red test lead to the V/Ω/Hz jack. ( NOTE: The polarity of
red lead connection is positive“ + ”)
2. Set the rotary switch at position and connect the
red lead to the anode, the black lead to the cathode of
the diode under testing. The meter will show the approx.
Forward voltage drop of the diode.
3.8 TRANSISTOR TEST
1. Set the rotary switch at hFE position.
2. Identify whether the transistor is NPN or PNP type
and locate Emitter, Base and Collector lead. Insert
leads of the transistor to be tested into proper holes of
the testing socket on the front panel.
3. LCD display will show the approximate hFE value at
the test condition of base current 10µA and Vce 3.2V.
4. SPECIFICATIONS
Accuracy is specified for a period of one year after
calibration and at 18°C to 28°C (64°F to 82°F) with
relative humidity to 80%.
Accuracy specifications are given as:
± % of reading ± number of least significant digits.
