Set the Max Zs value [04-0101]

The Max Zs (earth fault loop impedance) value that CertSuite uses to autofill:

  • To autofill the Max Zs values, CertSuite originally used the 100% Max Zs values set out in Tables 41.3-41.6 of BS 7671:2018
  • Feedback has showed that some users prefer the 80% values listed in Appendix B of the IET On-Site Guide
  • CertSuite now gives users the choice of whether they use 80% or 100% values

To set the value at 80% or 100%:

  1. Go to the 'Admin' button on the top header bar and select 'Account Management' from the drop-down
  2. Select 'Company Profile' from the In-Job Menu on the left hand side
  3. Scroll down to the bottom of the page: until you come to 'Max Zs Scale'
  4. Click the toggle switch to select the 80% or 100% value
  5. This value will then show in your certificates and reports

The value can be changed at any time, provided you have 'Account Management' privileges: if you do not, contact your Account Administrator. If you have questions about account management, contact support: software@megger.com
