1. Turn off power to the device under test and discharge all capacitors.
2. Set the Function/Range switch to the desired voltage type (AC or DC)
range.
3. Plug the black test lead into the COM jack on the DMM and connect
the test lead point to a grounded point (the reference point for mea-
surement of voltage).
4. Plug the red test lead into the V jack on the DMM and connect the test
lead point to the circuit where a voltage measurement is required.
Voltage is always measured in parallel across a test point.
5. Turn on power to the circuit/device to be measured and make the volt-
age measurement. Reduce the range setting if set too high until a sat-
isfactory reading is obtained.
6. After completing the measurement, turn off power to the circuit /
device under test, discharge all capacitors and disconnect the DMM
test leads.
1. Turn off power to the device under test and discharge all capacitors.
2. Set the Function/Range switch to the desired current range.
3. Plug the black test lead into the COM jack on the DMM and connect
the test return branch for the current to be measured.
4. Plug the red test lead into the 200mA current jack of the DM2.
Current measurements are always made with the meter in series with
the test branch. The circuit must be broken and the meter put in series
by placing the red test lead point to the test node for current.
5. Turn on power to the circuit/device under test and make the current
measurement. Reduce the range setting if set too high until a satisfac-
tory reading is obtained.
6. After completing the measurement, turn off power to the circuit/device
under test, discharge all capacitors, disconnect the DMM test leads
and re-connect the circuit branch.
Note: The current jack has a protective fuse installed to protect the
meter from damage and the user from harm if a current larger
than specified is applied at the input. If the quick acting fuse
blows, replace with a like fuse.
