AC Voltage Measurements
Measure AC conductors carrying up to 750 VAC, 45-450 Hz.
Turn the Range Selector Switch to 750 ACV setting.
Always start with the highest range if the voltage is unknown.
Plug the red lead into the VOmA (Center) Jack. Plug the black lead into the COM (Bottom) Jack. Switch the Multimeter ON.
Carefully touch the exposed conductors with the tips of the probes to measure the voltage (not amperes) .
Read measurement.
If the voltage is less than 200 volts, set the Range Selector Switch to the lower range.
When testing is complete, remove Test Leads and store with multimeter.
1 .
2.
DC Voltage Measurements
Measure DC conductors carrying up . to 1000 VDC.
Turn the Range Selector Switch to 1000 DCV setting.
Follow the directions above under "AC Voltage Measurements", only use the DC settings instead.

Turn the Range Selector Switch to the 10A position.
Always start with the highest range if the amperage is _unknown .
Plug the red lead into the 1 OA (Top) Jack. Plug the black lead into the COM
(Bottom) Ja ck. Switch the Multimeter ON.
Carefully touch the exposed conductors with the tips of the probes to measure the amperage.
Note: Amperage is always tested in series with the circuit under test.
4.
5.
Read measurement.
If the reading is less than .2AMPs, switch the red lead to the VOmA(Center)
Jack and set the Range Selector Switch to the 200 mA setting.
When testing is complete, remove Test Leads and store with multimeter.
Resistance Measurements
Measure circuit resistance up to 2000K Ohms.
WARNING: NEVER measure resistance on a circuit with voltage running through it.

Turn the Range Selector Swit ch to the 200 mA position.
Plug the red Test Lead into the VOmA (Center) Jack. Plug the black Test
Lead into the Com (Bottom) Jack. Switch the Multimeter ON.
Short the Test Leads together. The meter should read "O" Ohms.
Touch the exposed conductors with theJips of the Test Leads.
4. Read measurement.
If the reading is "1", set the Range Selector Sw i tch to the next higher Ohm
(0) position .

2.
Transistor (hFE) Measurements
Test transistors to ensure proper function.
Turn the Range Selector Switch to the hFE position.
Switch the Mul ti meter ON .
Insert the transistor pins into the appropriate hFE jack (NPN or PNP) according to the EBC (Emitter, Base, Collector) sequence.
The meter will show the approximate hFE value. 3.
