
data can be prevented in this way.
When measurement data is transferred to BT PRO Manager soft-
ware, an additional CSV file which contains the measurement data
is automatically saved to the PC
If you’re not using BT PRO Manager, you can transfer the mea-
surement data as a CSV file from the battery tester to a PC for
backup via a Bluetooth
®
connection.
In either case, the file is saved to the PC and can be transferred to
another medium or edited with a text editor.
