VeriVolt Z32 Compliance System

---

The VeriVolt Z32 compliance system, was born of necessity, and has developed into an industry leading testing apparatus with accuracy and efficiency set as the cornerstone of the project.

The VeriVolt Test System is made up of three parts:

1. VeriVolt GPR - Control panel which includes onboard high resolution metering, test sequencing, and data averaging. The GPR serves as a standalone polarity and ground path return tester for verifying receptacles in patient care areas once they have been replaced per Z32 requirements.
2. VeriVolt LB - This is a separate load bank unit which can be connected to the GPR control unit to perform voltage drop tests required for Z32 testing in new builds, renovations, or when circuits in patient care areas have been altered.
3. VeriVolt Lite Software  - A cross platform data tracking application designed to enhance speed and accuracy of testing records, while tracking test intervals for Z32 specification recommended routine maintenance checks.

The overall system was designed to accommodate healthcare electrical systems entirely, from routine receptacle swaps, to any scale of new installation or renovations.

Version 1.0 (Obsolete)

• Manual test unit
• Onboard fixed value resistor loads
• Add-on multimeter data viewing
• Software creation for data recording
• Manual data entry
• Formula scale data values to expected rated amperage values per Z32 standard.

Version 1.1 (Obsolete)

• Load bank power port live at all times to allow cooling fans to run independent of test mode selection.
• Load bank operation only possible if power supplied to load bank for enhanced repeatability of test conditions. (Resistor values vary slightly when heated)

Version 1.2 (Obsolete)

• Integrated regulated current control
• Current scaled to match CSA Z32 80% of rated circuit amperage (12a for 15a circuit, 16a for 20a circuit) Note: function was added, accounting for minor non-linear resistance curves caused by termination points within a typical electrical circuit.
• Sub-versions (1.2x) transitioned away from fixed resistive loads to active current regulation

Version 1.3 (Current Version)

• Added onboard metering display and high bitrate data sampling.
• Calibration SOP development
• Introduction of on-board averaging and test sequence automation
• Introduction of integrated wireless based data transfer to VeriVoltLite software platform for errorless data entry

Version Projection:

• Version 1.3 is intended to serve as the foundation for new VeriVolt version 2.0.
• Firmware and hardware advancements will continue to be tested and deployed on v1.xx platform, with the best advancements serving as a benchmark for future versions.
