AC/DC Voltage Measurements 

CAUTION:  Do not measure voltages higher than 300V. Damage 
may occur to the meter. 

1.

 

Set the function switch to the correct AC/DC voltage range. 

2.

 

Insert the black test lead into the COM input and the red 
test lead into the VmAΩ input. 

3.

 

For DC, touch the black test lead to the negative side of the 
circuit under test and touch the red test lead to the positive 
side. For AC, the test lead polarity is not a factor. 

4.

 

For DC only, if the pointer needle deflects to the left side of 
the scale, reverse the test leads.

DC mA Current Measurements 

1.

 

Set the function switch to the correct mA DC range. 

2.

 

Remove power to the circuit under test and open the circuit 
at the point to be measured. 

3.

 

Insert black test lead into the COM input and red test lead 
into the VmAΩ input. 

4.

 

Touch the black test lead to the negative side of the circuit 
and the red test lead to the positive side. 

5.

 

Apply power to the circuit.

If the needle deflects to the left, reverse the test leads.
