BeepLit TM Continuity function is having improved convenience for checking wiring
connections and operation of switches. A continuous beep tone together with flashing
display backlight indicate a complete wire. Such audible and visible indications improve
continuity readabilities in noisy working environments.
In Diode function, the normal forward voltage drop (forward biased) for a good silicon diode
is between 0.400V to 0.900V. A reading higher than that indicates a leaky diode (defective).
A zero reading indicates a shorted diode (defective). An OL indicates an open diode
(defective). Reverse the test leads connections (reverse biased) across the diode. The digital
display shows OL if the diode is good. Any other readings indicate the diode is resistive or
shorted (defective).
CAUTION
Using resistance and continuity function in a live circuit will produce false results and may
damage the instrument. In many cases the suspected component must be disconnected
from the circuit to obtain an accurate reading.
CAUTION
Discharge capacitors before making any measurement. Large value capacitors should be
discharged through an appropriate resistance load.

Press the SELECT button momentarily to select the subject functions in sequence. Last
selection will be saved as power up default for repeat measurement convenience.
Note: Be sure to insert the banana plug type-K temperature bead probe Bkp60 with correct
polarities. You can also use a plug adapter Bkb32 (Optional purchase) with banana
pins to type-K socket to adapt other standard type-K mini plug temperature probes.
