Scaling Alarm Setpoints

This section is for users who do not have WinPM.Net and must set up

alarms from the meter display. It explains how to scale alarm

setpoints.

When the meter is equipped with a display, most metered quantities

are limited to five characters (plus a positive or negative sign). The

display will also show the engineering units applied to that quantity.

To determine the proper scaling of an alarm setpoint, view the

the number in the Dec column for that register. For example, the

the Dec column is 1, the scale factor is 10 (10

=10). Remember that

scale factor 1 in Table 6–3 on page 81 for Scale Group D is

measured in kV. Therefore, to define an alarm setpoint of 125 kV,

enter 12.5 because 12.5 multiplied by 10 is 125. Below is a table

listing the scale groups and their register numbers.

Alarm Conditions and Alarm Numbers

This section lists the meter’s predefined alarm conditions. For each

alarm condition, the following information is provided.

• Alarm No.—a position number indicating where an alarm falls in

the list.

• Alarm Description—a brief description of the alarm condition

• Abbreviated Display Name—an abbreviated name that

describes the alarm condition, but is limited to 15 characters that

fit in the window of the meter’s display.

• Test Register—the register number that contains the value

(where applicable) that is used as the basis for a comparison to

alarm pickup and dropout settings.

• Units—the unit that applies to the pickup and dropout settings.
