PowerPlus 1557

Multi function installation tester with built-in certificates

Saves hours testing on-site
Intuitive and easy-to-use
17th edition certificates completed during tests

Overview Specification

PowerPlus 1557

The PowerPlus 1557 is a mult -function installation tester with a comprehensive range of fixed-wiring tests and built-in 17th edition certificates. As the tester completes tests, the results are automatically entered into the relevant field on a certificate which is stored on the tester itself. Results are verified to check for blank fields and to ensure only the correct information can be entered into the correct field. When used with the PowerPlus PC software, certificates can be uploaded to and from a PC for record traceability, printing certificates onto pre-printed stationary, or for retests.
