Frequency & Revolution (Rpm) Measurement - UNI-T UT60D Operating Manual

Model UT60D: OPERATING MANUAL
Measurement Operation (6)
Note
l
The test leads can add 0.1
resistance measurement. To obtain precision
readings in low-resistance measurement, that is the
range of 340.0 , short-circuit the input terminals
beforehand and record the reading obtained (called
this reading as X). (X) is the additional resistance
from the test lead.
Then use the equation:
measured resistance value (Y) - (X) = precision
readings of resistance.
l
For high-resistance measurement (>1M ), it is
normal taking several seconds to obtain a stable
reading.
l
If reading with shorted test leads is not 0.5 ,
check for loose test leads, incorrect function selection,
or enabled Data Hold function.
l
The LCD displays
tested resistor or the resistor value is higher than
the maximum range of the Meter.
l
When resistance measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
