Display Tab

Here you can change a number of characteristics

of the LCD display on the PT9250. By clicking in

the box you will see a menu of the display

choices that are available. You can also choose

to have the hand held display English/US units or

metric units (SI). Ventilation rate is displayed

either in cubic feet per minute (cfm) or liters per

second( l/s). Once you make a change press the

"send to sensor" button at the bottom of the

screen to transfer the new setting to the PT9250.

The new setting will be applied the next time the

sensor is powered on. The new settings will be

applied within a few seconds.

Logger Tab

This section discusses the data logging

adjustments and options available using the PC

interface. Further guidance on data logging and

its use is also provided in the next chapter. This

part of the program allows you to view logged

data, set the logger interval, and create a time

stamped text file that can easily be read by

programs like Excel®. The sensor can log up to

895 points for both temperature and CO

selections available on this tab are described

further below.

Application Guide

Sample Interval:

sensor can be adjusted from every 6 seconds to

every 4 hours using the selection menu. Once a

new setting is selected it must be sent to the

sensor and the sensor will have to be turned off

then back on for the new setting to take effect

Note: the battery charger should also be

disconnected from the PT9250.

Graphed Results:

turned on a new logger file is created and can be

identified at the top of the graphical display. By

clicking on the file you can view the set of data

for that file. The oldest files will have the lowest

number. Once the data logger has reached its

maximum capacity it will begin logging over the

oldest data. The graph function is very basic and

automatically adjusts the scale of the graph

based on the range of measurements observed.

For more options in graphing, the logged data

can be exported to a text file and graphed in a

program like Excel®.

that can easily be read by programs like Excel®.

When you export the file you will be asked to time

stamp the data (see below).

Time Stamping Exported Data:

PT9250 can record readings at a selected

interval it does not have a real time clock.

However it is possible to have the recorded data

date and time stamped when it is exported.

When you export the data you will be asked for

the date when the sensor was last turned off as

well as the time the sensor was turned off.

Based on this information all the data will be

assigned a date and time value. This has the

effect of adding two columns of information to the

data, one for the date and one for the time.
