Calibration Schedule
Joulepoint recommends annual calibration for public charging sites and biannual checks for high-throughput depots.
Record calibration certificates in the asset record. The CSMS stores digital copies and surfaces renewal reminders 30 days in advance.
Test Equipment and Setup
Use a class 0.2s reference meter and maintain ambient temperature between 20 °C and 30 °C during testing.
Verify phase sequence, current transformers, and neutral conductors before beginning the load test sequence.
Validation and Reporting
Execute three-point load tests at 10%, 50%, and 100% of rated current. Record readings within the calibration worksheet template provided in the partner portal.
Submit reports through the compliance API endpoint /v1/meters/calibration. The CSMS updates status from DUE to VALID once the report passes automated checks.
