In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5D:
50 / 5D
= 10.
DFTHRH should be set to 10DD for this example.
5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically
caused by lower vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS
should be set higher to counter low frequency transients.
Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.

Test Mode
In addition to normal and setup modes, test mode provides a number of diagnostic functions for the
590 AG
Indicator
, including:
•
Display raw A/D count
•
Set A/D offset and gain calibration
•
Reset configuration parameters to default values
•
Print indicator configuration
To enter test mode, press and hold the setup switch until the front panel display shows the word
TEST
. After about
three seconds, the test mode display automatically shifts to the first test menu function, A/DTST.
A/D calibration functions, ADOFFS and ADGAIN, must be used only by qualified service personnel, and
only after replacing A/D converter components. Improper A/D calibration may render the indicator
unusable.
Figure 8-5 shows the Test Menu structure; Figure 8-6 shows the front panel key functions in test mode. Note that,
because the Test Menu functions are all on a single menu level, the
GROSS/NET
( ) key has no function. Press the
ZERO
( ) key to exit test mode.
Table 8-5 on page 47 summarizes the test menu functions.
