System Tests
This menu option allows you to check the Series 2000 control unit for
possible problems and to isolate where the problem might be. You may
be asked by AMETEK/Thermox personnel to access this menu option to
perform system diagnostics.
Performing these tests is not required under normal operations.
The following tests can be run using this menu option:
Calibrate A/D
Forces an A/D converter calibration. This is automatically done during
system start-up.
Test RAM
Checks the functionality of the control unit’s internal Random Access
Memory (RAM).
Test Keyboard
Tests that each key is functioning correctly.
Test EEPROM
Tests the electrically erasable programmable read-only memory.
Module Detect
Allows the control unit to check for the presence of option modules.
This test is used to ensure that the control unit is recognizing any op-
tion modules you have installed into the control unit. This is automati-
cally done during system start-up.
Test Digital In
Allows you to test the system digital input.
Erase RAM
Allows you to erase all RAM memory locations.
Erase EEPROM
Allows you to erase internal EEPROM memory locations if your
control unit is not operating properly. Be careful, though, because
selecting this option will erase all settings in your control unit, and the
default values will be reinstalled.
