AC Voltage Measurements
Measure AC voltages up to 500 V.
1. Turn the Range Selector Switch to 500 ACV.
Always start with the highest range if the voltage is unknown.
2. Follow the directions on the previous page under
DC Voltage Measurements
(except for the polarity directions, they are unnecessary with AC).
DC Current Measurements
Measure DC conductors carrying up to 250 mA (.25 A).
1. Turn the Range Selector Switch to the 250 DCmA position. Plug the red lead
into the +Jack. Plug the black lead into the -Jack.
2. First, disconnect the power to the circuit to be tested. Disconnect the
ground side of the circuit and connect the meter to each disconnected end (in
series). Turn the circuit’s power on. If the pointer moves the wrong way, re-
verse the connection.
3. If the Amperage is less than 25 mA (.025 A), first disconnect power to the
circuit, set the Range Selector to the 50 DCmA range, and reconnect power.
If the Amperage is less than .25 mA, first disconnect power to the circuit,
set the Range Selector to the .5 DCmA range, and reconnect power.
4. When testing is complete, first disconnect power to the circuit, switch the
meter to OFF, remove the Test Leads, reconnect the circuit’s ground side, and
store the leads and meter in the provided case.
Resistance (Ohm) Measurements
Circuit resistance is measured at meter reading times 1,000.
Note: Testing resistance should ONLY be done with the power to the circuit
disconnected. Test to make sure no voltage is present first. If voltage is
applied while testing, disconnect the tester immediately, otherwise the
tester may be damaged.
1. Turn the Range Selector Switch to the Ohm testing position (X1K).
2. Plug the red lead into the +Jack. Plug the black lead into the -Jack.
3. Short the Test Leads together. The meter should read “0” Ohms.
4. If the meter does not read “0” Ohms, the ohmmeter needs to be calibrated to
enable accurate measurements. With the test leads held together, adjust the
Ohm Zero Adjust Knob until the meter’s pointer aligns on “0”. If this is not
possible, the battery may need to be replaced-see

5. Touch the exposed conductors with the tips of the Test Leads. If, by chance, a
voltage is present, the meter may be damaged or destroyed. Immediately
remove the Test Leads from the conductors.
