Overview of the Module's Indicators and Test Functions

Status Indicators
The module is provided with two status indicators which indicate the
operational state (prerun, run, and error states) of the module. The status
indicators provide a quick visual check of the operation of the module.
Error Messages
In the event of an electronic, mechanical or hydraulic failure, the module
generates an error message in the user interface. 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 (see chapter Error
Information).
Thermostat Diagnostic Test
The thermostat diagnostic 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.
