2. Switch of main engine
Press
POWER
to start the engine, and LCD displays. After
the normal startup, the main engine will enter test receiving mode
(see the picture above). The primary current is the testing data of
high-voltage terminal while the secondary current the low-voltage.
In case that signals are detected in both primary and secondary
circuits, the main engine will show the transformation ratios on the
basis of secondary circuit bearing current 5A, and indicate phase.
If in phase
，
it shows "
⊕
" symbol
；
if out of phase, it shows "
Θ "
symbol, if the phase can
’t be properly identified, it shows "Er"
symbol.
If transformation ratio is too high, which means that the current
value in the primary circuit is large while it in the secondary is small,
the ratio surpasses 1000,000, i.e. “x.xxxK6” (x.xxx×10
6
) is
displayed,
the numeral value behind “K” means the power of 10. Of
course, this phenomenon will not occur in the normal operational
circuit.
In data search mode, press
POWER
key and shift the cursor to
“return”, return to the test mode by pressing the
HOLD
key, power
off by pressing the
POWER
key.
