Product Functions

Analog quantity reference calibration: Provides a precise reference source for the three-phase voltage and current acquisition circuits of the SPM series meters, corrects the zero point and gain deviation of CT/PT sampling, and ensures the accuracy of voltage/current/power measurement (0.2S level calibration).

Factory calibration / on-site calibration: Special board for the entire SPM series (SPM6, SPM7, SPM8, SPM96, etc.) debugging, combined with EnerVista software for overall accuracy calibration and error correction.

Replacement for faults: When the sampling circuit of the SPM main board drifts or the measurement is inaccurate, ｒｅｐｌａｃｅ this calibration board to restore the meter's measurement accuracy.

III. Compatible Models

Full series of GE Multilin SPM multi-functional power meters: SPM60, SPM70, SPM80, SPM96, EPM9650 power quality meters.

Application Scenarios

Wind power box transformers, photovoltaic collection lines, factory power switch cabinets, substation control screens within GE SPM multi-functional meters as spare parts.
