Operating Basics

Programmer Interface Commands

The remote programming commands for all sampling modules are documented in
the

Programmer Guide

accessible from the instrument Help menu.

User Adjustments

All optical module setups, parameters, and adjustments are controlled by the
main instrument. To save, recall, or change any module settings, use the
main-instrument menus or front-panel controls. Consult the

Online Help

for

your main instrument.

Optimizing Measurement Accuracy

Performing the following procedures to increase (or maintain) the measurement
accuracy of the optical module:

Run Vertical Compensation

Clean the Optical Connectors

Run Dark-Level and User Wavelength Gain Compensations

Perform Vertical

Compensation

Performing a vertical compensation will maximize the accuracy of the automatic
measurements you take. This procedure uses internal routines to optimize the
vertical offset, gain, and linearity.

Overview

To perform optical compensations

Control elements and resources

Prerequisites

1.

Install the optical sampling module(s).

2.

Place dust covers on all optical module channels (or
otherwise turn off optical inputs to the module).

3.

Power on the instrument and allow a 20 minute
warm-up before doing this procedure.

4.

Set the acquisition to run continuously.

See the instrument user documentation and
online help for details on operating the instrument
controls.

Access the
compensation
routines

5.

Select

Utilities > Compensation

from the application

menu bar to open the Compensation dialog box.
The Compensation dialog box lists the main instrument
(mainframe) and installed sampling modules. The
temperature change from the last compensation is
also listed.

6.

Wait until the Status for all items changes from

Warm

Up

to

Pass
