Diagnostics Mode
Diagnostic (DIAG) Mode
The Diagnostic (DIAG) mode menu lets you test
specific areas of the scale’s function.
These areas are:
Display (DISPLAY) – Shows the version and
revision of the software, followed by a display
segment test.
RAM (RA) – Performs a nondestructive test of
RAM in the processor. Displays “PASS” or
“FAIL.”
ROM (RO) – Performs a checksum of all loca-
tions in ROM in the processor. Displays “PASS”
or “FAIL.”
Input/Output (I-O) – Data is output by the scale
and through the use of a loopback connector the
data is immediately read back into the receive
channel and verified against what was sent.
“PASS” or “FAIL” is displayed. Requires a
jumper (short) between transmit and receive data
lines.
Division, test w/AZT (DIV-A) – Weight data is
normalized to 1,000,000 counts of displayed
resolution. AZT is enabled (Auto Zero Tracking).
Division, test w/o / AZT (DIV-N) – Weight data
is normalized to 1,000,000 counts of displayed
resolution. AZT is disabled.
Raw Counts (RA CNTS) – Non-normalized QDT
cell data (no zero tracking).
