2-32 Basic Analyzer Operations

Backlight – This ﬁeld is only available in the UltraSpec 8117 analyzer. It is

used to turn the analyzer’s backlight on and off. When on, the backlight

turns off automatically after one minute of key inactivity and back on auto-

matically when any key is pressed.

Load Firmware

This feature is used to load ﬁrmware and applications from the PC into the

analyzer. See “Installing the Application” on page 1-10 for complete

instructions on this procedure.

Review Calibration

To ensure maximum measurement accuracy, each UltraSpec analyzer is

thoroughly calibrated by CSI before shipping, and the results of the cali-

bration are recorded on the calibration tag that is shipped with the analyzer.

The values entered into the analyzer’s calibration routine allow the ﬁrm-

ware to compensate for any minor errors in measurement that may be

caused by component tolerances within the analyzer.

Normally, these values do not have to be modiﬁed. However, the analyzer

calibration values should be checked against the calibration tag under the

following conditions:

• The analyzer produces invalid or unreasonable readings.

• The battery has been allowed to discharge to the point where ana-

lyzer memory has been lost. (This typically would require several

months of inactivity.)

• New ﬁrmware has been loaded into the analyzer (UltraSpec 8000

analyzer only).

• The analyzer displays the “Warning – Check Calibration Factors”

screen.

Normally, the calibration values can simply be entered into the analyzer

using the values recorded on the calibration tag. It is recommended, how-

ever, that the analyzer be returned to CSI once a year for re-calibration in

order to maintain the instrument’s accuracy.
