Description
Configurations include one element, one phase, and
neutral current, as well as two elements with two
phases
Needs special CE code
Description
Control of the chopping bit
Digital compensation using the GAIN_ADJ input of
the CE, based on linear and quadratic temperature
coefficients
Optional compensation of RTC by counting cycles on
mains.
Correction does not occur when frequency
measurement is inhibited by low voltages.
Constant rate compensation only.
2 nd -order compensation of RTC to 1ppb, using
temperature.
Correction does not occur when the ADC mux is off-
line.
Provides difference from calibration temperature to
0.1 C when calibrated
Description
Standard option of kilowatt hours, “3.
annunciator 3 at the beginning is optional if no other
registers are supported.
Standard option of 1 kh/pulse on both DIO 6 and DIO
2. 8K version’s pulse output is controlled by the CE
without MPU intervention.
