MEASURING FREQUENCY OR DUTY CYCLE
1. Connect the black test lead to the COM jack and the red to the"INPUT"
jack.
2. Set the range switch to "Hz/Duty" range.
3. Press the "Hz/Duty" Button to select "Hz" or "duty cycle" (%) mode.
4. Connect test leads across the source or load under measurement.
Note: The input voltage should be between 200 mV and 10 V rms AC. If the
voltage is more than 10 V RMS, reading may be out of the accuracy range.
NCV TEST (NON-CONTACT VOLTAGE)
1. "NCV" means "Non-Contact Voltage detection" without the test
leads.
2. Set the range switch to "NCV" range.
3. The Digital multimeter LCD screen show "NCV" icon and "EF".
4. Use the topside of the Digital multimeter to detect the object.
5. If there is 30 V AC ~ 1 000 V AC voltage, the Digital multimeter will make
a continuous sound.
TRANSISTOR HFE TEST
1. Set the range switch to "hFE" range.
2. Connect the adapter to the "COM" jack and the "INPUT" jack.
3. 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 transistor test socket of the adapter.
4. LCD display will show the approximate hFE value.
Note: This measurement can be used to determine whether the transistor
is good, and be used to compare the hFE of one transistor with the hFE of
another transistor; the reading on the display is only for reference.
