4. Подешавање

4.1 Инсталација батерије

1. Уверите се да је мерач ИСКЉУЧЕН.
2. Пронађите поклопац одељка за батерије на задњој страни мерача.
3. Use a screwdriver to loosen the screw(s) and remove the cover.
4. Уметните нову батерију од 9 V, водећи рачуна о исправном поларитету (+ и -).
5. Вратите поклопац одељка за батерије и причврстите га завртњем (завртњима).

4.2 Повезивање мерних каблова

1. Фор волtage, resistance, and frequency measurements, insert the black test lead into the ЦОМ терминал.
2. Уметните црвени тест кабл у ВΩХз терминал.
3. For specific 2-channel measurements or other functions requiring a second input, refer to the operating instructions for connecting to the ЦХ2 терминал.
4. Ensure connections are secure before proceeding with measurements.

5. Упутство за употребу

5.1 Општи поступак мерења

1. Turn the rotary dial to the desired measurement function.
2. Повежите мерне каблове или clamp the jaws to the circuit under test as appropriate for the selected function.
3. Read the measurement value(s) on the dual LCD display.
4. If the reading is unstable or out of range, adjust the function or range if manual ranging is available.

5.2 Мерење наизменичне/једносмерне струје (Clamp)

This function measures current without breaking the circuit.

1. Окрените окретни точкић на A~ (Наизменична струја) или A- (Једносмерна струја) положај.
2. Отворите цлamp вилице притиском на окидач.
3. Enclose only one conductor of the circuit within the jaws. Ensure the jaws are fully closed.
4. Read the current value on the display. For DC current, observe the polarity.

5.3 АЦ/ДЦ Волtagе Мерење
