Ac Vo Ltag E M E A S U R E M E N T - SW-Stahl 32230L Mode D'emploi

A . D C VO LTAG E M E A S U R E M E N T
1.
Connect the red test lead to the "V.Ω.mA" jack and the black lead to the "COM" jack.
2.
Set rotary switch at desired DCV position. If the voltage to be measured is not known befo-
rehand, set range switch at the highest range position and then reduce it until satisfactory
resolution is obtained.
3.
Connect test leads across the source or load being measured.
4.
Read voltage value on the LCD display along with the polarity of the red lead connection.
B . D C C U R R E N T M E A S U R E M E N T
1.
Connect the red test lead to the "V.Ω.mA" jack and the black test lead to "COM" jack.
(For measurements between 200mA and 10A, remove red lead to"10A" jack.)
2.
Set the rotary switch at desired DCA position.
3.
Open the circuit in which the current is to be measured, and connect test leads in series with the
circuit.
4.
Read current value on LCD display along with the polarity of red lead connection.
C . AC VO LTAG E M E A S U R E M E N T
1.
Connect the red test lead to "V.Ω. mA" jack and the black test lead to the "COM" jack.
2.
Set the rotary switch at desired ACV position.
3.
Connect test leads across the source or load being measured.
4.
Read voltage value on the LCD display.
D . R E S I S TA N C E M E A S U R E M E N T
1.
Connect the red test lead to "V. Ω. mA" jack and black test lead to the "COM" jack.
(The polarity of red lead is positive "+".)
2.
Set the rotary switch at desired "Ω" range position.
3.
Connect test leads across the resistor to be measured and read LCD display.
4.
If the resistance being measured is connected to a circuit, turn off power and discharge all
capacitors before applying test probes.
