WARNING
Do not apply more than 1000 V DC across the terminals or they will
be damaged.
7. Transistor Gain Measurements
WARNING
To avoid electrical shock and/or damage to the instrument, do not
apply more than 250 VDC or 250 ACrms between the hFE terminal
and the COM terminal.
Using the included multi-function socket, DC transistor gain (hFE)
can be measured. Follow these steps to make hFE measurements:
1. Set the rotary switch to
hFE
range.
2. Connect the “COM” plug and “+” plug of the special
multi-function socket to the COM and hFE terminals,
respectively, on the meter.
3. Determine whether the transistor to be tested is NPN or
PNP type and locate the emitter, base, and collector leads.
4. Insert leads of the transistor into the proper holes of the
special multi-function socket: “c” for collector, “b” for base,
and “e” for emitter.
5. The meter will show the approximate hFE value for the
test condition of base current 10 µA DC and Vce 2.8 VDC.
8. Temperature Measurements
WARNING
To avoid electrical shock, do not use this instrument when voltages
at the measurement surface exceed 60 VDC or 24 VACrms.
