6.
▪
I/30 , enables to make the settings at a reduced
current, only 1/30 of the real test current. The
settings are approximate and work best for linear
loads.
7.
▪
Current adjust knob
to set (adjust) the generated
current.
Adjustment is sensitive to the turning speed.
▪
OPERATE lamp indicates current generation
▪
Green, yellow and red LEDs indicate percentage of
current generated for a specific load.

METERS
V Voltmeter
A
Ammeter 2
For making the connections needed to measure a
voltage or a second current. This is useful when (for
example) you want to measure phase angles, polarity
or the turns ratio of a current transformer. You can
make your settings using the "V/A METER" menu
option in the
MENU block.
An indicator lamp lights up to indicate whether you
have activated the Voltmeter or the A-meter 2.
WARNING
