Performing Diode/Continuity Test
Testing diodes
The diode test measures the forward voltage of a semiconductor junction of
approximately 0.5 mA. The beeper will emit a single beep tone when the input
voltage is below +0.7 V (approximately 1.4 k ) and emits a continuous beep
tone when the input voltage is below 50 mV (approximately 100 ).
Measurements are displayed as below:
Reading rate
Measurement display
Slow
1.2 V range
Medium

Fast
The measurement value will display OL (overload) when the voltage measured is
• > 1.2 V at slow reading rate
• > 2.5 V at medium and fast reading rate
