Channel Configuration

Channels can be configured either through the Data Logger Control Panel or the instrument interface:

■ Consult the Data Logger Control Panel Help system for information about configuration through the Control Panel.
■ Consult “L452 User Interface Screens” later in this Quick Start Guide for a table with all available configuration screens through the user interface. For detailed instructions about how to complete these screens, see the Model L452 User Manual.
When configuring through the instrument’s interface, each of the instrument’s two channels has its own set of configuration 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.
■ Define measurement units to use when displaying measurement data.
■ Define scaling to establish the relationship between input and measurement units.
■ Enable and define alarm triggers to determine if the instrument will report an alarm condition and the circumstances that will trigger an alarm condition. Channels must be configured before you start a recording session.

Recording Data

Recording sessions can be configured 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 configuring 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 configuring recording sessions.

Starting a Recording Session

You can start a configured 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 field on this screen specifies 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 field. 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 field 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 specified configuration settings. The recording session will end when the time interval defined by the Duration field 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 first 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 field to the next. If you press ► when the last number in the Start Date field is selected, the selection will move to the first number in the Start Time field. This will enable you to edit both the date and time in a single editing session. When you have finished entering the start date and time, press to save your changes.

4. You have two options for defining when the recording session will end. You can define when the recording session will end by either setting the Duration field in the
   Recording and Duration screen or through the Stop Date/Time screen. To set the Duration field, press ▲ twice to return to the Recording and Duration screen. Then, complete the Duration field. 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 reflect the Duration setting. For example, if the Duration field 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 fields as
   described in step 3 above.

6. When you have finished entering the stop date and time, press to save your changes. The Duration field in the Recording and Duration screen will be updated to
   reflect the duration defined 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 configuration 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 configure, start, schedule, stop, and cancel a recording session.
■ Channel 1 Configuration screens enable/disable Channel 1, determine what data is recorded by the channel, and how the data is displayed.
■ Channel 2 Configuration screens are identical to Channel 1 Configuration screens, except they apply to the instrument’s Channel 2.
■ Instrument Configuration screens configure general instrument settings.
■ Instrument Information screens display read-only settings on the instrument.

Each category has a “top level” screen that is the first screen that appears when you move to the category. The following table displays how the categories and screens are
organized.

Pressing the ► or ◄ button while in navigation mode will move from one category of screens to the next. These buttons work from any screen in a category. For example, pressing ► from any of the three Measurement Data screens displays the top-level Recording screen. The categories are cyclical, so pressing ► at an Instrument Information screen moves to the top-level screen in Measurement Data, while pressing ◄ in a Measurement Data screen displays the top-level Instrument Information screen.

The ▲ and ▼ buttons let you navigate the screens within each category. These are also cyclical; pressing ▲ in a category’s top-level screen displays the bottom level screen in
that category, while pressing ▼ at the bottom-level screen displays the category’s top-level screen.
