• For current measurements (up to 10A), connect the red test lead to the A kāpeka.

6. Nga Tohutohu Whakahaere

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

6.1. Measuring AC/DC Voltage (V~ / V-)

1. Whakatakotoria te pana hurihuri ki V~ mo AC voltage ranei V- mo DC voltage.
2. Honoa ngā taura whakamātautau kia whakarara puta noa i te ara iahiko, i te wāhanga rānei e inehia ana.
3. Pānuihia te voltage uara kei runga i te whakaaturanga.

6.2. Measuring AC/DC Current (A~ / A-)

WARNING: Never connect the multimeter in parallel across a voltage source when in current measurement mode. This can cause a short circuit and damage the meter or circuit.

1. Turn OFF power to the circuit.
2. Whakatakotoria te pana hurihuri ki A~ for AC current or A- for DC current.
3. Connect the multimeter in series with the circuit, breaking the circuit to insert the meter.
4. Hoatu te mana ki te ara iahiko.

When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Use only new AAA batteries of the same type.

7.3. Whakakapinga Fuse

If the current measurement function fails, the fuse may need replacement. The DT4252 uses a 10A fused input. Refer to the detailed service manual for fuse replacement procedures, or contact qualified service personnel.

8. Te Raru

If the multimeter does not operate correctly, check the following common issues:

• Kore Whakaatu: Tirohia te tāutanga me te taumata utu o te pākahiko. Whakakapia ngā pākahiko mēnā e tika ana.
• Pānui hē: Ensure the function switch is set correctly for the measurement type. Verify test lead connections. Check for damaged test leads.
• "OL" (Overload) Display: The measured value exceeds the selected range. Switch to a higher range or ensure the input is within the meter's specifications.
• Kāore te Ine o Nāianei e Mahi Ana: Check the 10A fuse. If blown, it needs replacement by qualified personnel.

For persistent issues, contact Hioki customer support.
