WIDE position
If the circuit under test is originated from a high frequency generating
device (e.g. inverter, switching regulators, etc.) the switch should be set
to
"WIDE „position to measure the signal, which contains the frequency
from 40 Hz to 1 kHz. To verify the presence of high frequency signal,
compare measurement at "50/60 Hz" and "WIDE" position to see the
difference. If the reading is very different, it is certain that the high
frequency signals or harmonics present.
Relative Reading measurement
The "ZERO" button also can be used to make a relative measurement.
Once the button is pushed, the current reading is set to zero and the
"ZERO" symbol is displayed. All the subsequent measurement are
displayed as a relative value with respect to the value being zeroed.
Press the "ZERO" button for 2 seconds to return to normal mode.
Bar Graph
Bar graph has forty segments. It displays segments proportional to the actual
reading. Each segment represents one count.
