Product Usage Instructions

1. To measure DC voltage, select the appropriate range
   (200mV/2V/20V/200V/600V) and connect the multimeter’s probes to the
   circuit.
2. To measure AC voltage, select the appropriate range
   (2V/20V/200V/600V) and connect the multimeter’s probes to the
   circuit.
3. To measure DC current, select the appropriate range
   (200uA/2mA/20mA/200mA/10A) and connect the multimeter’s probes in
   series with the circuit.
4. To measure AC current, select the appropriate range
   (2mA/20mA/200mA/10A) and connect the multimeter’s probes in series
   with the circuit.
5. To measure resistance, select the appropriate range
   (200/2K/20K/200K/2M/20M/200M) and connect the multimeter’s probes
   to the resistor.
6. To measure capacitance, select the appropriate range
   (2nF/20nF/200nF/2F/100F) and connect the multimeter’s probes to the
   capacitor.
7. To measure diode, select the diode measurement function and
   connect the multimeter’s probes to the diode.
8. To measure temperature (UT151F), select the temperature
   measurement function and connect the temperature sensor to the
   multimeter.
9. To measure battery voltage (UT151A), select the battery
   measurement function and connect the multimeter’s probes to the
   battery terminals.
10. To check continuity, select the continuity measurement function
    and connect the multimeter’s probes to the circuit.
11. Ensure that the multimeter’s auto power off feature is enabled
    to conserve battery life.
12. Replace the battery when the low battery indicator is
    displayed.
