Page 23: Hold, Resume
Andy, an engineer with the Ajax Testing Company,
is running temperature and humidity tests on
navigational equipment. He runs the test profile,
Military Standard Test 810D, having already set
up the controller and programmed the profile.
In Step 4, the temperature in the chamber exceed-
ed the Alarm 1 setting. This triggered the alarm,
causing the indicator light on the front panel (next
to the bell-shaped icon) to light up and a message
to appear on the lower display: "TEMP DEV
High."
Because Alarm 1 was set up as a latching alarm
(Setup Page), Andy had to clear it manually. First
he corrected the alarm condition by widening the
gap between low and high deviation alarm set-
tings on the Operations Page. He then unlatched
the alarm by returning to the Main Page alarm
line and pressing the Right Key
.
again.
If your Series F4 is a single-channel controller,
you will see only the temperature on Channel 1.
This is not the true Military Standard Test 810D.

files Page) and look for MILSTD810D.
