Audible Continuity Test

1. Red lead to "VΩmA", Black lead to "COM".
2. Set RANGE switch to " " range.
3. Connect test leads to two points of circuit to be tested. If the resistance is lower then 30Ω±20Ω, the buzzer will sound.
Transistor hFE Measurment
1. Set RANGE switch to the hFE range.
2. Determine whether the transistor is PNP of NPN type and locate the Emitter, Base and Collector leads. Insert the leads into the proper holes of the hFE
Socket.
3. The meter will display the approximate hFE value at the condition of base current 10μA and VCE2.8V.
Battery Test
1. Connect the black test lead to the "COM" jack and the red test lead to the "VΩmA" jack (Note: The polarity of the red test lead is positive "+").
2. According to the different type of the battery (1.5V, 9V, 12V) to be tested, set the range switch to the desired BATT range.
3. Connect the test leads to the battery to be tested.
4. Read the reading on the display. The polarity of the red test lead connection will be indicated.

Battery and Fuse Replacement

Fuse rarely need replacement and blow almost always as a result of operator error.
If the battery indicator appears in display, it indicates that the battery should be replaced.
To replace battery & Fuse (500mA/250V) remove the 2 screws in the bottom of the case, simply remove the old, and replace with a new one. Be careful to
observe polarity.
