3. Choose a voltage range in accordance to the measured circuit.
Table 2- 3 Measurement Characteristics of AC Voltage
Ranges*
600mV, 6V, 60V, 600V, 750V
Input Protection
750Vrms on all ranges (HI terminal
）
Configurable
Range, Speed, Rel, Auto
NOTE*:
●
All the ranges can withstand a 10% value higher than the range maximum
except 750V.Manual and Auto are available on every range.
●
When inputting a value that is higher than 750V at the 750V Level,
“overload” will be displayed on the screen.
●
750V input protection exists on every range.
4. Set the relative value (Optional operation).
Press
[
Rel
]
to turn on or off the Relative math function. When it is on,
the reading displayed is a relative value which comes from the result of
actual measurement value minus the relative value that has been set.
The default relative value is the measurement value when the function is
Turned on. For details, please refer to “Maths Functions” in Chapter 2.
5. Read the measurement result.
Select required measurement rate (reading rate) by pressing [Speed] and
read the measurement result. Press
and then press
and
to get the frequency value measured from the input AC signal.
