6.6. Measuring AC Voltage

Insert the black test lead banana to the COM jack and red test lead 
banana to the “V / Hz% / 

Ω

 

/

 

CAP

°C“ jack.

Set the function switch to the AC ranges to be used and connect 
test leads across the source or load under measurement.

Read the LCD display. The polarity of the red connection will be 
indicated when making an AC measurement.

Press the Hz% button to indicate “Hz”.

Read the frequency on the display.

Press the Hz% button again to indicate “%”.

Read the % of duty cycle on the display.

6.7. Measuring DC Current

Insert the black test lead banana plug into the negative COM jack. 
and the red test lead banana plug into the “uA/mA” or “10A” jack.

For current measurements up to 4000uA DC, set the function 
switch to the µA position and insert the red test lead banana plug 
into the uA/mA jack.

For current measurements up to 10A DC, set the function switch to 
the yellow 10A position and insert the red test lead banana plug 
into the 10A jack.

Press the MODE button to indicate “DC” on the display.

Remove power from the circuit under test, then open up the circuit 
at the point where you wish to measure current.

Touch the black test probe tip to the negative side of the circuit. 

Touch the red test probe tip to the positive side of the circuit.

Apply power to the circuit.

Read the current in the display.

6.8. Measuring AC Current

Insert the black test lead banana plug into the negative COM jack. 
and the red test lead banana plug into the “uA/mA” or “10A” jack.

For current measurements up to 4000uA AC, set the function 
switch to the uA position and insert the red test lead banana plug 
into the uA/mA jack.

For current measurements up to 400mA AC, set the function switch 
to the mA position and insert the red test lead banana plug into the 
uA/mA jack.
