and the influence is much greater at low
temperature measuring range.
c) When the measurement has been completed,
disconnect the temperature probe.
Frequency Measurement
To measure frequency, connect the Meter as follows:
·
Set the rotary switch to desired 200kHz or 2kHz range
.
·
Connect the RED test lead into “V
Ω
” input terminal and
BLACK test lead into “COM” input terminal.
·
Connect the test leads across with the object being
measured.
·
Read the value from display, the unit is kHz.
·
Press HOLD button if need.
Warning
a) Don’t apply the voltage more than 250V RMS to the
meter at the frequency range.
b) When the measurement has been completed,
disconnect the connection between the testing leads
and the circuit under test and remove testing leads from
the input terminals.
Duty Cycle Measurement
To avoid harm to yourselves, never attempt to input
an effective voltage over 60V in DC or 30V in AC.
