measured resistance value (Y) – (X) = precision
readings of resistance.
l For high resistance (>1MΩ), it is normal
taking several seconds to obtain a stable reading.
l When there is no input, for example in open circuit
condition, the Meter displays “1”.
l When resistance measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test.
Measurement Operation(8)
F. The Model UT50C: Frequency Measurement (see figure 8)
Warning
To avoid harm to you or damages to the Meter, do
not attempt to measure voltages higher than 60V in
DC or 30V rms in AC although readings may be
obtained. When the frequency signal to be tested is
higher than 30V rms, the Meter cannot guarantee
accuracy of the measurement.
( figure 8)
red black
The frequency measurement ranges are 2kHz and 20kHz.
To measure frequency, connect the Meter as follows:
1. Insert the red test lead into the VΩ terminal and
the black test lead into the COM terminal.
2. Set the rotary switch to an appropriate measurement
position in kHz range.
3. Connect the test leads across with the object being
measured.
The measured value shows on the display.
