NOTE: To avoid the damage of the instrument,when online
measure the diode, be sure that power is turned off and
capacitors are released completely. Diode knob can be used to
measure voltage drop of diode or even other semiconductor
devices. The forward voltage drop reading should be 0.5V
~0.8V to a semiconductor devices with normal structure, it’s
open circuit when reverse voltage drop displays “1”, The
corresponding pole of black test leads is “+” and the red one
is “-” .
6.SQUARE WAVE SIGNAL OUTPUT
Set the knob to square wave range, ,the instrument output
square wave between
“V
Ω
mA” and “COM”.
NOTE: Square wave experiment signal with its rich harmonics can be used as a simple source repair equipment.
The frequence is approx. 50Hz,the output amplitude is over 3V under 1M
Ω
load .The output terminal of red test
lead should not touch voltage over 10V .
