Press HOLD button if need.
Warning
a) Do not apply any voltage to the input when the Meter is
working in contonuity test mode.
b) The open voltage of input terminal is approx. 3V.
c) 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.
hFE Measurement
Warning
To avoid damages to the Meter or to the devices
under test, do not input any voltage over 60V DC or 30V
AC.
To measure hFE, connect the Meter as follows:
·
Check that the transistor is PNP or NPN type.
.
·
Connect the transistor to be measured to the corresponding
jacks.
·
Read the hFE reference value from the display.
·
Press HOLD button if need.
