To measure low resistance, set up the Meter as Figure 6 and do the following:
5.
Press LO button to select low resistance measurement..
Insert the red test lead into the LINE terminal and the black test lead into EARTH terminal.
6.
7.
Connect the red and black alligator clip to the circuit to be measured. When the resistance is less than 30: the buzzer sounds.
8.
This range can test LED diode. Connect the anode LED diode to the red test lead, the LED diode will light up if it is good. If the LED diode does not light
up, it means it is damaged.
The Use of Power Adaptor
The use of power adaptor, see figure 7
Figure 7. The Use of Power Adaptor
5.
Open the side safey shutter, then you will see there is a power adaptor input terminal.
6.
Make sure the Meter is power off and Insert the UT511 power adaptor to the input terminal.
7.
It is highly recommed to take out all the batteries when you are using the power adaptor.
8.
Make sure the Meter is power off when you disconnect the UT511 power adaptor from the Meter.
