Electric Discharge (ESD)”
EMTR-3 Effect of Variation of
Frequency
ANSI C12.1-3001. Test #6
EMTR-3 Effect of Variation of
Voltage on the Metering
Device
ANSI C12.1-3001. Test #5.
HHTR-3
and
EMTR-3
Occupied Bandwidth 200 kHz. The ORION equipment transmits at
100 kilobits/second. The HHTR transmits at
9600 bits per second, but uses a wider frequency
deviation so that the occupied bandwidth is still
in the 200 kHz range.
HHTR-3
and
EMTR-3
RF Output Power FCC 15.249 compliant. IC RSS-210 A2.9; 2005
compliant.
