Model UT805: OPERATING MANUAL
3. Connect the test leads across with the object being
measured as shown in figure 5. The primary display
shows the True RMS AC value, the effective reading
is only applicable to the range of 10%~100%. The
measured signal frequency value shows on the
secondary display. The sampling rate is around 1
time per second.
4. To measure AC signal with DC deviation, first press
ACV button, then press AC+DC button. Otherwise,
the primary display shows "--Err 1-", then back to
the present measurement range.
Note
l
When the input terminal is short circuit, it is allowed
to have maximum 500 digits of reading which does
not affect the accuracy.
l
When the Meter is at auto ranging mode, the True
RMS transducer needs a longer time to stablize and
it requires to process AC signal frequency
measurement. Therefore it takes a longer time to
obtain a stable reading when changing from one
reading to a relatively large reading.
l
When DC voltage 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.
