instructions about how to complete these screens, see the Model L452 User
Manual.
When conguring through the instrument’s interface, each of the instrument’s two
channels has its own set of conguration screens; the screens for one channel are
essentially identical to the screens for the other. These screens allow you to:
■Enable and disable the channel. When disabled, measurements are neither
recorded nor displayed for the channel.
■Select the type of input. This can be analog (voltage or current), pulse, or event.
Both channels must have the same input type.
■Dene measurement units to use when displaying measurement data.
■Dene scaling to establish the relationship between input and measurement units.
■Enable and dene alarm triggers to determine if the instrument will report an alarm
condition and the circumstances that will trigger an alarm condition.
Channels must be congured before you start a recording session.
Recording Data
Recording sessions can be congured and scheduled via the Data Logger Control
Panel, as explained in the Help. The instrument’s user interface also includes a set of
screens for controlling and conguring a recording session. These screens enable you
to:
■Specify the sample and storage periods to be used during the recording session.
■Start a recording session immediately.
■Schedule a recording for a future time.
■Set a length of time for the recording to run.
■Schedule start/stop dates and times for the recording.
■Stop an in-progress recording.
■Cancel a scheduled recording.
The Recording and Duration screen is the starting point for working with recordings.
This is the top-level screen for all recording-related activities. To see this screen,
display the “home” (Channel 1 & 2 Measurement Data) screen and press ►.
Consult the Model L452 User Manual for detailed information about conguring
recording sessions.

Starting a Recording Session
You can start a congured recording session immediately or schedule one for a later
date and time. To start a recording immediately:
1. At the “home” screen, press ► to display the Recording and Duration screen.
The Duration eld on this screen species the length of the recording session. By
default (assuming no session has been already scheduled), this is 15 minutes.
The Duration setting cannot be shorter than the Storage Period setting.
2. To change the duration setting, press to initiate selection mode and press ▼ to
select the Duration eld. Then, press to start edit mode and use the buttons to
enter a duration period.
For example, to change the duration from 15 minutes to 3 days, select the “1” in
“15 min” and press to begin edit mode. Use ▼ to change this to a zero. Then,
press ► to highlight the number “5.” Press ▼ twice to change this to “3.” Finally,
press ► to select the units and use the ▲ and ▼ buttons to cycle through the
available choices. These include s (seconds), min, hours, days, and weeks. Select
“days” and press to save your change. Alternatively, instead of the Duration
eld you can use the Stop Date and Stop Time screen to determine how long the
recording session will run.
3. To start the recording, press three times. The recording session will start
immediately using your specied conguration settings. The recording session will
end when the time interval dened by the Duration eld ends.
When a recording is active, the Recording icon will appear as a solid circle in the
icon bar at the top of the scree. If you attempt to turn OFF the instrument by pressing
while a recording is in progress, the message RECORDING ACTIVE will appear on
the screen. The button is disabled while a recording is in progress.
Scheduling a Recording Session
Instead of starting a recording immediately, you can schedule a recording for a future
date and time. You can only schedule one recording at a time. To schedule a new
recording, the active recording must run to completion, or you must cancel the earlier
recording.
1. At the “home” screen, press ► to display the Recording and Duration screen.
2. Press ▼ twice to display the Start Date/Time screen.
3. Press twice. The rst number under Start Date will be highlighted. Use the ▲
and ▼ buttons to increase or decrease the number and the ► and ◄ buttons to
move from one eld to the next. If you press ► when the last number in the Start
Date eld is selected, the selection will move to the rst number in the Start Time
eld. This will enable you to edit both the date and time in a single editing session.
When you have nished entering the start date and time, press to save your
changes.

4. You have two options for dening when the recording session will end. You can
dene when the recording session will end by either setting the Duration eld in
the Recording and Duration screen or through the Stop Date/Time screen.
To set the Duration eld, press ▲ twice to return to the Recording and Duration
screen. Then, complete the Duration eld.
To set the time and date for the end of the recording, press ▼ at the Start Date/
Time screen to display the Stop Date/Time screen.
5. By default, the settings on this screen reect the Duration setting. For example,
if the Duration eld is set to 24 hours, the stop date and time will be set to 24
hours after the start date and time. To change this, press twice. Then, use the
buttons to select and change settings, which is similar to setting the start date and
time elds as described in step 3 above.
6. When you have nished entering the stop date and time, press to save your
changes. The Duration eld in the Recording and Duration screen will be updated
to reect the duration dened by your start date/time and stop date/time.
7. If it is not already displayed, navigate to the Recording and Duration screen. Press
twice. Then, use the ▲ and ▼ buttons to toggle through the options. When
Schedule appears, press to select it.
When a recording is scheduled, the Recording icon will appear as an empty circle
in the icon bar at the top of the screen. You can turn OFF the Model L452 with a
scheduled recording pending. When the start date and time occurs, the instrument will
turn itself back ON for the duration of the recording and automatically turn OFF once
the recording is complete.
Stopping or Cancelling a Recording Session
As noted previously, you cannot start or schedule a recording session if a recording is
active or another scheduled recording is pending. In either case, you will need to stop
or cancel the recording before you can start or schedule another.
To stop an active recording or cancel a scheduled one, display the Recording and
Duration screen.
■If a recording is active, the only option available on this screen will be Stop.
■If a recording is scheduled, the only option available on this screen will be Cancel.
In either case, press the button three times to immediately stop or cancel the
recording, depending on the selection. The Recording icon will disappear, which
indicates that no recording is currently active or scheduled. In addition, the remaining
recording-related screens will become active and enable you to start or schedule a
new recording.

L452 User Interface Screens
The primary interface for working with the Model L452 consists of conguration and
display screens. These screens appear in the instrument’s front-panel LCD. You can
use the instrument’s buttons to navigate these screens, select options, and enter
information.
Screens are grouped into six categories:
■Measurement Data screens display data currently being measured on Channel 1
and/or Channel 2.
■Recording screens congure, start, schedule, stop, and cancel a recording
session.
■Channel 1 Conguration screens enable/disable Channel 1, determine what data
is recorded by the channel, and how the data is displayed.
■Channel 2 Conguration screens are identical to Channel 1 Conguration
screens, except they apply to the instrument’s Channel 2.
■Instrument Conguration screens congure general instrument settings.
■Instrument Information screens display read-only settings on the instrument.
Each category has a “top level” screen that is the rst screen that appears when you
move to the category. The following table displays how the categories and screens are
organized.
