Model UT81B: OPERATING MANUAL
If the fuse burns out during measurement, the Meter
may be damaged or the operator himself may be
hurt.
To avoid possible damage to the Meter or to the
equipment under test, check the Meter’s fuses
before measuring current. Use proper terminals,
function, and range for the measurement. Never
place the testing leads in parallel with any circuit
or component when the leads are plugged into the
current terminals.
Turn off power to the circuit before test leads are
connected in series to the return circuit to be tested.
