(Max. rated input voltage: 10 V dc/ac)
・
DC voltage (m ) measurement
・
DC Voltage (m )/AC Voltage(m
) simultaneous measurement
・
DC+AC Voltage (m )/AC Voltage (m
) simultaneous measurement
・
Logic-level frequency (
) measurement
・
Duty cycle (
D%) measurement
1. Do not apply any input signal exceeding the max. rated input voltage.
2. Do not switch the function selector while measuring.
3. Keep your fingers behind the finger guards of the test leads while
measurement.
WARNING
1) What to measure
・
m
(DC voltage): DC circuit voltage lower than 500 mV
・
m
/m (DC voltage component/AC voltage component)
・
m /m (DC/AC superimposed signal voltage/AC voltage
component)
・
(Logic level frequency): 3 V, 5 V logic circuit frequency
・
D%(Duty cycle): Logic level signal duty cycle (Square wave)
2) Measuring ranges
・
m , m /m , m /m : 500.00 mV (fixed)
・
m
(500000-count display mode): 500.000 mV (fixed)
・
: Auto ranging, 5.000 Hz to 1.000 MHz (Square wave)
・
D%: 0.1 % to 199.9 % (Square wave 5 Hz to 500 kHz)
3) Measuring procedure
①
Connect the red plug of the test lead to the VHz measuring
terminal and the black one to the COM terminal.
②
Set the function selector to
.
③
Press the SELECT button to select a function you want to
perform.
④
Apply the test pins (Red and Black) to the object to measure.
⑤
Read the display.
