3. Partial cell configuration
This configuration may be used, if a certain part of a battery or fuel
cell stack has to be investigated.

4 V / 12 V
The potential will be indicated as negative in EL.
The measured current must be positive I

Depending on the type of the reference electrode the measured
potential may be different from the real potential at the reference
electrode site. The real potential can be calculated from the meas-
ured potential by subtracting the potential of the reference elec-
trode.
4. Applications with an additional power supply
This configuration may be used if the voltage
drop on the power lines is too high to reach
the high-current test conditions. In addition it
allows experiments on passive objects and
batteries under charging conditions and elec-
trolysis cell
Built-in buffer amplifier
The built-in buffer amplifier may be used to increase the potential range of the
EL
up to +/-12 V. To
select the buffer amplifier select the corresponding voltage range (±4V / ±12V) at the check cell
connection page.
