5.2. AC/DC Current Measurement (mA~) / (mA=)
- Turn the rotary switch to the "mA~" (AC Current) or "mA=" (DC Current) position.
- Connect the red test lead to the "mA" input jack and the black test lead to the "COM" input jack.
- Tupato: To measure current, the multimeter must be connected in series with the circuit. Ensure the circuit is de-energized before connecting the multimeter.
- Wāwāhia te ara iahiko ka whakauru i te mita maha kia raupapa.
- Re-energize the circuit and read the current value on the display.
5.3. Ine ātete (Ω)
- Turn the rotary switch to the "Ω" (Resistance) position.
- Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
- Me whakarite kua whakakorea te hiko o te ara iahiko, te wāhanga rānei e inehia ana.
- Touch the test probes across the component.
- Panuihia te uara aukati kei runga i te whakaaturanga.

5.4. Logic Level Test
This function allows for quick testing of digital logic levels.
- Turn the rotary switch to the "LOGIC" position.
- Connect the black test lead to the "COM" input jack. The red test lead is integrated into the pen tip.
- Touch the pen tip to the point on the circuit where the logic level is to be tested.
- The display will indicate:
- Taumata teitei: Mena voltage he >3.5V
- Taumata Iti: Mena voltage is <3.5V
5.5. Diode Check (→|)
- Turn the rotary switch to the "→|" (Diode) position.
- Connect the red test lead to the "V" input jack and the black test lead to the "COM" input jack.
- Honoa te ine whero ki te anode me te ine pango ki te cathode o te diode.
- Panuitia te pukapuka whakamuatagmaturuturu iho i runga i te whakaaturanga. Hurihia ngā ine hei tirotiro i te tohu ara iahiko tuwhera (OL).
5.6. Whakamātautau Tonutanga (•)))
- Turn the rotary switch to the "•)))" (Continuity) position.
