Introduction
The CH2 Performance Verification Kit allows you to verify calibration and proper operation of
the Cirris CH2 tester. Each CH2 Performance Verification Kit has a calibration date of five
years from the time of purchase. At the end of five years, the kit should be replaced or
recalibrated. Each component of this performance verification kit is tested with instruments
traceable to the NIST.
At least once a year, use the performance verification kit to verify the calibration of the CH2.
Also, use the kit whenever you suspect a problem with the CH2.
Note: There are no adjustments made to the CH2 tester during the performance verification
process. If the CH2 fails any step in the performance verification procedure, the tester must be
sent back to Cirris for repair.
For helpful information on setting up a calibration system to meet national calibration standards
such as ANSI/NCSL Z540-1, and ISO 10012-1, see Setting up a Calibration System in the
appendix of this manual.
This calibration procedure requires easy-wire software version 8.6 or higher.

5. When the CH2 Verification Assistant
prompts you to attach the meter leads to
the CH2 Low Voltage Test Adapter,
insert the positive lead into the top jack
and the negative lead into the bottom
jack.
6. Set the meter to the range shown in the
prompt (“Vdc” for example).
Be ready to read the meter! Once you
click Okay, a voltage will appear on the
meter. The value will only be shown for
several seconds so be ready to read it.
7. Read the meter and enter the value (in
volts) into the box on the Verification

Appendix
Setting Up a Calibration System
The information below is meant as an introduction to setting up a formal calibration system in
your organization.
Calibration Standards
Calibration standards refer to written quality system requirements for organizations that
perform calibrations and use calibrated equipment. Establishing a quality system according
to calibration standards helps ensure 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 referred 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/.
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:
Establish a recall system
How do you ensure that you don’t forget to send an instrument in for calibration? A recall
system can be a card file or a computerized database which 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.
Test Accuracy Ratios
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 should be at
least four times as accurate as the calibrated instrument.
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 CH2 Certificate of Calibration, which you can photocopy for your calibration, is provided
following this section.

Appendix
Calibration Data Report
So how accurate is the calibrated test instrument in relation to its published
specifications? Some organizations require 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 the out-of- tolerance data be recorded
in relation to the instruments specifications. A calibration data report can fill this requirement.
A calibration data report, you can photocopy to use for your CH2 calibration, is provided
following this section.
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.

Appendix
Creating Test Reports
The results of the performance verification are stored two of the following ways.
1. The CH2VerificationTest allows you to save a .csv file that contains the results of each
test performed on the measurement system of the CH2. The .csv file can be examined,
printed, and loaded into any spreadsheet program; it’s intended to be a key part of your
test results.
2. The results for all test runs (both the CH2VerificationTest and each of the
C_CalModule tests) are stored in the easy-wire database and are accessible from the
Test Archive Report or from the In Process Report, features of the easy-wire software.
Those reports save the summary of the testing that was done. If required, you can have
the CH2 save more information about the tests. To save more information for each test,
do the following steps:
Before running the test:
1. From the easy-wire Main Menu, click on the test program you wish to use to turn on
the test data storage options.
2. Click Edit.
3. At the top of the Test Program Editor screen, click the Set Test Defaults tab.
4. Check the Store measured test value box.
5. Check the Store High Voltage IR Values box (if the box is enabled).
6. Click Done at the bottom of the screen.
7. Select Yes, save changes and return to the main menu.
After the test program completes, while still in the test:
1. Click Reports at the bottom of the test program screen.
2. Click In Process Report and a test report will open.
3. Use the report’s Print Menu to print or create a .pdf of the report.
