2. Pamasangan batré

The HP-770J multimeter requires a 9V (6F22) battery for operation. To install the battery:

1. Tangtukeun lokasi kompartemen batré dina tonggong multimeter nu.
2. Use the provided small screwdriver to open the battery cover.
3. Pasangkeun batré 9V, pastikeun polaritasna (+ sareng -) bener.
4. Ganti panutup batré jeung amankeun ku screw nu.

Safety Note: Always ensure the multimeter is powered off and test leads are disconnected before opening the battery compartment.

3. Nyambungkeun Test Leads

Sambungan kabel tés anu leres penting pisan pikeun pangukuran anu akurat sareng aman.

1. Insert the black test lead into the "COM" (Common) jack.
2. Insert the red test lead into the appropriate input jack based on the measurement type:
   • Pikeun Voltage (V), Resistance (Ω), Temperature (Temp), Diode, and Continuity measurements, insert the red lead into the "VΩHz" jack.
   • For Current (A) measurements up to 20A, insert the red lead into the "20A" jack.
3. Ensure the test leads are tightly connected to the interface before performing any tests.

Operasi

The HP-770J features a rotary switch for selecting measurement functions and buttons for additional features like NCV and Data Hold.

1. Daya Hurung / Pareum

Pencét éta POWER button to turn the multimeter on or off. The device features an Auto Power Off function to conserve battery life.

2. Uji dioda

Pikeun nguji dioda:

1. Set the rotary switch to the Diode/Continuity position (Simbol dioda).
2. Sambungkeun kabel tés beureum ka anoda sareng kabel tés hideung ka katoda dioda.
3. Layar bakal némbongkeun voltase majutage drop. Reverse the leads to check for open circuit (OL) indicating a good diode.

3. Tés Résistansi

Pikeun ngukur résistansi:

1. Set the rotary switch to the desired Ohm (Ω) range.
2. Sambungkeun lead test kana komponén anu bakal diukur.
3. Baca nilai lalawanan dina tampilan LCD.

4. DC Test Ayeuna

Pikeun ngukur arus DC:

1. Set the rotary switch to the appropriate DC Amperage (A) range (e.g., 20A).
2. Catetan Kasalametan: Ensure the red test lead is in the "20A" jack for high current measurements.
3. Connect the multimeter in series with the circuit where current is to be measured.
4. Baca nilai ayeuna dina tampilan LCD.

5. Jilidtage Test (AC/DC)

Pikeun ngukur voltage:

1. Setel saklar puteran kana Voltase AC anu dipikahoyongtage (V~) atanapi Vol DCtage (V-) range.
2. Connect the test leads in parallel across the component or circuit to be measured.
3. Baca voltage nilai dina tampilan LCD.
4. Pencét éta TAHAN key to freeze the displayed value.

6. Non-Kontak Voltage (NCV) Function

Fungsi NCV ngamungkinkeun pikeun ngadeteksi voltase ACtage tanpa kontak langsung.

1. Pencét éta NCV kancing.
2. Move the top of the multimeter close to the wire or electrical outlet.
3. Lamun hirup voltage (≥90V AC rms) is detected, the NCV red and green LED lights will light up alternately, accompanied by an audible buzzer.
