1.3 Resistance Measurement
A re-configurable divider automatically provides a suitable full-scale range in
resistance measurement mode. The following table summarizes the full-scale
ranges and the reference resistors in each configuration.

Note: * When auto scan mode is set, continuity check is implemented in this range
** When auto scan mode is set, the 30.00MΩ range is omitted
1.3.1 Continuity check
Continuity check shares the same configuration with 300.0Ω manual resistance
measurement mode and has buzzer output to indicate continuity. The buzzer
generates 2KHz beep whenever the reading is less than 30Ω.
1.4 Diode Measurement
Diode measurement mode shares the same configuration with 3.000V manual
voltage measurement mode and has buzzer output to indicate continuity. The
buzzer generates a 2KHz sound whenever the reading is less than 30mV. If the
test circuit is open or the voltage drop between the two ports of the device (diode)
under test is larger than 2V, the LCD panel will show “OL”.
