Measuring Resistance - UNI-T UT58D Operating Manual

Measurement Operation(4)
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, the measuring time for high current
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 terminal of the Meter
C. Measuring Resistance
Warning
To avoid damages to the Meter or to the devices under
test, disconnect circuit power and discharge all the
high-voltage capacitors before measuring resistance.
