27. Frequently Asked Questions
How can I know what values to use in each test setting?
If settings are not specied in the cable build instructions and you are hesitant about using the default settings in the soft-
ware, you can turn to the industry accepted wire assembly guide, A-620. More information about this guide can be found
by visiting cirris.com.
You can also calculate some settings using tools such as the Cirris calculators found at cirris.com.
Is high voltage testing dangerous?
Cirris testers are designed to comply with product safety regulations and are thus intrinsically safe. However, during a high
voltage test, there may be some risk. Children, women who are pregnant, and people with pacemakers should not perform
high voltage testing. For more ideas on high voltage safety, visit cirris.com.
How do I calibrate my tester?
The act of calibrating a tester should only be performed by Cirris or a third-party calibration lab. To verify calibration and
functionality, you can purchase a Performance Check Kit from Cirris.
Every Cirris tester that leaves our factory is calibrated in compliance with ANSI/NCSL Z540-1-1994 and ISO-10012 to stan-
dards traceable to the NIST in the United States. For more information, visit cirris.com.
The calibration of the tester should be veried annually.
Where do I nd current manuals?
The most current manuals can be found by contacting your Cirris representative or visiting cirris.com.
27.1 Service and Maintenance
■ General Maintenance
Do not open the tester chassis. Opening the chassis will void your warranty. The 4200 Series tester contains no internal user
serviceable parts. Cleaning or routine maintenance of internal parts should be done at Cirris.
Do not try to replace the lithium battery on the MCAN board. Should this battery, or any internal parts malfunction, contact
Cirris for a repair.
Any exterior cleaning should be done using a clean, damp rag. Avoid using cleaning agents or chemicals on any part of the
unit.
27.2 Connector Maintenance
The DB-25 Connectors on the front of your tester are made to be durable, but over time the connectors can be damaged
either from age or abuse/misuse. To protect your tester’s connectors:
● Never insert foreign objects into your connectors.
● Keep the connectors free of dust and debris.
● Be mindful of bent pins or other problems with mating connectors.
