(E) Transistor h
Measurement
FE
1. The transistor must be out of circuit. Set the
rotary selector knob to the h
2. Turn the meter on by pressing the power switch.
3. Plug the emitter, base and collector leads of the
transistor into the correct holes in either the NPN
of the PNP transistor test socket, whichever is
appropriate for the transistor you are checking.
4. Read the h
(beta or DC current gain) on the
FE
display.

5. SAFETY SYMBOLS

This marking adjacent to another marking or a terminal operating device indicates that the
operator must refer to an explanation in the operating instructions to avoid damage to the
!
equipment and/or to avoid personal injury.
This WARNING sign denotes a hazard. It calls attention to a procedure, practice or the like,
WARNING
which if not correctly performed or adhered to, could result in personal injury.
This CAUTION sign denotes a hazard. It calls attention to a procedure, practice or the like, which
CAUTION
if not correctly adhered to, could result in damage to or destruction of part or all of the instrument.
This marking advises the user that the terminal(s) so marked must not be connected to a circuit
point at which the voltage, with respect to earth ground, exceeds (in this case) 500 volts.
500V max.
This symbol adjacent to one or more terminals identifies them as being associated with ranges
that may in normal use be subjected to particularly hazardous voltages. For maximum safety,
the instrument and its test leads should not be handled when these terminals are energized.
position.

THE
TEST
-32-
(F) Capacitance Measurement
1. Connect red test lead to the "V CAP" input jack
and the black one to "COM".
2. Turn the meter on by pressing the power switch.
3. Set the rotary selector knob to the "FARAD"
position.
4. Set the rotary selector knob to the desired
capacitance position.
5. Short the leads of the capacitor to be tested
together to insure that there is no charge on the
capacitor.
6. Connect the leads to the capacitor and read the
capacitance value on the digital display.
The fuse rarely needs replacement and blow almost
always as a result of operator error. To replace the
battery and fuse (200mA/250V), remove the two
screws in the bottom of the case. Simply remove
the old battery or fuse and replace with a new one.
Be sure to observe the polarity when replacing the
battery.
