Measuring DC Current
1.
Set the function switch to "
2.
Set the range switch to the " 200mA " range position.
3.
Turn off power to the circuit to be tested. Then discharge all capacitors.
Break the circuit path to be tested, then connect the test leads in series with the circuit.
4.
5.
Turn on power to the circuit, then read the reading on the display. The polarity of the red test lead
connection will be indicated as well.
Measuring Resistance
1.
Set the function switch to "
2.
Set the range switch to desired resistance measuring range position.
3.
Connect the test leads across the object to be measured.
4.
Read the reading on the display.
Note:
1.
For measurements > 1MΩ, the meter may take a few seconds to stabilize reading. This is normal
for high resistance measurements.
2.
When the test leads are in open circuit state, " 1 " will be displayed as an overrange indication.
3.
Before measurement, disconnect all power to the circuit to be tested and discharge all
capacitors thoroughly.
