Before making any measurement, ensure the test leads are correctly connected and the function switch is set to the desired range.

7.1. AC / DC Voltage Idiwon

1. Set the function switch to the desired ACV (~) or DCV (---) range (e.g., 200V, 600V).
2. So okun idanwo pupa naa mọ jaketi VΩmA ati okun idanwo dudu naa mọ jaketi COM.
3. Touch the test probes to the circuit points where voltage ni ki won won.
4. Ka voltage iye lori LCD.

7.2. AC / DC Iwọn Iwọn lọwọlọwọ

Iṣọra: Never attempt to measure current on a circuit with voltage present across the current terminals. This can blow the fuse or damage the meter.

1. Pa agbara si Circuit.
2. Set the function switch to the desired ACA (~) or DCA (---) range (e.g., 200mA, 10A).
3. Connect the red test lead to the appropriate current jack (VΩmA for mA, 10A for 10A) and the black test lead to the COM jack.
4. Open the circuit where current is to be measured and connect the meter in series.
5. Apply power to the circuit and read the current value on the LCD.
