DC Voltage Measurements

Measure DC conductors carrying up to 250 VDC.
1.
Turn the Range Selector Switch
to 250 DCV setting.

DC Current Measurements

Measure DC conductors carrying up to 5 amperes.
1.
Turn the Range Selector Switch
to the 5A position.
2.
Always start with the highest range
if the amperage is unknown.
3.
Plug the red lead into the 5ADC (Top)
Jack. Plug the black lead into the COM
(Bottom) Jack. Switch the Multimeter ON.
4.
Carefully touch the exposed
conductors with the tips of the probes
to measure the amperage.

Resistance Measurements

Measure circuit resistance up to 2000K Ohms.
1.
Warning: Never measure resistance on a
circuit with voltage running through it.
2.
Turn the Range Selector Switch
to the 200 Ω position.
3.
Plug the red Test Lead into the
VΩmA (Center) Jack. Plug the black
Test Lead into the Com (Bottom)
Jack. Switch the Multimeter ON.
Transistor (hFE) Measurements
Test transistors to ensure proper function.
1.
Turn the Range Selector Switch
to the hFE position.
2.
Switch the Multimeter ON.
3.
Insert the transistor pins into the appropriate
hFE jack (NPN or PNP) according to the
EBC (Emitter, Base, Collector) sequence.

For technical questions, please call 1-888-866-5797.
2.
Follow the directions above under
"AC Voltage Measurements", only
use the DC settings instead.
Note: Amperage is always tested in
series with the circuit under test.
5.
Read measurement.
6.
If the reading is less than .2 AMPs,
switch the red lead to the VΩmA (Center)
Jack and set the Range Selector
Switch to the 200 mA setting.
7.
When testing is complete, remove Test
Leads and store with multimeter.
4.
Short the Test Leads together. The
meter should read "0" Ohms.
5.
Touch the exposed conductors
with the tips of the Test Leads.
6.
Read measurement.
7.
If the reading is "1", set the Range Selector
Switch to the next higher Ohm (Ω) position.
4.
The meter will show the
approximate hFE value.
