Model UT803: OPERATING MANUAL
Note
l
If the value of current to be measured is unknown,
use the maximum measurement position, and reduce
the range step by step until a satisfactory reading is
obtained.
l
For safety sake, each measurement time of high
current (>5A) should be less than 10 seconds and
the interval time between 2 measurements should
be greater than 15 minutes.
l
When current measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test, and remove the testing
leads away from the input terminals of the Meter.
