2. Ohutusalane teave
Always adhere to safety precautions when using the multimeter to prevent electric shock or personal injury. Read all safety information carefully before operation.
- Ärge tehke apply more than the rated voltage, nagu arvestil märgitud, klemmide vahel või mis tahes klemmi ja maanduse vahel.
- Ärge tehke use the meter if it appears damaged or if the case is open.
- Olge voldiga töötades äärmiselt ettevaatliktagüle 30 V vahelduvpinge RMS, 42 V tipp või 60 V alalispinge. Need pingedtagsee kujutab endast šokiohtu.
- Always ensure the test leads are in good condition, without any damage to the insulation.
- Enne funktsioonide või mõõtepiirkondade muutmist ühendage testjuhtmed vooluringist lahti.
- Täpsete näitude tagamiseks vahetage patarei kohe, kui ilmub patarei tühjenemise indikaator.
- Use the correct input terminals, function, and range for all measurements.

4. Seadistamine
Aku paigaldamine
- Veenduge, et multimeeter on välja lülitatud ja testjuhtmed on lahti ühendatud.
- Leidke patareipesa mõõturi tagaküljel.
- Keerake aku kaas lahti ja eemaldage see.
- Insert four 1.5V (R03) batteries, observing correct polarity.
- Asetage patarei kate tagasi ja kinnitage see kruviga.
Testjuhtmete ühendamine
Enamiku mõõtmiste puhul ühendage punane testjuhe VΩmA sisendpessa ja must testjuhe COM-sisendpessa. Suure voolutugevuse mõõtmiseks (kuni 10 A) ühendage punane testjuhe 10 A sisendpessa.
5. Kasutusjuhised
The UT161B offers various measurement functions accessible via the rotary switch and function buttons.
Üldised mõõtmisetapid:
- Keerake pöördlüliti soovitud mõõtmisfunktsiooni peale.
- Ühendage testjuhtmed vastavate sisendpesadega ja testitava vooluringiga.
- Lugege mõõteväärtust LCD-ekraanilt.
- Use function buttons (e.g., RANGE, HOLD, REL, MAX/MIN) for additional control or data capture.
Spetsiifilised funktsioonid:
- VoltagMõõtmine (vahelduv-/alalisvool): Valige vahelduvvoolu helitugevuse jaoks V~tage või V- alalisvoolu mahu jaokstage. The meter can measure up to 1000V.
- Voolu mõõtmine (vahelduv-/alalisvoolu): Select A~ for AC current or A- for DC current. Ensure test leads are connected to the correct current input jacks (mA/µA or 10A).
- Takistuse mõõtmine (Ω): Select the Ω function.
- Mahtuvuse mõõtmine (F): Select the F function.
- Sageduse mõõtmine (Hz): Select the Hz function.
- Diode/Continuity Test: Select the diode/continuity function. A buzzer will sound for continuity.
- Non-Contact Voltage (alternatiivne väärtus): Kasutage vahelduvvoolu helitugevuse tuvastamiseks NCV-funktsioonitage without direct contact. The meter will provide audible and visual indications.

6. Hooldus
Puhastamine
Pühkige ümbris koos reklaamigaamp lapiga ja õrna pesuvahendiga. Ärge kasutage abrasiivseid aineid ega lahusteid. Hoidke klemmid mustusest ja niiskusest puhtad.
Patarei vahetus
When the low battery indicator appears on the display, replace the batteries as described in the Setup section. Always use the specified battery type (four 1.5V R03 batteries).
Kaitsme vahetus
If the current measurement function fails, the fuse may need replacement. Refer to the detailed fuse replacement instructions in the complete user manual for your specific model. Ensure to use a fuse with the correct rating to maintain safety and performance.
7. Veaotsing
