IHT Technical Reference
Running the Automatic Sequence
To run the test sequence press the
I
key. The green LED on the IHT
will begin to flash to indicate that the test sequence is running and the
status bar will indicate the current stage of the test.

• Press F1(PAGE) to step through the different views of the
instrumentation provided by the Test pages (See “The Test
Pages” on page 1 - 19 for more details).
• Press the
I
key a second time to trigger load correction. See
“Using Load Correction” on page 1 - 24 for more details on how
load correction works.
• Pressing F2 (MANUAL), F3 (EDIT TEST) or F4 (SETTINGS)
will pause the sequence at its current load value.
• Resume a paused test sequence by going back into Automatic
mode and pressing the
I
key. The sequence will restart with the
time remaining for the load step.
• The
+
and
-
keys can be used to adjust the percentage load
applied as the sequence is running. Press the
I
key to apply the
new load. This can be useful if you need to reduce the load
because the preset load is causing the generator to stall.
Note: If the “Cyclic
Auto Test” is selected in
the Control Options, then
the test will continue from
step 16 to step 1 in a
constant loop until
O
is
pressed to stop the test.
Press
O
at any time to stop the test sequence, reject the load and start
the fan delay.
If the Ramp Down on Reject function is enabled (see page 1 - 16) the
load will ramp down for 12 seconds before the fan delay starts. The
IHT’s LED will flash to indicate this. Press
O
a second time to reject
the load immediately if necessary.
