Press the SELECT button momentarily to select the subject functions. Last selection
will be saved as power up default for repeat measurement convenience.
BeepLit Continuity function is having improved convenience for checking wiring
TM
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.
Conductance is the inverse of Resistance, that is S=1/ or nS=1/G. It virtually
extends the Resistance measurements to the order of Giga-Ohms for leakage
measurements.
CAUTION
Using resistance, continuity or nS 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
