AC Voltage Measurement ( )
DC Voltage Measurement ( )
Measuring range: 2V-600V (4 ranges, auto-ranging)
1.Set the function switch knob on
2.Plug the black test lead into COM terminal and the red
one into terminal
3.Connect the test leads to the
cir uit under test and then
read the value when
it stabilizes
4.The meter will choose
the appropriate range to
measure automatically
5.When measurement finished,
set the function switch knob
n OFF position to turn off
he meter.
Measuring range: 200mV-600V (5 ranges, auto-ranging)
1.Set the function switch knob on
2.Plug the black test lead into COM terminal and the red
one into terminal
3.Connect the test leads to the
circuit under test and then
read the value when it
stabilizes
4.The meter will choose the
appropriate range to measure
utomatically
6.When measurement finished,

Measuring range: 200 -20M (6 ranges, auto-ranging)
1.Set the function switch knob on
2.Plug the black test lead into COM terminal and the
red one into terminal
3.Connect the test leads to the circuit under test and
then read the value when it stabilizes
4.The meter will choose the appropriate range to
measure automatically
5.When measurement finished, set the function switch
knob on OFF position to turn off the meter.
: Before undergoing resistance measurement,
firstly switch off the power to the circuit under
test and fully discharge the capacitor.
