4. Configuración
Instalación de baterías
- Asegúrese de que o multímetro estea apagado e que os cables de proba estean desconectados.
- Localice o compartimento das baterías na parte traseira do medidor.
- Desenrosque a tapa da batería e retíraa.
- Insert four 1.5V (R03) batteries, observing correct polarity.
- Coloque a tapa da batería e fíxaa co parafuso.
Conexión de puntas de proba
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. Instrucións de funcionamento
The UT161B offers various measurement functions accessible via the rotary switch and function buttons.
Pasos xerais de medición:
- Turn the rotary switch to the desired measurement function.
- Connect the test leads to the appropriate input jacks and to the circuit under test.
- Lea o valor da medición na pantalla LCD.
- Use function buttons (e.g., RANGE, HOLD, REL, MAX/MIN) for additional control or data capture.
Funcións específicas:
- VoltagMedición (CA/CC): Select V~ for AC voltage or V- for DC voltage. The meter can measure up to 1000V.
- Medición de corrente (CA/CC): 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).
- Medición da resistencia (Ω): Select the Ω function.
- Medición de capacitancia (F): Select the F function.
- Medición de frecuencia (Hz): Select the Hz function.
- Diode/Continuity Test: Select the diode/continuity function. A buzzer will sound for continuity.
- Vol. Sen contactotage (NCV): Use the NCV function to detect AC voltage without direct contact. The meter will provide audible and visual indications.
