Continuity function that is convenient for checking wiring
connections and operation of switches. A continuous beep tone

CAUTION
Using resistance or continuity function in a live circuit will produce
false results and may damage the meter. In many cases the suspected
component must be disconnected from the circuit to obtain an accurate
reading.
Auto Leads Resistance Calibration
When entering the 50 range manually by RANGE button for high precision
low resistance measurement, this feature will prompt you to short the inputs
for calibration. The display shows “Shrt”. Simply short the leads for about 3
seconds until the display shows zero, then the resistance in the leads and in the
internal protection circuitry of the meter is compensated automatically. The
compensation value can be as much as 5. If you need a compensation value
that is higher than that, Relative mode is recommended.
