● Three-memory function and switching function
Individual set values can be stored in three memories [A], [B], and
[C] and can be recalled freely. For the C.C and C.R modes, the instru-
ments have a switching function that recalls these values from the
memories in the order [A], [B], [C], [A], [B], [C], .... and executes
them repeatedly.
● Soft-start function that suppresses output voltage distortion
The start-up time of the instruments can be changed in accordance
with the output-voltage rise time for the device being tested. This
allows them to conduct tests which more closely approximate real-
world conditions.
(Soft-start time: Selectable from 0.1, 1, 2, 5, 10, 20, 50, and 100 ms)
Note: In case of PLZ-3WH series, selectable from 0.5ms.
● Memory card that allows significantly improved operability
Data set from the front panel or through GPIB can be saved in the
optional memory card. Using this card, other sections such as pro-
duction and inspection lines can easily recall setup data and set up
current simulation data.

● Short-circuit function that allows instantaneous setting of the
maximum current
During operations in C.C or C.R mode, pressing the SHORT key al-
lows you to set either the maximum current value (in C.C mode) or
minimum resistance value (in C.R mode) of the range instantaneously,
without using the JOG or SHUTTLE key. In addition, when a large-
current relay or other element is connected to the external control
connector as shown below, if the voltage at the load terminals falls
below approximately 1.5 V, the load terminals will be in a short-cir-
cuit state. This allows the instruments to perform effectively at cur-
rents of 1.5 V or less during current-limiting drooping characteristic
tests of DC power supplies.

● Parallel operations that offer increased current and power
capacities
The PLZ-3W/3WH Series allow parallel connection of identical mod-
els in order to increase current and power capacities. In parallel op-
erations, a single master unit can control multiple slaves, such as set-
ting total current for all. Naturally, the total current is also displayed
on the monitors. A maximum of five instruments can be operated in
parallel.
