MMAW NC II study guide
MMAW NC II · Work through your exam, one topic at a time.
Mechatronics Servicing NC II is a Philippine TVET qualification under TESDA that certifies a worker to install, configure, maintain, and troubleshoot automated production equipment that combines mechanical, electrical, electronic, pneumatic, and control elements. It suits maintenance technicians, machine builders, assembly-line electricians, and instrumentation staff who already work with or want to move into automated manufacturing, packaging, water treatment, or process plants. The MMAW NC II study guide has 9 sections and about 2,767 words.
01Workplace safety, 5S, and environmental regulations
Workplace safety, 5S, and environmental regulations questions test whether you can identify and control hazards before and during mechatronic maintenance, and whether you can keep the work area and waste streams compliant. Expect scenarios involving lockout/tagout, compressed air, chemicals, housekeeping, and waste segregation rather than definitions alone.
336 words, about 2 min02Interpretation of technical drawings, diagrams, and work instructions
This domain tests whether you can extract the right dimensions, views, symbols, and revision status from a drawing and turn them into a correct assembly or maintenance action. Questions often mix orthographic views, schematic symbols, title blocks, and work-instruction steps.
324 words, about 2 min03Hand tools, measuring instruments, and precision measurement
This domain tests correct tool selection, safe use, and measurement technique. The exam expects you to read vernier, micrometer, and dial instruments, check calibration, and distinguish precision measurement from rough work.
312 words, about 2 min04Electrical and electronic fundamentals, components, and circuit analysis
This domain tests basic circuit laws, component behaviour, and safe measurement in DC and AC control circuits. Expect relay coils, indicator lamps, diodes, capacitors, series/parallel networks, and multimeter use.
308 words, about 2 min05Pneumatics and hydraulics: components, symbols, and circuit behavior
This domain tests reading fluid-power symbols and predicting actuator force, speed, and control behaviour. Expect compressors, FRL units, directional valves, flow controls, cylinders, accumulators, and pressure relief.
299 words, about 1 min06Sensors, actuators, and industrial control devices
This domain tests how sensing devices connect to controllers and how actuators respond. Expect discrete and analog sensors, PNP/NPN outputs, sinking/sourcing inputs, relays, solenoids, and signal scaling.
303 words, about 2 min07Programmable logic controllers: programming, wiring, and troubleshooting
This domain tests ladder logic, I/O wiring, scan behaviour, and safe online diagnosis. Expect seal-in circuits, timers, counters, addressing, and input/output device checks.
313 words, about 2 min08Mechanical assembly, alignment, and preventive maintenance
This domain tests correct assembly practice, alignment measurement, fastening, lubrication, and planned maintenance. Expect bearing fits, coupling alignment, belt tension, torque sequence, and PM records.
280 words, about 1 min09Fault diagnosis, testing, and commissioning of mechatronic systems
This domain tests systematic fault-finding, safe testing, and proving a system after repair or installation. Expect input-to-output tracing, half-split testing, insulation and continuity checks, sensor simulation, and functional commissioning.
