(5) Voltmeter Selector Switch
Positions:
Off:
There are two off positions on the voltmeter selector switch. One at the full clockwise
position and one at the full counter-clockwise position of the switch.
In either off position the voltmeter will not display any voltage.
L1-L2:
In the L1-L2 position the voltmeter will display the phase voltage between L1 and L2.
L2-L3:
In the L2-L3 position the voltmeter will display the phase voltage between L2 and L3.
L3-L1:
In the L3-L1 position the voltmeter will display the phase voltage between L3 and L1.
(6) Ammeter Selector Switch
Positions:
Off:
There are two off positions on the ammeter selector switch. One at the full clockwise
position and one at the full counter-clockwise position of the switch. In either off position
the ammeter will not display any amps.
This switch must be in the L1 or L3 position to read single phase current.
L1:
In the L1 position the ammeter indicates the 3-Phase amps for L1 and single-Phase amps
for L1.
L2:
In the L2 position the ammeter indicated the 3-Phase amps for L2.
L3:
In the L3 position the ammeter indicates the 3-Phase amps for L3 and single-Phase amps
for L3.
The voltmeter selector switch is a 5 position switch located on the
control panel to the left of the voltmeter.
The voltmeter selector switch selects which phase voltage is displayed
on the voltmeter.
The ammeter selector switch is a 5 position switch located on the
control panel to the left of the ammeter.
The ammeter selector switch selects which phase current is displayed
on the ammeter.
