condition keeps the external battery from discharging while the output is
off.
CAUTION If using the I-Source to charge and/or discharge batteries, the
following precautions must be observed. Failure to observe
these precautions could result in damage to the SourceMeter
that is not covered by the warranty.
Make sure the external voltage NEVER exceeds the voltage
compliance setting of the I-Source. This will cause excessive
current to be drawn from the external battery or source.
Make sure the output off state of the I-Source is set for HIGH-
IMPEDANCE. This setting opens the output relay when the
OUTPUT is turned OFF. With the NORMAL output off state
selected, turning the output off sets voltage compliance to
zero. This 0V compliance condition will cause excessive cur
-
rent to be drawn from the external battery or source. See
Section 13, “Front panel output configuration” to select the
high-impedance output off state.
