3.
Caution: The maximum input current is 200 mA, or 10 A
depending upon the jack used. Excessive current will blow the
fuse which must be replaced.
4.
Replace the blown fuse only with a fuse with the same ratings
and dimensions.
6.5. Resistance Measurement
1.
Connect the black test lead to the COM jack and the red test
lead to the V/ /-mA- jack. (Note: The polarity of the red test
lead is "+")
2.
Set the function switch to the
the test leads across the resistance under measurement.
Note:
1.
If the resistance value being measured exceeds the maximum
voltage of the range selected, an over-range indication will be
displayed ("1"). Select a higher range. For resistance approx. 1
M
and above, the meter may take a few seconds to stabilize.
This is normal for high resistance readings.
2.
When the input is not connected, i. e. at open circuit, the
figure "1" will be displayed for the overrange condition.
3.
When checking in-circuit resistance, be sure the circuit under
test has all power removed and that all capacitors are fully
discharged.
6.6. Diode Measurement
1.
Connect the black test lead to the COM jack and the red test
lead to the V/ /-mA-jack. (Note: the polarity of the red test lad
is "+")
2.
Set the function switch to the
leads across the diode under measurement.
