The multimeter is supplied with a pair of test leads (red and black).

• Whakauruhia te mata whakamātautau pango ki roto i te COM Hononga tāuru (noa).
• Mo te nuinga o nga inenga (voltage, resistance, low current), insert the mata whakamātautau whero ki roto i te VΩmA Jack tāuru.
• For high DC current measurements (up to 10A), insert the mata whakamātautau whero ki roto i te 10ADC Jack tāuru.

5. Nga Tohutohu Whakahaere

To operate the multimeter, select the desired function and range using the rotary switch.

5.1. Measuring DC Voltage (DCV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired DCV range (e.g., 200m, 2000m, 20, 200, 1000). Start with the highest range if the voltage kore e mohiotia.
3. Honoa nga arataki whakamatautau puta noa i te waahanga, iahiko ranei hei ine.
4. Pānuihia te voltage uara i runga i te whakaaturanga LCD.

5.2. Te Ine AC Voltage (ACV)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired ACV range (e.g., 200, 750). Start with the highest range if the voltage kore e mohiotia.
3. Honoa nga arataki whakamatautau puta noa i te waahanga, iahiko ranei hei ine.
4. Pānuihia te voltage uara i runga i te whakaaturanga LCD.

5.3. Measuring DC Current (DCA)

1. Mō ngā iahiko tae atu ki te 200mA: Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Mō ngā iahiko tae atu ki te 10A: Insert the red lead into the 10ADC jack and the black lead into the COM jack.
3. Set the rotary switch to the desired DCA range (e.g., 200μ, 2000μ, 20m, 200m, 10A). Start with the highest range if the current is unknown.
4. Whakawetohia te hiko ki te ara iahiko. Open the circuit where the current is to be measured.
5. Honoa te mita maha ki te ara iahiko mā te raupapa.
6. Tāpirihia te hiko ki te ara iahiko, ka pānui i te uara o nāianei kei runga i te mata LCD.

5.4. Measuring Resistance (Ω)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack.
2. Set the rotary switch to the desired Resistance (Ω) range (e.g., 200, 2000, 20k, 200k, 2000k).
3. Me whakarite kua whakakorea te hiko o te ara iahiko e whakamatautauria ana.
4. Honoa nga arataki whakamatautau puta noa i te waahanga hei ine.

3. Me whakarite kua whakakorea te hiko o te ara iahiko e whakamatautauria ana.
4. Connect the test leads across the component or wire.
5. If continuity exists (low resistance), the meter will emit an audible tone. The display will show the resistance value.

5.6. Diode/Transistor Verification Mode (hFE)

1. Insert the red lead into the VΩmA jack and the black lead into the COM jack for diode testing.
2. Set the rotary switch to the diode symbol.
3. Connect the red lead to the anode and the black lead to the cathode of the diode. The display will show the forward voltage drop. Reverse the leads; the display should show 'OL' (open loop) for a good diode.
4. For transistor hFE measurement, insert the transistor leads (Emitter, Base, Collector) into the appropriate sockets (E, B, C) in the hFE test socket, ensuring correct NPN or PNP type selection.
5. Read the hFE value on the LCD display.

6. Tiaki

6.1. Te horoi

Horoia te mita casing me te panuiamp he kakahu me te horoi ngawari. Kaua e whakamahi i te abrasive me te whakarewa. Me whakarite kua maroke katoa te mita i mua i te whakamahi.

6.2. Whakakapinga Pūhiko

Refer to Section 4.1 for battery installation instructions. Replace the 9V battery when the low battery indicator appears on the display to maintain measurement accuracy.

7. Te Raru

• Kore Whakaatu: Check battery installation and ensure the battery has sufficient charge.
• 'OL' or '1' on Display: This usually indicates an over-range condition or an open circuit. Select a higher range or check connections.
• Pānui hē: Ensure the correct function and range are selected. Check test lead connections and battery condition.
• No Continuity Tone: Verify the circuit is de-energized and the leads are making good contact.
