PLZ2004WB/PLZ2004WHB 9
Calibration
The booster is shipped from the factory after carrying out a strict
calibration. However, to maintain the performance, periodic
calibration is recommended.
Calibrate the master unit and the boosters as a single electronic load
in the same manner as when you calibrate the master unit alone.
For details, see "Calibration" in the PLZ1004W/PLZ1004WH User's
Manual.
For calibration, use shunt resistors and a regulated DC power supply
that match the product's current capacity.

Specifications
Electrical Specifications
Unless specified otherwise, the specifications are for the following
settings and conditions.
•
Warm-up period: 30 minutes (with current flowing)
•
Ambient temperature: 23 ºC 5 ºC
•
TYP: These are typical values that are representative of situations
where the PLZ2004WB/PLZ2004WHB operates in an environment
with an ambient temperature of 23 ºC. These values do not
guarantee the performance of the PLZ2004WB/PLZ2004WHB.
•
% of set denotes % of the input voltage or input current setting.
•
% of f.s denotes % of the rated input voltage, rated input current or
rated input power.
•
% of reading denotes % of the input voltage or input current reading.

Minimum voltage at which the current starts flowing to the PLZ2004WB is approx.
0.3 V. The PLZ2004WB detects no signal at an input voltage less than or equal to
approx. 0.3 V and an input current less than or equal to approx. 1 % of the range
rating. If the input voltage is gradually increased from 0 V, no current will flow until
0.3 V is exceeded. Once a current greater than or equal to 1 % of the range rating
starts flowing, the current can flow at voltages less than equal to 0.3 V.

Condition in which the booster is connected to the master unit.
