5.10.1 Test Lead Current Measurements (A, mA, and µA)
1.
For test lead measurements (A, mA, and µA), set the function switch to the
or
position.
2.
Insert the black probe lead into the negative COM terminal and the red probe
lead into one of the following positive terminals:
•
A
for high current measurements.
•
mA
for lower current measurements.
•
µA
for micro-amp measurements.
3.
Use the
button to select AC or DC measurement.
•
The
indicator shows for AC measurements.
•
The
indicator shows for DC measurements.
4.
Connect the probe leads in series with the part in accordance with Figure 5.7
and Fig. 5-
8 for ‘A’ measurements, Fig. 5
-9 for mA measurements, or Fig. 5-10
for µA measurements.
5.
Read the current and frequency values on the display (note that the frequency
function is not available for the µA function). To display only the Frequency,
navigate to the
Hz
icon and enable (or disable) the mode by pressing
