2. Drošības informācija

WARNING: Electrical shock hazard. Improper use of this meter can cause damage, shock, injury, or death. Read and understand this manual before operating the meter.

• Always ensure the meter is in good working condition and the test leads are not damaged.
• Nelietojiet vairāk par nominālo tilpumutage, as marked on the meter, between terminals or between any terminal and ground.
• Ievērojiet īpašu piesardzību, strādājot ar voltages above 25V AC RMS or 35V DC. These voltagtas rada trieciena risku.
• Pirms funkciju vai diapazonu maiņas vienmēr atvienojiet testa vadus no ķēdes.
• Do not operate the meter with the battery cover removed or loosened.
• Adhere to local and national safety codes. Use personal protective equipment (PPE) such as approved safety glasses and electrically insulated gloves.

4. Iestatīšana

4.1 Akumulatora uzstādīšana

The Voltcraft VC-11 requires a 9V battery for operation (not included). To install or replace the battery:

1. Pārliecinieties, vai multimetrs ir izslēgts, un atvienojiet visus testa vadus.
2. Atrodiet bateriju nodalījuma vāciņu mērierīces aizmugurē.
3. Izmantojiet skrūvgriezi, lai atskrūvētu skrūvi, kas nostiprina akumulatora vāciņu.
4. Uzmanīgi noņemiet vāku.
5. Pievienojiet akumulatora spailei jaunu 9 V bateriju, ievērojot pareizo polaritāti.
6. Place the battery into the compartment and replace the cover, securing it with the screw.

4.2 Testa vadu pievienošana

Always connect the black test lead to the 'COM' (common) jack. Connect the red test lead to the appropriate input jack based on the desired measurement:

• Sējtage (V), Resistance (Ω), Diode, and Continuity measurements, connect the red lead to the 'VΩmA' jack.
• For Current (A) measurements, connect the red lead to the 'VΩmA' jack (for mA range).

5. Lietošanas instrukcijas

Before taking any measurement, ensure the test leads are correctly connected and the rotary switch is set to the desired function and range.

5.1. Līdzstrāvas mērīšana Voltage (V=)

1. Iestatiet rotācijas slēdzi uz vēlamo līdzstrāvas tilpumu.tage (V=) range (e.g., 200mV, 2V, 20V, 200V, 250V). If the voltagJa e nav zināms, sāciet ar augstāko diapazonu un samaziniet pēc nepieciešamības.
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. Connect the test probes in parallel across the component or circuit to be measured.
4. Izlasiet sējtage vērtība LCD displejā.

5.2. Maiņstrāvas mērīšana Voltage (V~)

1. Iestatiet rotācijas slēdzi uz vēlamo maiņstrāvas skaļumu.tage (V~) diapazons (piemēram, 200 V, 250 V).
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. Connect the test probes in parallel across the AC source or component.
4. Izlasiet sējtage vērtība LCD displejā.

5.3 Measuring DC Current (A=)

1. Set the rotary switch to the desired DC Current (A=) range (e.g., 2000µA, 20mA, 200mA).
2. Connect the black test lead to the 'COM' jack and the red test lead to the 'VΩmA' jack.
3. BRĪDINĀJUMS: To measure current, the meter must be connected in series with the circuit. Break the circuit and insert the meter.
4. Connect the test probes in series with the circuit.
