How to Use Heles YX-360TRes Multitester to Test Resistance, DC Volt, AC Volt, DC Ampere, and Iceo Transistor

Electronic Kit School. - It is very important to know more about the instrument that used in electronic measurement project like to test the resistance of resistors, DC voltage, AC voltage, transistor condition, DC ampere, etc. And one instrument that very familiar for electronic hobbyist and student is Multitester.

Figure 1. Heles YX-360TRes Multitester

In the first my posting here,i will show you one of Multitester that will help me to measure or test many electronic project is Heles YX-360TRes Multitester like show in Figure 1 above. With this Multitester i can use it to measure Resistance, DC Volt, AC Volt, DC Ampere, and Iceo Transistor.

In here, i will try to show you information about this Multitester, like the appearance and part name and also how to use it to measure or test the resistance of resistor, DC voltage, AC voltage, DC ampere, Iceo transistor.

How to Test Resistance

To begin testing the resistance of resistor, please see the Figure 3. below that show the connection of Resistor and Multitester.

Figure 3. Resistor Testing Circuit

  1. Plug test leads in to COM and + sockets
  2. Place the range selector to a prescribed range position
  3. Short the test leads and turn 0 ohm ADJ to set the pointer to zero position
  4. Make sure that there is no voltage across the circuit to be tested
  5. Connect the test leads to the tested resistor and read the scale in accordance with the reference table
How to Test DC Voltage

To begin testing the DC Voltage, please see the Figure 4. below that show the connection of DC Source and Multitester.

Figure 4. DC Voltage Testing Circuit

  1. Plug the red test lead into the + socket and the black one into the COM
  2. Set the range selector to a selected DCV range position
  3. Connect the red test lead to the positive polarity of the circuit tested and the black one to the negative
  4. Read the DCV scale referring the reference table  
How to Test AC Voltage

To begin testing the AC Voltage, please see the Figure 4. below that show the connection of AC Source and Multitester.

Figure 5. AC Voltage Testing Circuit

  1. Plug the red test lead into the + socket and the black one into the COM
  2. Set the range selector to a selected ACV range position
  3. Connect the red test lead to the positive polarity of the circuit tested and the black one to the negative
  4. Read the ACV scale referring the reference table 
How to Test DC Ampere

To begin testing the DC current, please see the Figure 6. below that show the connection of the circuit that will test the current flow and Multitester.

Figure 6. DC Current Testing Circuit

  1. Plug the red test lead into the + socket and the black one into the COM
  2. Set the range selector to a selected DCA range position
  3. Connect the red test lead to the positive polarity of the circuit tested and the black one to the negative
  4. Read the DCA scale referring the reference table 
How to Test Iceo Transistor   

To begin testing the Iceo transistor, please follow step by step the connection of this transistor and Multitester as follow.
  1. Plug the test leads into + and COM sockets.
  2. Set the range selector to X10 for small size transistor, or to X1 for big size.
  3. Adjust 0 ohm ADJ to set the pointer to zero position of the ohm scale.
  4. Connect the transistor with the tester. For NPN transistor, the 'N' terminal of the tester is connected with the COLLECTOR (C) of the transistor and the 'P' terminal with the EMITTER (E). For PNP transistor, reverse the NPN transistor connection.
  5. Read icoe range, if the pointer is not within the LEAK zone or the pointer moves up near to the fullscale, the transistor tested is not good. Otherwise it is a good transistor.
