5. Tatūnga

5.1 Tāuta Pūhiko

The MS8233A requires one 9V 6F22 battery. If the battery is not pre-installed or needs replacement:

1. Me whakaweto te mita maha, kātahi ka momotu i ngā taura whakamātautau katoa.
2. Kimihia te uhi o te wahanga pākahiko kei muri o te waeine.
3. Unscrew the retaining screw(s) and carefully remove the cover.
4. Honoa te pākahiko 9V ki te topenga pākahiko, me te tirotiro tonu i te polarity tika.
5. Whakatakotoria te pākahiko ki roto i te wāhanga ka whakahokia te taupoki, me te whakau ki te/ngā tīwiri.

5.2 Te hono i nga kaiarahi Whakamātautau

Insert the test leads into the appropriate input jacks:

• Insert the black test lead into the “COM” (common) jack.
• Mo te nuinga o nga inenga (voltage, resistance, diode, continuity, temperature), insert the red test lead into the “VΩmA” jack.
• For DC current measurements up to 10A, insert the red test lead into the “10A” jack.

6. Nga Tohutohu Whakahaere

To operate the multimeter, turn the rotary switch to the desired function. The display will show the measurement value.

6.1 DC Voltage Ine (V–)

1. Whakatakotoria te pana hurihuri ki te DC Voltage e hiahiatia anatage awhe (hei tauira, 200mV, 2V, 20V, 200V, 600V).
2. Honoa te taura whakamātautau whero ki te taha pai (+) o te ara iahiko, me te taura whakamātautau pango ki te taha kino (-).
3. Pānuihia te voltage uara kei runga i te whakaaturanga.

6.2 AC Voltage Ine (V∼)

1. Tautuhia te huri hurihuri ki te Vol AC e hiahiatia anatagte awhe hiko (hei tauira, 200V, 600V).
2. Honoa ngā taura whakamātautau puta noa i te hiko ACtage puna.
3. Pānuihia te voltage uara kei runga i te whakaaturanga.

6.3 DC Current Measurement (A–)

1. Set the rotary switch to the desired DC Current range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
2. Hiranga: For 10A measurements, move the red test lead to the “10A” jack. For other current ranges, use the “VΩmA” jack.
3. Open the circuit where current is to be measured and connect the meter in series.
4. Pānuihia te uara o nāianei i te whakaaturanga.

6.4 Te Ine Ātete (Ω)

1. Whakatakotoria te pana hurihuri ki te awhe ātete e hiahiatia ana (hei tauira, 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
2. Me mohio kua whakakorehia te hiko, te waahanga ranei i mua i te ine i te parenga.
3. Honoa nga arataki whakamatautau puta noa i te waahanga hei ine.

7. Tiaki

7.1 Whakakapinga Pūhiko

When the low battery indicator appears on the display, replace the 9V battery as described in Section 5.1.

7.2 Te horoi

Mukua te keehi me te panuiamp kakahu me te hopi horoi ngawari. Kaua e whakamahia he mea whakakoi, he mea whakarewa rānei. Me whakarite kia maroke rawa te mita i mua i te whakamahinga.

7.3 Whakakapinga Puka

The current input jacks are typically protected by fuses. If the meter fails to measure current, the fuse may need replacement. Refer to the specific fuse ratings printed on the meter or in the detailed specifications. Fuse replacement should only be performed by qualified personnel.

8. Te Raru

If the multimeter does not function correctly, consider the following:

• Kāore he whakaaturanga, he whakaaturanga ngoikore rānei: Check battery charge and ensure it is correctly installed. Replace if necessary.
• Ngā pānui hē: Verify the correct function and range are selected. Ensure test leads are properly connected and making good contact. Check battery level.
• Cannot measure current: Check the fuse for the current input. Ensure the red test lead is in the correct current jack (e.g., 10A).
• “OL” (Overload) displayed: The measured value exceeds the selected range. Switch to a higher range or verify the circuit is not open.

Mena kei te haere tonu nga raru, whakapā atu ki te tautoko a te kaihoko.
