2.5 Measuring Control Function
Load testing
: Can provide load power
up to the model’s rated power, test and display
stable state 3 phase voltage, current, active power, frequency, and working time of
generator sets.
Load/unload with one key:
Whether manual control or software control, user can preset
the power, then press load master button. Loading is according to preset power to avoid
load fluctuation during the power changing.

Intelligent control
: Through PC software, user can set automatic loads and display,
record, and manage testing data. User can also form curves, tables, and print reports.
Local meter display data:
Displays
3 phase voltage, current, active power, frequency, etc.
2.6 Software Function
Communication pattern
: The intelligent control uses a photoelectric isolated RS485
interface connected to PC with anti-interference technology to make system control
stable. Users can also use USB or RS232 through a converter.
