Unit of Competency MEM21005A - Diagnose faults in quartz watches
Description This unit of competency covers testing and diagnosing faults in electronic quartz watches.
Employability Skills This unit contains employability skills.
Learning Outcomes and Application This unit applies to work in watch service centres, jewellery and watchmaking stores and kiosks offering watch service and repair. The unit covers the skills required to diagnose faults where the power cell performance has already been tested and its condition is assessed as good or the correct terminal voltage under load but the watch continues to indicate faults or is stopped. Appropriate diagnostic testing procedures are required to identify or determine the faults in a quartz watch and the extent of servicing required. For repair of mechanical faults refer to the appropriate mechanical watch service units.Band: AUnit weight: 2 points
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.
Prerequisites/co-requisites MEM21001A Replace watch batteries, capacitors and bands

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

A person who demonstrates competency in this unit must be able to diagnose faults in quartz watches to industry standards, manufacturer specifications and in accordance with safety regulations and procedures.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Assessors must be satisfied that the candidate can competently and consistently:

select and perform appropriate tests

use testing equipment

analyse test results

determine faults based on test results and visual inspection

report most appropriate service procedures.

Context of and specific resources for assessment

Assessment may occur on the job or in a simulated working environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and information on workplace practices and OHS practices.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.

Method of assessment

Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessment may be in conjunction with assessment of other units of competency where required.

Guidance information for assessment

Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Required skills include:

using testing equipment (e.g. multimeter and quartz timing machines)

analysing test results for current consumption and voltage

solving problems

replacing cells

accessing and interpreting manufacturer service or technical guides

communicating with relevant personnel

replacing watch bands, straps or bracelets

Required knowledge

Required knowledge includes:

types of quartz watch construction and components

function/operating principles of electronic quartz watches

types of cells, power sources, capacitors and electronic storage units

observation and inspection techniques

occupational health and safety (OHS) regulations and procedures

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Record and document repair process

Record and document repair process may include:

accessing manufacturers' technical guides

prepare customer written quotation detailing faults

recommend most appropriate service procedure

estimate of replacement part

time spent on procedure

Tools and equipment

Tools and equipment may include:

watch case opening and closing tools

hand tools (e.g. tweezers, screwdrivers and eyeglasses)

Tests

Tests may include:

acoustic, capacitive and inductive pick-ups/sensors

quartz crystal oscillating signals (32 KHz)

voltage, resistance and current consumption

output pulses (integrated circuits)

pulse generation of step motor

lower working limit

rate (e.g. capacitive and inhibition)

Types of quartz watch

Types of electronic quartz watches may include:

analog display

digital display

duo display

anadigi

calendar and/or moon phase

chronograph

perpetual calendar

alarm

kinetic

auto quartz

Workshop testing equipment

Workshop testing equipment may include:

dials and hands

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
