3. If you are using the A terminal, set the rotary switch to
mA/A. If you are using the mA/μA terminal, set the
rotary switch to μA for currents below 6000 μA
(6 mA), or mA/A for currents above 6000 μA.
4. To measure dc current, press
A.
5. Break the circuit path to be tested. Touch the black
probe to the more negative side of the break; touch
the red probe to the more positive side of the break.
Reversing the leads will produce a negative reading,
but will not damage the Meter.
6. Turn on power to the circuit; then read the display. Be
sure to note the unit given at the right side of the
display (μA, mA, or A).
7. Turn off power to the circuit and discharge all high-
voltage capacitors. Remove the Meter and restore the
circuit to normal operation.
The following are some tips for measuring current:
• If the current reading is 0 and you are sure the Meter
is set up correctly, test the Meter's fuses as described
under "Testing the Fuses".
• A current Meter drops a small voltage across itself,
which might affect circuit operation. You can calculate
this burden voltage using the values listed in the
specifications in Table 14.
