The QL series provides multiple ranges for
increased current capability at lower voltages.
For the QL355, the main range offers 0 to 35 volts at up to 3
amps. The higher current range provides up to 5 amps for
voltages up to 15V.
The QL564 has a main range of 0 to 56 volts
at up to 2 amps. The higher current range provides up to 4 amps
for voltages up to 25V
On both models, a
further low current range provides an enhanced current setting
and measurement resolution of 0.1mA.
