2. Drošības informācija
Always adhere to safety precautions when using the multimeter to prevent electric shock or personal injury. Read all safety information carefully before operation.
- Nedrīkst apply more than the rated voltage, kā norādīts uz skaitītāja, starp spailēm vai starp jebkuru spaili un zemējumu.
- Nedrīkst use the meter if it appears damaged or if the case is open.
- Ievērojiet īpašu piesardzību, strādājot ar voltagvirs 30 V maiņstrāvas RMS, 42 V maksimālās jaudas vai 60 V līdzstrāvas. Šie spriegumitagtas rada trieciena risku.
- Always ensure the test leads are in good condition, without any damage to the insulation.
- Pirms funkciju vai diapazonu maiņas atvienojiet testa vadus no ķēdes.
- Lai nodrošinātu precīzus rādījumus, nekavējoties nomainiet bateriju, tiklīdz parādās zema baterijas uzlādes līmeņa indikators.
- Use the correct input terminals, function, and range for all measurements.

4. Iestatīšana
Akumulatora uzstādīšana
- Pārliecinieties, vai multimetrs ir izslēgts un testa vadi ir atvienoti.
- Atrodiet bateriju nodalījumu mērierīces aizmugurē.
- Noskrūvējiet akumulatora vāciņu un noņemiet to.
- Insert four 1.5V (R03) batteries, observing correct polarity.
- Uzlieciet atpakaļ akumulatora vāciņu un nostipriniet to ar skrūvi.
Testa vadu pievienošana
Connect the red test lead to the VΩmA input jack and the black test lead to the COM input jack for most measurements. For high current measurements (up to 10A), connect the red test lead to the 10A input jack.
5. Lietošanas instrukcijas
The UT161B offers various measurement functions accessible via the rotary switch and function buttons.
General Measurement Steps:
- Pagrieziet grozāmo slēdzi uz vēlamo mērīšanas funkciju.
- Connect the test leads to the appropriate input jacks and to the circuit under test.
- Nolasiet mērījuma vērtību LCD displejā.
- Use function buttons (e.g., RANGE, HOLD, REL, MAX/MIN) for additional control or data capture.
Specifiskās funkcijas:
- VoltagMērījums (maiņstrāvas/līdzstrāvas): Select V~ for AC voltage or V- for DC voltage. The meter can measure up to 1000V.
- Strāvas mērīšana (maiņstrāva/līdzstrāva): 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).
- Pretestības mērīšana (Ω): Select the Ω function.
- Kapacitātes mērīšana (F): Select the F function.
- Frekvences mērīšana (Hz): Select the Hz function.
- Diode/Continuity Test: Select the diode/continuity function. A buzzer will sound for continuity.
- Non-Contact Voltage (zemā nominālvērtība): Use the NCV function to detect AC voltage without direct contact. The meter will provide audible and visual indications.
