5-2 Voltage, Hz/DUTY measurement
WARNING
1. Never apply an input signal exceeding the maximum rating input value.
2. Be sure to disconnect the test pins from the circuit when changing
the function.
3. Always keep your fingers behind the finger guards on the probe
when making measurements.
5-2-1 Voltage Measurement (DCV,ACV)
Maximum rating input value DC/AC 500V
1) Applications
DCV
: Measures batteries and DC circuits.
ACV
〜
: Measures sine-wave AC voltage as lighting voltages.
2) Measurement procedure
①
Set the function switch
DCV
or
ACV
function.
②
Apply the black test pin
to the negative potential
side of the circuit to measure
and the red test pin to the
positive potential side.
③
Read the value on the display.
④
After measurement, remove
the red and black test pins from
the circuit measured.
●
The display fluctuates when
the test leads are removed. This is not malfunction.
●
Since this instrument employs the means value system for its AC
voltage measurement circuit,
AC waveform other than sine wave
may cause error.
●
In the AC4V ranges a figure of about 3
〜
9 conuts will stay on even if
no input signal is present.
●
The accuracy guaranteed frequency range is 40Hz to 400Hz.
