PRETEST NO. 1 (2ND GRADING)

It is an electronic measuring instrument that combines several measurement functions in one unit. Typically can measure voltage, current and resistance.

• LAN Cable Tester

• Multimeter

• Oscilloscope

• Signal generator

The two element/part of multimeter which used to connect the positive and negative line of the circuit.

• Meter Scale

• Range Selector Knob

• Range and Settings

• Test probes

It is part of a multimeter which used to point or read the measurement using the meter scale base of the range and settings you prepared during the test of a device or line of a voltage.

• Meter Scale

• Range Selector Knob

• Range and Settings

• Test probes

This part of the tester located center down of the body of the VOM is used to select the range and settings of the VOM the (AC and DC, Resistance, and the Amperage). Be sure to set this if ever you wanted to measure the voltage.

• Meter Scale

• Range Selector Knob

• Range and Settings

• Test probes

This part of the tester position in the whole corner of the range selector knows. Written here the voltages AC and DC, Resistance or ohms, and the amperage ranges.

• Meter Scale

• Range Selector Knob

• Range and Settings

• Test probes

This part of the tester which the basis of the measurement where the graduation, bar drawn in the body, commonly the resistance or ohms scale have a measurement from 0-2k ohms depend of the range and settings.

• Meter Scale

• The Pointer/Needle

• Range and Settings

• Test probes

This part of the tester is used to calibrate the tester whenever you wanted to measure the resistance. To assure that the tester calibrated to zero Ohms

• Meter Scale

• The Pointer/Needle

• Range and Settings

• Zero adjustment

This part of the tester which zero collector whenever you calibrate, the beginning as 0 voltages both the AC and DC measurement. Use your flat screw driver to set this knob to calibrate the 0 voltages of your tester.

• The Infinity Knob

• The Pointer/Needle

• Range and Settings

• Zero adjustment
