Overview of the Column Department's Indicators and Test
Functions
Status Indicators
The instrument is provided with two status indicators which indicate the
operational state (prerun, run, and error states) of the instrument. The status
indicators provide a quick visual check of the operation of the instrument.
Error Messages
In the event of an electronic, mechanical or hydraulic failure, the instrument
generates an error message in the user interface. The following pages describe
the meaning of the error messages. For each message, a short description of
the failure, a list of probable causes of the problem, and a list of suggested
actions to fix the problem are provided.
Thermostat Function Test
The thermostat function test evaluates the heating and cooling efficiency of
the two peltier elements.
Temperature Calibration and Verification
The temperature calibration and verification procedure enables the
instrument temperature to be measured against an external, calibrated
measuring device. Normally, temperature calibration is not required
throughout the lifetime of the instrument. However, in order to comply with
local regulatory requirements, calibration and verification may be required.
The following sections describe these functions in detail.
