SOP 6 - CALIBRATION OF VERNIER
CALLIPER GAUGES

Issue No.

E-1

INTRODUCTION
This procedure describes the steps taken when calibrating vernier calliper gauges of any dimension using the DIN 862 standard.

1.1

General aspects
Vernier calliper gauges are used to measure distances of either inside or outside measures or depths. Gauge blocks are used to calibrate the vernier calliper gauge.

2

MEASURING EQUIPMENT
Gauge blocks
Coordinate measuring machine

- ZEISS UMC 850

Gauge ring 50 mm

3

- ZEISS, 103 blocks
- MITUTOYO

RECEIPT
The vernier calliper gauge is received from the customer and is visually checked for any obvious defects. Defects which are checked are corrosion; missing or worn parts of the scale (on classical scales);

    Measurement and data processing is a topic discussed in IB Chemistry SL; it is important within the scientific community as it discusses the reliability of the data presented. Uncertainty is used to determine a range of a value in a measurement or instrument. Uncertainty of an analogue instrument is plus or minus half of the smallest division present; while uncertainty of a digital scale is plus or minus the smallest division present. To identify the amount of uncertainty, significant figures (the digits in measurement up to and including the first uncertain digit) are used. Certain rules are used to discover the number of significant figures in a value:…

    This article, written by Gover and MacKenzie (2003), illustrates a self-controlled design using a longitudinal study of 509 juveniles confined to 48 correctional institutions in 20 states conducted in two waves from April 1997 – August 1998. In the study, it was to be assessed whether or not there was a relationship between a juvenile who had experienced maltreatment (physical abuse, sexual abuse, witnessed family violence or possible neglect by a caregiver) and their level of anxiety and depression. They were provided a volunteer self-report survey consisting of 266 questions that included measures of child maltreatment, prior commitments, demographic factors and perceptions of the correctional institutions, conducted in groups of 15 to 20 juveniles in a classroom setting and took an average of 90 minutes to complete. The first time the survey was administered, the juveniles had an average of 3.4 months institutionalized and the second time had an average of 7.2 months. The mean maltreatment scale score was 1.62 on a five-point scale indicating low levels of maltreatment; however, 75% of the sample reported physical abuse, 54% reported viewing family violence, 20% neglect and 11% sexual abuse at least once in their childhood. Their anxiety, although low, decreased from 1.44 to 1.40 during the second wave of the study as well as their depression from 3.18 to 2.98, concluding that since the numbers decreased over the course of their institutionalization, therapeutic programming within the juvenile justice correctional system has proven to be effective with this class. With appropriate screening and assessment tools used to identify the histories of these juveniles, proper classification and treatment can be achieved in addressing these mental health issues and hopefully preventing future criminal acts following…

    Sampling Distributions

    In statistics, a simple random sample from a population is a sample chosen randomly, so that each possible sample has the same probability of being chosen. One consequence is that each member of the population has the same probability of being chosen as any other. In small populations such sampling is typically done "without replacement", i.e., one deliberately avoids choosing any member of the population more than once. Although simple random sampling can be conducted with replacement instead, this is less common and would normally be described more fully as simple random sampling with replacement.…
