5. Transistor hFE Measurement:
1. Set the FUNCTION switch to hFE position.
2. Insert the E.B.C. of the PNP or NPN transistor to the proper
jack in the socket on the front panel.
6. Diode and Audible Continuity Measurement:
1.
Connect RED test lead to the “VΩmA” jack and BLACK test
lead to the “COM” jack.
2. Set the FUNCTION switch to the position and
connect the RED test lead to the ANODE of diode and BLACK
to CATHODE. The display will then show the approx. forward
voltage of this diode. If the test leads are connected the other
way round, the display will show an overrange status”1”.
3. Buzzer sounds if the resistance between the two probes less
then approximately 70 Ω,
7. 50 Hz Square Ware Output:
1.
Connect RED test lead to the “VΩmA” jack and BLACK test
lead to the “COM” jack.
2. Turn the FUNCTION switch to position and the RED
and BLACK test leads being the output jack.
ATTENTION
:
1. This function being the output message so don’t used
for measuring voltage.
2. The circuit being protected by short circuit device.
3. The voltage cannot exceed 40 Vp-p.
E. BATTERY REPLACEMENT:
•
Use the same specification battery (9 V 6F22) when necessary.
• When the voltage of the battery is low, the symbol or BATT
will appear on the display. Then the battery should be replaced.
