Object of
measurement
Select from among independent between channels
(UNIQUE), one-phase two-wire (2 systems), one-phase
three-wire, or three-phase three-wire.
Input settings
UNIQUE
Other settings
Select from among "voltage," "9018," "9132," "3283,"
"3284," "3285," and "9322."
It is possible to set odd channels to voltage and even
channels to current. (When measuring power, it is
necessary either to select input type "9018" or "9132," or
else to select input type "voltage" and then use a clamp-
on probe with good phase precision and apply current
scaling.)
Measurement range
1. Voltage : 5, 10, 20, 50, 100, 200, 500 mVr/DIV
1, 2, 5, 10, 20, 50 Vr/DIV
2. 9018 : 10, 20, 50, 100, 200, 500 Ar
3. 9132 : 20, 50, 100, 200, 500, 1000 Ar
4. 3283 : 10 m, 100 m, 1, 10, 200 Ar
5. 3284 : 20, 200 Ar
6. 3285 : 200, 2000 Ar
7. 9322 : 50, 100 Vr
