waveform signal over a certain period is shown. The value is
calculated as the square root of the mean (average) value of
the squared function of the signal.
EQ PEAK (equivalent peak value): This is the maximum
peak value based on the assumption that the RMS value is
for a sinusoidal wave.
It is calculated as RMS x 2= EQ PEAK
EQ P-P (equivalent peak-to-peak value): This is the
difference between the minimum and the maximum peak
value based on the assumption that the RMS value is for a
sinusoidal wave.
It is calculated as EQ PEAK x 2 = EQ P-P

The required matter is indicated before beginning measurement.
Always set the power to OFF before inserting batteries and
making any connections.
5-1 Power Supply
The meter can be powered by four IEC R6 (sizeAA) batteries
or by the optionalAC adapter VA-03 (for 100 to 240VAC).
Battery installation:
When the meter is in operation, press key to turn off the
meter.
Insert four IEC R6 (size AA) batteries with correct polarity
as follows.
Make sure that all four batteries are of the same type.
Do not mix different battery types or old and new batteries.
Prevention of battery fluid leakage:
1. When the battery power is low, replace the new battery
in order to avoid thefurther battery fluid leakage possibility.
2. When the meter will not be in use for the long period of
time, please remove the batteries out of meter to
prevent the possibility of battery fluid leakage damage.
