• Mō ngā inenga au teitei (tae atu ki te 10A), whakauruhia te taura whakamātautau whero ki roto i te 10A koki.

7. Nga Tohutohu Whakahaere

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 Inenga

1. Set the function switch to the desired ACV (~) or DCV (---) range (e.g., 200V, 600V).
2. Connect the red test lead to the VΩmA jack and the black test lead to the COM jack.
3. Touch the test probes to the circuit points where voltage me ine.
4. Pānuihia te voltage uara i runga i te LCD.

7.2. AC/DC Inenga o naianei

Tupato: 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. Whakawetohia te hiko ki te ara iahiko.
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.

7.3. Te Ine Ātete

1. Me whakarite kua whakakorea te hiko o te ara iahiko, o te wāhanga rānei.
2. Set the function switch to the desired Resistance (Ω) range (e.g., 200Ω, 20kΩ).
