Features
❍
Polarity-specifi c integral function measures battery charging and discharging with one instrument
(positive, negative and total integral values)
❍
Operating time/Rate display function measures load operating status
(with settable threshold value)
❍
Polarity-specifi c peak current display function measures peak battery charge and discharge current with one instrument
❍
Repeat measurement and data storage function lets you easily conduct the same measurement up to 20 times and then save that
data in the unit's memory.
❍
Time-limited mean value display function shows the mean value within a specifi c integration time
(can be used in combination with
repeat measurement)
❍
External DC power capability enables long-term measurements under battery power

Convenient Repeat Measurement Function
Integral measurements during a specifi ed interval can be
repeated continuously up to 20 times.
Integral and numerical measurement data values
(maximum, minimum, mean and peak) plus operating
time and duty are stored in internal memory. Saved data
can be recalled and verifi ed at any time.
