4.1 Kuiswa kwebhatiri

The AN101 multimeter requires two 3V CR2032 batteries (not included) for operation.

1. Ita shuwa kuti multimeter yakadzimwa.
2. Tsvaga nzvimbo yebhatiri iri kumashure kweyuniti (tarisa Mufananidzo 3.4).
3. Using a small screwdriver, carefully remove the screw securing the battery cover.
4. Bvisa chivharo chebhatiri.
5. Insert two CR2032 batteries, observing the correct polarity (+/-) as indicated inside the compartment.
6. Tsiva chivharo chebhatiri uye chichengetedze nescuru.

4.2 Test Lead Connection

Batanidza bvunzo inotungamira kune akakodzera ekuisa jacks:

• Insert the nhema edza kutungamira mu COM (common) jack.
• Insert the tsvuku edza kutungamira mu VΩmA jack for voltage, resistance, diode, continuity, and current measurements up to 200mA.

5. Operating Instructions

The AN101 features automatic ranging for most measurements, simplifying operation. Always ensure the test leads are correctly connected and the function dial is set to the desired measurement type.

5.1 General Operation

1. Tendeudza switch inotenderera kune basa raunoda.
2. Batanidza tambo dzekuedza kudunhu kana chikamu chiri kuedzwa.
3. Read the measurement value on the LCD display.
4. Shandisa iyo SARUDZA button to toggle between AC/DC modes where applicable (e.g., Voltage, Current).
5. Shandisa iyo CHIYERO button to switch between auto-ranging and manual ranging.
6. Shandisa iyo BATA bhatani kuti uomese kuverenga kuripo pachiratidziro. Dzvanya zvakare kuti ubvise.

5.2 Kuyera DC Voltage (V–)

1. Gadzira switch ye rotary ku V–.
2. Connect the red test lead to the positive (+) side of the DC voltage source and the black test lead to the negative (-) side.
3. Verenga bhukutage value on the display. The meter will automatically select the appropriate range.

5.3 Kuyera AC Voltage (V∼)

1. Gadzira switch ye rotary ku V∼.
2. Batanidza bvunzo dzinotungamira mhiri kwe AC voltage source.
3. Verenga bhukutage value on the display. The meter will automatically select the appropriate range.

5.4 Measuring DC Current (µA–, mA–)

1. ZVINOKOSHA: Ensure the circuit is de-energized before connecting the meter in series.
2. Gadzira switch ye rotary ku µA– or mA– depending on the expected current.
3. Break the circuit and connect the multimeter in series with the load. The red lead connects to the higher potential side, and the black lead to the lower potential side.
4. Isa simba kudunhu.
5. Verenga kukosha kwazvino kuri pachiratidziro.

5.5 Measuring AC Current (µA∼, mA∼)

1. ZVINOKOSHA: Ensure the circuit is de-energized before connecting the meter in series.
2. Gadzira switch ye rotary ku µA∼ or mA∼ depending on the expected current.
3. Putsa dunhu uye batanidza multimeter yakatevedzana nemutoro.
4. Isa simba kudunhu.
5. Verenga kukosha kwazvino kuri pachiratidziro.

5.6 Kuyera Kupokana (Ω)

1. Iva nechokwadi chekuti dunhu kana chikamu chabviswa simba usati wayera kuramba.
2. Gadzira switch ye rotary ku Ω.
3. Batanidza bvunzo dzinotungamira mukati mechikamu kuti kuyerwa.
4. Verenga kukosha kwekudzivisa pachiratidziro.

5.7 Diode Test (→|•)

1. Ensure the diode is disconnected from any power source.
2. Gadzira switch ye rotary ku →|•.
3. Batanidza tambo tsvuku yekuyedza kune anode uye tambo nhema yekuyedza kune cathode ye diode. Chiratidziro chicharatidza vhoriyamu yekumberitage kudonha
4. Dzorera mawaya kumashure. Chiratidziro chinofanira kuratidza 'OL' (Open Loop) kuti chionekwe zvakanaka.

5.8 Continuity Test (→|•)

1. Ita shuwa kuti dunhu kana chikamu hachina simba.
2. Gadzira switch ye rotary ku →|•.
3. Batanidza bvunzo dzinotungamira padunhu kana chikamu.
4. If continuity exists (resistance below approximately 50Ω), the buzzer will sound. The display will show the resistance value.

6. Kuchengeta

6.1 Kuchenesa

Kuti uchenese multimeter, pukuta bhokisi racho nekushambadziraamp jira nesipo isina kusimba. Usashandise zvinogumbura kana zvinonyungudutsa. Iva nechokwadi chekuti mita yacho yakaoma zvachose usati washandisa.

6.2 Kutsiviwa kwebhatiri

When the battery indicator appears on the display, the batteries are low and should be replaced immediately to ensure accurate readings. Refer to Section 4.1 for battery installation instructions.
