Phase Rotation - PCE Instruments Chauvin Arnoux C.A 704 Notice De Fonctionnement

Buzzer continuity
I For a resistance inferior to toughly 600W,
the buzzer operates and the measured
resistance value appears on the display (in kW).
Resistance measurement
Range Measurement range
0.001 kΩ to 1.999 kΩ
1,999 kΩ
Accidental voltage presence ( 1V AC or DC)
on the circuit to be tested.
I
If the device detects the presence of a
voltage the buzzer sounds continuously and
the red LED «Voltest» comes on.
Characteristics and field of use:
I
Protection : up to 600V rms (for 10s)

7. PHASE ROTATION

Always run a self-test before using your
multimeter.
Never use it if the self-test is incorrect.
I Check for phase presence on the three
phases to be tested for three phase system.
Phase Rotation Test:
I Bring the red contact tip of the to the first
phase and the black tip to second phase.
I Press the phase rotation button.
Result:
I If the phase rotation order is direct, LED L1
to L2 lights up.
I If the phase rotation order is indirect,
LED L1 to L3 lights up.
NB : The voltage detection is still active during
this test.
Characteristics and field of use:
I Voltage : 360V < U < 690V
I Frequency: 50Hz and 60Hz (± 5%)
