Sample Mode; Test Functions - Teledyne 100E Instruction Manual

Operating Instructions
The second most common operating mode is the SETUP mode. This mode is used for
configuring various features and functions of the analyzer, such as the iDAS system, the
analog output ranges, or the COM port settings. The SETUP mode is also used for
performing various diagnostic tests during troubleshooting.
Finally, the various CAL modes allow calibration of the analyzer. Because of its
importance, this mode is described separately in Chapter 7. The mode field (upper left
corner) of the front panel display indicates the current operating mode.

6.2. Sample Mode

This is the analyzer's standard operating mode. In this mode, the instrument is analyzing
SO and calculating concentrations.

6.2.1. Test Functions

A series of test functions is available at the front panel while the analyzer is in SAMPLE
mode. These parameters provide information about the present operating status of the
instrument and are useful during troubleshooting (Section 11.1.2 ). They can also be
recorded in one of the iDAS channels (Section 6.10) for data analysis. To view the test
functions, press one of the <TST TST> keys repeatedly in either direction.
A value of "XXXX" displayed for any of the TEST functions indicates an out-of-
range reading or the analyzer's inability to calculate it.
All pressure measurements are represented in terms of absolute pressure.
Absolute, atmospheric pressure is 29.92 in-Hg-A at sea level. It decreases about
1 in-Hg per 300 m gain in altitude. A variety of factors such as air conditioning
and passing storms can cause changes in the absolute atmospheric pressure.
