Electrical Specifications

ANSI C12.1-3001 is the referring standard for tests listed in tables 3.2, 3.3, and 

3.4. 

Per Measurement Canada, Specifications/Standards LMG-EG-07 & PS-E-09-E 

are used to verify compliance with Canadian criteria. 

Compliance specifications

HHTR-3 

and 

EMTR-3

discharge

ANSI C12.1-3001 Test No. 28- “Effect of 

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.

and 

EMTR-3

Design Frequency 

Accuracy

+/- 50 parts per million.
