Measuring AC Voltage
1. Make sure the AC voltage is measured
2. Limit rotate in the direction of ACV measurement with a measuring limit is higher than the measured voltage. For example, measuring the voltage at 200 VAC then the measuring limit is 250 VAC.
3. Connect the probe to each pole of the source voltage (alternating each)
4. See the appointment of a needle on the scale board.

Measuring DC Voltage
1. Make sure the DC voltage is measured
2. Turn the gauge limit toward measuring DCV with limits higher than the measured voltage. For example, measuring the voltage at 200 Vdc measuring the limit is 250 VDC.
3. Connect the probe to each pole of the voltage source is the red probe to the positive pole and the black probe to the negative pole.

Disconnect test the Presence of a Conductor / PCB Track
1. Turn the gauge on the Ohm meter limit X1 / X10
2. Connect the probe to each end of the line / conductor to be tested.
3. If the needle moves point to zero, meaning the cable / line OK, and vice versa.

8. TRANSFORMERS
Transformer windings are composed of primary and secondary wires are wrapped around the iron core. Transformer can work only with AC voltage.
There are 2 types of transformer adapter:
1. TRAFO STEP DOWN (to decrease voltage)
2 . TRAFO STEP UP (to increase the voltage)
Transformer which we learn later is kind of a stepdown.

Measuring Transformers With Multitester
• Turn the limit measure on X1K Ohmmeter.
• Suppose the primary legs A, B, C
• Eg secondary leg D, E, F.
• Turn the limit measure on X1K Ohmmeter.
• Suppose the primary legs A, B, C
• Eg secondary leg D, E, F.
6. INTEGRATED CIRCUIT (IC)
IC is a combination of several components that are put together. To determine whether or not the IC can not be measured by multitester but immediately tried to the circuit.
IC has a particular series. IC there that has a 3 pin, 8 pin, 16 pin, and so forth. Pin number 1 is usually marked by a small circle near the pin. Example IC: LM 7812, UC 3842, TDA 1175, TDA 9302, etc..
