Internship (WEEK 5)

Day 21 - 23/7/2018

Time : 0800-1800

Venue : NSF Engineering Sdn Bhd (HQ), Pasir Gudang

Activities :

1. Pressure Recorder calibration (Eftech International) – 7 units

• I was assigned to calibrate pressure recorder
• Pressure recorder is an electromechanical device that records mechanical input using different colour pens onto a circular charts.
• The accuracy class will cover 10% to 100% of the range. The test method maybe either by comparing selected indication with the pressure to be applied at these points or by comparing selected pressure with resultant indications of the unit under test(UUT). The test shall be made with increasing and decreasing pressure.

Day 22 - 24/7/2018

Time : 0800-1800

Venue : MPS Management & Services, Pasir Gudang

Activities :

1. Continue pressure recorder calibration form yesterday – 3 units
2. Hydraulic valve service

• Dismantle, cleaning, change O-ring, and leak test.
• After servicing the hydraulic valve, there is no more leakage during leak test.

Day 23 - 25/7/2018

Time : 0800-1800

Venue : Calibration Laboratory, NSF Engineering Sdn Bhd (HQ), Pasir Gudang

Activities :

1. Calibration of clamp meter 2003A, 2009R (KYORITSU)

• A clamp meter is an electrical device with jaws which open to allow clamping around an electrical conductor.
• Procedures:

1. Set function/ range switch to AC current as desire.
2. Press the jaw trigger to open the transformer jaws and clamp onto conductor coils. The closed jaws must be placed at the center of the conductor coils for maximum accuracy. Make zero adjustment to zero the display if the instrument has that function.
3. Ensure the direction of current flow is correct by use correct terminal from calibrator. Insert the red test lead from red terminal of Current Coil to Hi current terminal of calibrator. The black test lead is connected between black terminal of Current Coil and Lo terminal of calibrator.
4. For clamp meter have output voltage capability, connect the output terminal to the input of digital multimeter. Select the measurement function at digital multimeter to voltage function.
5. Ensure correct ratio is use by refer to manufacturer's specification. For example, ratio will indicate as 1A/1mV or 1A/10mV.
6. The display value then represents the product of the number of loop, and the actual measures current.
7. Follow the test point as indicated in respective UUT data sheet and record the results.
8. Repeat step (1) to (7) for DC Voltage Function.

Day 24 - 26/7/2018

Time : 0800-1800

Venue : Refinery and Petrochemical Integrated Development (RAPID), Pengerang

Activities :

1. Safety Course Induction for gate pass
