Incubator Self Test
The Incubator Self Test of the ELx808 reader is designed to check for hardware
failures (such as open or shorted thermistors, A/D noise) and to verify that each of
the four zones in the incubation system are within ± 2° of the setpoint.
•
Temperature Setpoint
:
The desired temperature programmed by the
user, either through the reader’s keypad or Gen5.
•
Current Average:
Average temperature of the four zones of the incubator
at the time the system test is run. This number is displayed on the ELx808
front panel and sent to Gen5 if the reader is being computer controlled.
•
A/D Test:
Checks for allowable noise levels.

Zone #
: Reports the average temperature of the zone at the time the test is
run. Each zone is evaluated independently.
Min:
The minimum temperature recorded during the time that the system test
is run.
Max:
Maximum temperature recorded during the time that the system test is
run.
There is no range checking between Min and Max temperatures.
Range:
This test checks that each zone is within ± 2° of the setpoint.
Thermistor:
This test indicates whether the thermistors are functioning or
have failed.
Checksum Test
The Checksum Test compares the basecode software to internally recorded checksum
values to ensure that the programming has not been corrupted. The test runs
automatically when the instrument is turned on, and it can be run manually using the
keypad (
UTIL > TESTS > CHKSUM
). If the test fails, the reader will “beep”
repeatedly and display an error code; see
Chapter 6
.
When run manually, the software displays the part numbers and versions of software
currently loaded on the reader. For example:
Software P/N
Software Version
7340201
Version 3.21
Code Checksum:
