Test Mode
Test mode is intended for factory use only.
In addition to normal and setup modes, test mode
provides a number of diagnostic functions for the
420
Plus
, including:
• Display raw A/D count
• Reset configuration parameters to default
values
• A/D internal calibration
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.
Figure 1-6 shows the Test Menu structure; Figure 1-7
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 1-7 summarizes the test menu functions.
