initializing the self-test procedure. It is an 8-digit code, with each digit being either 1
or 0, depending on whether an option is present or not. The positions of the digits to
be entered correspond to the options below:
To enter the proper configuration code, enter a “1” in the position corresponding to the
option if that option is present. (Be certain to enter only the digit “1”, any other entry
will be interpreted as a “0” by the system.) Enter a “0” if the option is not present.
For example, the CONFIGURATION CODE for a receiver with 4 analog outputs,
RS232 communication, and external battery kit, and 1 sensor connected to S1+ and
S1- terminals on the sensor interface TB3 (Refer to figure 2-3 or 2-4) is shown below:

The last four entries in the CONFIGURATION CODE correspond to the sensor channels
in the instrument that have the ability to perform the optional SENSOR CHECK routine.
Entries in these positions are only required to run the sensor check (refer to section
3.2.2.10) and are not required for the SELF-TEST to function properly.
If the configuration code that has been entered indicates that the appropriate option
is present, the extended self-test routine will be performed in the following sequence:

3.2.2.9.3 Self-test Failure Messages
Most tests simply exercise the hardware and do not detect an error, and therefore, do
not generate an error message. The messages for the tests that do detect failure are
given below. The test will stop at a failure and wait to the ENTER key to be pressed in
order to proceed with the remaining tests.
The self-test may be run in two modes:
• Single
• Repeat
The SINGLE mode performs the SELF-TEST sequence only once, then returns the
unit to the RUN mode if no problems occurred.
