b. Enter Units/Count . The Units/Count is the output ratio from the device that is being input into the
meter. For example , if you have a KYZ module that is outputting a pulse every 1.8 kWh, with the
input set to Accumulator, Increment on Contact Opening, you would set the Units/Count to be the value
of the KYZ; in this case either 1.8 or a ratio of that number.
NOTE : When EOI is chosen for the Assigned to, a pulse is generated on the selected EOI Event.
When this option is chosen, you do not need to set Units/Count .
c. Enter Compression . The Compression Factor is used to adjust how high an accumulator will go
before rolling over. Because of this, it is useful for delaying rollover . For example , if you select a
Compression Factor of 10, each time 10 Pulse/State changes occur, the accumulator count will
increment by 1. The available Compression Factors are: 1, 10, 100, 1000, 10000 , and 100000 . The
default Compression Factor is 1.
d. Enter a Label for the Accumulator .
· The current Input Labels are displayed on
the screen. To change the Input Labels,
click in the Labels field you want to change,
and enter a new label.
Configuring a 0-1 mA Output Card (IQ250/260-IO3):
The 0-1mA Output Option Card is an analog communication card , which transmits a standard, bi-directional 0-1
milliamp signal. For technical specifications and hardware installation, see Chapter 7 of this manual.
An example use of the optional 0-1mA Output Card is in enabling the meter to communicate with an RTU (Remote
Terminal Unit).
1. Click 0-1 mA Output .
· You can set up to four Output IDs for your
Output Card.
2. Double-click an Assigned Channel field to add
or edit an Output ID . You will see the window
shown on the next page.
