TIDM-HV-1PH-DCAC: Maximum voltage and current measurement range

Part Number: TIDM-HV-1PH-DCAC

Dear team:

One of my customers has the following questions during the use of the kit:

1) In the program, the maximum voltage and current measurement ranges are respectively defined by macros as:

#define VAC_MAX_SENSE 620.152f
#define VDCBUS_MAX_SENSE 620.152f
#define I_MAX_SENSE 15.6f

2) The calculated values in the excel table are:

Vbus_max_sense = 451.65Volts

Vac_max_sense=450.15Volts

Imax_sense = 16.968Amps

May I ask why the software calculation and the hardware test are inconsistent?

Best regards
