Note!
The battery tester can also be switched off by pressing the Function key. The key must
be pressed and held for approximately 10 seconds to this end.
However, it’s preferable to switch the instrument off using the switch off function.
4.4 Getting Started
After switching the instrument on (11), the main menu appears at the display. This is the
central menu from which all other hierarchically subordinate menus and functions can be
accessed. All available functions can be selected via the ▼ and ▲ keys:
Various measurements can be performed with the battery tester:
Function Description
MEASUREMENT Available measuring functions
DATA Data management functions
SETTINGS Parameter settings for system, measurements and data transfer
INFO Information concerning firmware version, battery charge level and mem-
ory occupancy
SWITCH OFF Switch off the battery tester
Measurement Description
MULTIMETER DC and AC voltage measurements without storing measured values
TRICKLE CHARGE Periodic measurement of block voltages.
This measurement is used for quarterly recording of trickle charge volt-
age, for example in UPS systems.
DISCHARGING Multiple measurement of block voltages at short intervals during dis-
charging
CHARGING Multiple measurement of block voltages at short intervals during
charging
RESISTANCE Periodic measurement of the internal resistance of the blocks
TEMPERATURE Measurement of block temperature with an IR temperature sensor
CONNECTOR Measurement of voltage drop to determine connector loss between
blocks
INTERVAL U Measurement of the voltage of a battery in freely definable time intervals
(voltage curve)
INTERVAL U + I Measurement of the voltage and current of a battery at freely definable
time intervals (voltage and current curves)
Example: Recording of discharge current during discharging.
