NOTE
2.4.5 Voltage (Frequency)
Automatic frequency detection (AUTO), 50 Hz fixed, or
60 Hz fixed can be selected. In cases where the input
fluctuates significantly, the indicated value will stabilize
when 50 Hz or 60 Hz fixed is selected. For how to select,
see the setup of measurement line frequency in SETUP
mode. (For details, see 2.9, "SETUP Function.")
There is a possibility to fluctuate 2 or 20 counts at the peak
value display when the input becomes big.
Some special frequencies can't be measured, such as
those of inverters.
1. Press the
U/
key to activate voltage display
mode. In voltage display mode, an effective value
appears on Display 1, peak-hold value on Display 2,
and frequency on Display 3.
2. Connect the voltage cord to the instrument, then
connect the red cord, yellow cord, and black cord to
the circuit under measurement.
3. Switch between Auto Range and Manual Range, as
needed. For details, see 2.3, "Range Setup."
4. Pressing the U/ key in voltage display mode
resets the peak-hold value.
Select the 1
φ
P meter, 1
φ
PF meter, or 3
φ
PF meter.
The instrument does not display polarities in a peak
measurement.
The peak hold value will not vary, unless a large value is
entered in the instrument. If the auto power-off function is
effective, the instrument will be shut down in about ten
minutes, causing the data to be lost.
(See 2.11, "Auto Power-Off Function.") One way to
prevent data from being lost is to disable the auto power-
off function (see 2.9, "SETUP Function") or to use the
recording function.
