4.2. Povezivanje ispitnih vodova

Uvijek spojite crni mjerni kabel na COM priključak. Spojite crveni mjerni kabel na odgovarajući ulazni priključak na osnovu vrste mjerenja:

• Za Voltage, Resistance, Frequency, Duty Cycle, Diode, and Continuity measurements, connect the red lead to the VHzΩ+))|-- Jack.
• Za mikroampere (µA), milliampere (mA), and Battery tests, connect the red lead to the µAmA/BATT Jack.
• For high current (up to 20A) measurements, connect the red lead to the 20A Jack.

5. Uputstvo za upotrebu

5.1. Osnovna mjerenja

To perform basic measurements:

1. Turn the rotary switch to the desired function (e.g., V~ for AC Voltage, V- za DC Voltage, Ω za otpor).
2. Connect the test leads to the appropriate input jacks and then to the circuit or component under test.
3. Očitajte izmjerenu vrijednost na LCD ekranu.

5.2. Mjerenje temperature

Za mjerenje temperature:

1. Turn the rotary switch to the Temperature (℃/℉) function.
2. Spojite temperaturnu sondu na COM (negative) and µAmA/BATT and Temperature '+' (positive) jacks.
3. Place the tip of the temperature probe on or in the object whose temperature is to be measured.
4. Read the temperature value on the LCD display. Use the SELECT button to toggle between Celsius and Fahrenheit if available.

5.3. Battery Testing (1.5V~12V)

To test battery voltage:

1. Okrenite okretni prekidač u položaj BATT function (usually combined with µA/mA).
2. Spojite crni ispitni vod na COM utičnicu i crveni ispitni kabel do µAmA/BATT Jack.
3. Spojite crveni mjerni kabel na pozitivni pol baterije, a crni mjerni kabel na negativni pol.
4. Pročitajte zapreminu baterijetage na LCD ekranu.
