2. Enfòmasyon sou Sekirite

WARNING: To avoid electric shock or personal injury, and to avoid damage to the meter or to the equipment under test, observe the following safety rules:

  • Toujou asire w ke mèt la nan fonksyon ak seri ki kòrèk la anvan ou pran mezi.
  • Pa aplike plis pase rated voltage, jan yo make sou kontè a, ant tèminal yo oswa ant nenpòt tèminal ak tè tè a.
  • Pran anpil prekosyon lè w ap travay ak voltagse pi wo a 60V DC oswa 30V AC RMS. Sa yo voltages poze yon danje chòk.
  • Disconnect the test leads from the circuit before changing functions or ranges.
  • Pa sèvi ak mèt la si li sanble domaje oswa si izolasyon sou fil tès yo konpwomèt.
  • Remove the test leads from the meter before opening the battery cover or fuse cover.
  • Ranplase pil la le pli vit ke endikatè pil fèb la parèt pou asire lekti egzak.
  • Pa sèvi ak mèt la nan anviwònman ki gen gaz, vapè, oswa pousyè ki ka eksploze.

5. Enstalasyon

5.1 Enstalasyon batri

The M890G multimeter requires a 9V battery (not always included). To install or replace the battery:

  1. Asire w ke miltimèt la etenn epi fil tès yo dekonekte.
  2. Jwenn kouvèti konpatiman pil la sou dèyè mèt la.
  3. Unscrew the retaining screw(s) and carefully remove the cover.
  4. Konekte yon nouvo pil 9V nan klip pil la, pandan w ap obsève polarite ki kòrèk la.
  5. Mete pil la nan konpatiman an epi remete kouvèti a, byen sere l ak vis(yo).

5.2 Konekte fil tès yo

Toujou konekte fil tès nwa a nan COM jack. Connect the red test lead to the appropriate input jack based on the measurement type:

  • Pou Voltage, Resistance, Capacitance, Frequency, Diode, and Continuity measurements, connect the red lead to the VΩHz Jack.
  • For current measurements up to 500mA, connect the red lead to the mA Jack.
  • Pou mezi kouran jiska 20A, konekte fil wouj la ak 20A MAX Jack.

6. Operasyon Enstriksyon

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 Power On/Off

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.

6.2 Mezire DC Voltage (V=)

  1. Konekte plon tès nwa a COM ak fil tès wouj la pou VΩHz.
  2. Mete switch rotary la sou volim DC ou vle a.tage (V=) range. If the voltage se enkoni, kòmanse ak entèval ki pi wo a epi diminye jan sa nesesè.
  3. Konekte fil tès yo an paralèl ak sikwi a oswa konpozan ki anba tès la.
  4. Li voltage valè sou ekspozisyon LCD a.

6.3 Mezire AC Voltage (V~)

  • 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.
  • Kapasite (F): Set the rotary switch to the capacitance range. Connect the leads across the capacitor (ensure it is discharged first).
  • Frekans (Hz): Set the rotary switch to the frequency range. Connect the leads to the signal source.

7. Antretyen

7.1 Netwayaj

Siye kontè a ak piblisiteamp twal ak yon savon dou. Pa sèvi ak pwodui abrazif oswa solvang. Kenbe tèminal antre yo pwòp kont pousyè tè ak imidite.

7.2 Ranplasman batri

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 Ranplasman Fuse

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.
