1) Applications
DCV : Measures batteries and DC circuits.
ACV : Measures sine-wave AC voltage as lighting voltages.
2) Measuring ranges
DVC : 320mV
〜
1000V (5 ranges)
ACV : 3.2
〜
750V (4 ranges)
3) Measurement procedure (See fig4,5, page5)
①
Connect the test lead of the black plug to the COM input termi-
nal and the red plug to the "V" input terminal.
②
Set the function switch at "DCV" or "AVC" function.
③
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.
④
Read the value on the display.
⑤
After measurement, remove the red and black test pins from
the circuit measured.
●
Since this instrument employs the means value system for its
AC voltage measurement circuit, AC waveform other than sine
wave may cause error.

Resistance Measurement (
Ω
)
Never apply voltage to the input terminals.
1) Application
：
Resistance of resistors and circuits are measured.
2) Measuring ranges
：
320
Ω〜
30M
Ω
(6 range)
3) Measurement procedure
(See fig6, page6)
①
Connect the test lead of the black plug to the COM input termi-
nal and the red plug to the "
Ω
" input terminal.
②
Set the function switch at "
Ω
" function.
③
Apply the black and red test pin to measured circuit.
④
Read the value on the display.
⑤
After measurement, remove the red and black test pins from
the circuit measured.
●
If measurement is likely to be influenced by noise, shield the
object to measure with negative potential (test lead black) .
●
If a test pin is touched by a finger during measurement, measure-
ment will be influenced by the resistance in the human body to
result in measurement error.
●
The input terminals release voltage is about 1.3V.
