Hyperterminal Alarm Alert with Alarm Suppression:
In this example, the Alarm Suppress is set to 2.
<ae2>Suppress Alarms = 2
secs=1: ch1-2: 0, 0 , bk= 429
secs=2: ch1-2: 681, 430 , bk= 2558
secs=3: ch1-2: 1629, 886 , bk= 444
Sample: ch1-2: 1629, 886 Range1= 10000, Range2= 5000.
Note:
The first line
starting with "Alarms" (in
boldface) shows what the
current alarm threshold is,
which channel is set for
alarming and how many
alarm conditions in a row
have occurred.
Alarms: Threshold= 1000, Channel= 1, # in a row=1
secs=1: ch1-2: 828, 517 , bk= 1640
secs=2: ch1-2: 1861, 1230 , bk= 434
secs=3: ch1-2: 3149, 2177 , bk= 449
Sample: ch1-2: 3149, 2177 Range1= 10000, Range2= 5000.
Alarms: Threshold= 1000, Channel= 1, # in a row=2
secs=1: ch1-2: 450, 126 , bk= 434
secs=2: ch1-2: 1279, 530 , bk= 444
secs=3: ch1-2: 1875, 678 , bk= 439
Sample: ch1-2: 1875, 678 Range1= 10000, Range2= 5000.
Alarms: Threshold= 1000, Channel= 1, # in a row=3
Note:
The "alarm alert"
(in boldface) doesn’t
display until after the 3rd
consecutive alarm
condition; the external
alarm light goes on at this
point as well.

Service High
and Service
Low
Service High and Service Low are the voltage levels at which the
Service Light will go on. Those levels are compared to the "Backlight"
measurement (seen as the bk= 1455 field) in every sample period. If
the Backlight measurement is greater than Service High or less than
Service Low, then:
Note:
The "normal"
levels seen in these "bk"
fields are examples only
and are not necessarily
what will be seen with the
instrument.
• the service alert appears as seen in the following Hyperterminal
Service Alert example:
• J10 pins 1 and 2 (Chans 1 and 2) = 2mA
• the Service Light is turned on
The default Service High threshold is 3500.
