4. Phase Rotation
Line1
Line2
Line3
NOTE :
-
Connect the three phases of the power source as shown
above.
-
The test is only possible while the system frequency is
stable.
1. Plug the Black test lead into the COM terminal and the Red
test lead into the V-
Ω
terminal.
2. Set the rotary switch to the “ RST ” position.
3. Connect the Red test lead to the supposed phase 1, and the
Black test lead to the supposed phase 3.
a. If the voltage < 30V, it display will show “
Lo V
” ; if voltage
> 1000V, then it will show “
OL
V
”.
b. If the frequency is not 50 Hz or 60 Hz, then it will display
“
out. F
”.
c. If the voltage and frequency are normal, the display will
show “
L1
” for about 3 sec.
4. If the display shows “
L2
”, the BUZZER will sound twice.
Connect the Red test lead to the supposed phase 2 before
the “
L2
” has disappeared.
5. When “
L2
” has disappeared, the display will show the testing
result.
