4. Honoa he pākahiko 9V hou 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

Honoa tonutia te taura whakamātautau pango ki te COM hononga. Honoa te taura whakamātautau whero ki te hononga whakauru e tika ana i runga i te momo ine:

• Mo te Voltage, Resistance, Capacitance, Frequency, Diode, and Continuity measurements, connect the red lead to the VΩHz koki.
• For current measurements up to 500mA, connect the red lead to the mA koki.
• For current measurements up to 20A, connect the red lead to the 20A MAX koki.

6. Nga Tohutohu Whakahaere

Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.

6.1 Hiko / Whakaweto

Turn the rotary switch from the OFF position to any desired function to power on the meter. To power off, turn the rotary switch back to the OFF position. The meter features an auto power-off function to conserve battery life after a period of inactivity.

• Transistor hFE Test: Insert the transistor into the hFE socket on the meter, ensuring correct Emitter, Base, Collector (EBC) orientation for NPN or PNP types. Set the rotary switch to hFE.
• Unga (F): Set the rotary switch to the capacitance range. Connect the leads across the capacitor (ensure it is discharged first).
• Auau (Hz): Set the rotary switch to the frequency range. Connect the leads to the signal source.

7. Tiaki

7.1 Te horoi

Horoia te mita ki te pānuitangaamp cloth and mild detergent. Do not use abrasives or solvents. Keep the input terminals free from dirt and moisture.

7.2 Whakakapinga Pūhiko

When the low battery indicator appears on the display, replace the 9V battery as described in Section 5.1. Failure to do so may result in inaccurate readings.

7.3 Whakakapinga Puka

If the meter fails to measure current, the fuse may be blown. Refer to the specifications for the correct fuse type. To replace the fuse:

1. Ensure the meter is off and all test leads are disconnected.
2. Open the battery compartment cover (and potentially an additional fuse cover, depending on the model).
3. Carefully remove the old fuse and replace it with a new one of the identical type and rating.
4. Securely close all covers.
