Chapter 6 – Measuring with the Pyroelectric and PD10 Heads

Configuring Measurement Settings

Averaging the Measurements (Power Mode Only)

The StarLab application automatically refines your readings and applies a
moving average. For pyroelectric heads, the StarLab application averages the
number display, not the graph display.

Note: You can use the Moving Average feature only while working in Power

mode. In Energy Mode, average measurements are displayed in the
Statistics Area only.

When you activate the StarLab application’s average mode, it displays the
average of the readings spanning from the last time average mode was activated,
to the present. Once the time period of the average is reached, the average
becomes a running average, spanning the average period backwards in time. For
example, if the average period is 30 seconds, at 15 seconds, the average is over
15 seconds; at 30 seconds, the average is over 30 seconds; at 5 minutes, it is over
the period from 4 minutes and 30 seconds to 5 minutes (30 seconds back from
the present).

To select an average period:

1. Select the average in seconds from the Average drop down list in the

Graph Configuration Area.

To disable averaging:

1. Select None from the Average drop down list in the Graph Configuration

Area.

or off. For more information on using the External Trigger, refer to Chapter 7 –
