Introduction
The Touch1 LV Performance Verification Kit allows you to verify calibration and proper
operation of the Touch1 LV tester. Each Touch1 LV Performance Verification Kit has a
lifecycle of five years from the time of purchase. At the end of five years, the kit should
be replaced. All of the components for this performance verification kit are tested with
instruments traceable to the National Institute of Standards and Technology (NIST).
Calibration should be performed on your Touch1 LV tester at least once a year. You
should also check the calibration whenever you suspect the tester may not be operating
properly. If the Touch1 LV tester fails any step in the performance verification procedure,
it must be sent back for repair. No external adjustments can be made to fix the tester.
For information on setting up a calibration system to meet national calibration standards
such as ANSI/NCSL Z540-1, and ISO 10012-1, see the appendix of this manual.

Appendix
The following information can be used a guide for setting up a formal calibration system in
your organization.
Calibration Standards
Calibration standards refer to written quality system requirements for organizations that
perform calibations and use calibrated equipment. Establishing a quality system according
to calibration standards helps insure calibrations are done competently and lends credibility
to the calibration organization. In the United States, common calibration standards include
ANSI/NCSL Z540-1, ISO/IEC Guide 25, ISO 10012-1, and the former MIL-STD 45662A.
The ANSI/NCSL Z540 standard refered to above, as well as other helpful metrology
information, can be obtained from the National Conference of Standards Laboratories
International (NCSL) at 1-303-440-3339 or www.ncslinternational.org. You can obtain the
ISO standards from the International Standards Organization (ISO) at their web site
www.iso.net/.
The word “standards” is often used in another way in the metrology industry to refer to a
centralized, most accurate unit of measurement regulated by countries. The National
Institute of Standards and Technology (NIST) maintains the national standards for
measurements in the United States.
Good Calibration Practices
The calibration standards such as ANSI/NCSL Z540-1 and ISO 10012-1 require several
good practices for the calibration industry including the following areas:
Recall System
How do you ensure you do not forget to send an instrument in for calibration? Use a
recall system which can be a card file or a computerized database. This system
includes calibration dates, due dates, calibration sources, and other instrument
records. The recall system ensures calibrated instruments are recalibrated in a timely
manner.
Calibration Labels
How does someone know if an instrument has been calibrated without looking for the
paperwork in a filing cabinet drawer? When an instrument is calibrated, the calibration
standards require the instrument to be labeled as such. The calibration labels, which
are applied to instruments, have fields for the instrument serial number, calibration
date, calibration due date, and by whom. A good source of inexpensive calibration
labels is United Ad Label at 1-800-992-5755.
Accuracy Ratios
Can you use a ruler to calibrate your digital calipers? Of course not! Wherever
possible calibration standards require an accuracy ratio of at least four to one. In
other words, the insturment being used to measure the calibrated instrument must be
at least four times as accurate as the calibrated instrument.

Touch1 LV Checkout Manual - Page 15
Certificate of Calibration
How does everyone know you had an instrument calibrated? The calibration
certificate is the record of who, when, and by what equipment the instrument was
calibrated. A Touch1 LV Certificate of Calibration, which you can photocopy for your
calibration, is provided following this section.
Calibration Data Report
So just how accurate is the calibrated test instrument in relation to its published
specifications? Some organizations require that the measured values of a calibrated
instrument are written down when an instrument is calibrated. Calibration
laboratories typically charge extra to create a calibration data report. However when
a calibrated instrument is found to be out-of-tolerance, the calibration standards
require that the out-of-tolerance data be recorded in relation to the instruments
specifications. A calibration data report can fill this requirement. The Tester Checkout
Summary from the Touch1 tester can be used as a calibration data report. This report
can be printed or copied to paper by hand.
Traceability
Did qualified personnel perform the calibration procedure under controlled conditions,
using correctly calibrated instruments with the correct test accuracy ratios? To
maintain traceability, the answer to all these questions must be yes. Traceability
refers to each unbroken link of valid calibrations going back to national standards
such as those maintained by the NIST in the United States.
Several years ago NIST numbers (ie. reference numbers issued on NIST reports)
were commonly copied on successive calibration certificates as a means of showing
traceability. This practice has been discontinued. Therefore, if you are writing a
calibration procedure, do not require NIST numbers be copied on reports to show
traceability. NIST numbers are sometimes confused with other numbers that
calibration laboratories create for reference such as “asset numbers”, “NIST trace
numbers”, “ID numbers”, and report numbers. For more information regarding the
discontinued use of NIST numbers, Cirris can provide a copy of the position paper
from the National Conference of Standards Laboratories.
