must be part of the circuit to be measured.
Read the value on the topmost DC scale. Note that full 10A measurement will register
as “10” on this scale, and not provide a full scale reading.
Important Note: Measurements in excess of 5A should not be done for periods in
excess of 20 seconds.
Set the range selector to .))) position (one position counterclockwise from the x1
OHMS scale).
Connect the red lead to the (+) VΩA input.
Connect the black lead to the (–) COM input.
Connect the test probes to the circuit or device to be tested.
The internal buzzer will sound when continuity exists between the two probes.
Note: The buzzer will sound when the circuit impedance is below 100Ω.
Important Note: Make sure that no voltage is present in the circuit to be measured,
including discharging of any associated capacitors. Even small voltage levels can
cause permanent damage if applied to the meter while in the OHMS range.
Set the range selector to proper Ω position
“Zero” the meter. This is accomplished by simultaneously depressing the 0Ω CAL. SW
button, and rotating the OHMS ADJUST control until the meter displays “0” ohms. If a
0Ω reading cannot be obtained, the meter batteries are low and should be replaced.
Connect the red lead to the (+) VΩA input.
Connect the black lead to the (–) COM input.
Connect the test probes to the circuit or device under test. Make certain not to touch
the metal probe tips with your fingers, as your body resistance will affect the reading.
Read the value on the OHM scale and multiply it by the multiple designated by the
range you have selected.
For best accuracy, select a range that will provide a meter reading closest to the
center of the scale.
To obtain accurate readings, perform the Zero meter function each time the OHMS
scale is changed.
Set the range selector to one of the ACV ranges.
Connect the red lead to the (+) VΩA input.
Connect the black lead to the (–) COM input.
When using the 12V range, read the measurement directly from the dB scale.
When using other scales, you must add the appropriate number of dB as noted on the
following table:
12V
30V
120V
300V
1000V
