2. PRODUCT FEATURES
The AEMC Data Logger Model L452 is a two-channel data logger. The instrument is Bluetooth-enabled and records DC voltage, DC
current, pulse count, and event input. Typical applications include process control and measurement, utility metering, and environmental
monitoring.
Figure 1. Data Logger Model L452
2.1 Model L452 Features
The Model L452 combines the functionality of three earlier Simple Logger II products: the Model L322 (4 to 20mA logger), Model L432
(user-selectable ±100mV, ±1V, and ±10V logger), and Model L404 (event logger). Voltage and current measurements can be sampled
from 200ms to 1 minute; sampled quantities can be averaged (mean value) from 200ms to 1 hour and recorded.
Primary features include:
■Multiple data input types. The Model L452 can log DC voltage, DC current, pulse count, or event data, using either one or
two inputs. Measurements can be performed directly on the instrument through a variety of sources, such as sensors. This
data can be stored in the instrument’s 32MB internal memory.
■ User interface. You can set up the instrument and view measurement data through the front panel LCD screen and input
buttons. The L452 features an on-board interface for navigating measurement data and selecting conguration options.
■ DataView support. The instrument connects to a computer using either Bluetooth or USB. Once connected, recorded data
can be downloaded, analyzed, and formatted into reports using DataView’s Data Logger Control Panel. This Control Panel
also enables you to change settings on the instrument, view real-time measurements, schedule recording sessions, and
perform other conguration tasks.
The Model L452 includes two modes of operation:
■Local mode provides setup and measurement data display through the instrument’s LCD screen. In Local mode, you can
select conguration settings, start and stop a data recording session on the instrument, and view measurement data.
■ Remote mode controls the L452 from “outside.” You can connect the instrument directly to a computer and then work with it
through the DataView Data Logger Control Panel (see § 6). Remote mode can be enabled automatically (when the instrument
is actively communicating with the computer) or manually by selecting an option in the Control Panel.
Working environments for the Model L452 include factory oors, utilities, and any area being monitored for environmental or process
trends. Users of the Model L452 include utility personnel, factory technicians, environmental monitors, and others. Typical applications
include process measurement, utility metering, monitoring a battery’s charge, and any application involving phenomena recorded over a
period of time.

2.2 Electrical Power
The instrument can operate on two sources of power:
■USB cable connected to an external power source, such as a computer
■Two internal 1.2V AA rechargeable NiMH batteries
You must insert the batteries into the instrument before use, even when operating on USB power. Consult §8.1.3, “Installing and Replac-
ing the Batteries,” for instructions about how to do this.
2.3 Using the Model L452 User Interface
Before using the Model L452 for the rst time, you should take a few minutes to familiarize yourself with the instrument’s user interface.
This consists primarily of a set of screens that appear on the L452’s LCD, and the buttons used to navigate these screens, select options,
and enter conguration information. These buttons and screens operate in combination to enable you to view displayed data, select the
congurable parameters, and modify these parameters. The functions performed by the buttons depend on what operational mode (navi-
gation, selection, or edit) the L452 is currently in:
■Navigation mode is the default state for the user interface. In navigation mode the Up ▲, Down ▼, Left ◄, and Right ►
buttons are used to navigate through the columns and rows of screens.
■Selection mode is initiated by pressing the Enter button while in navigation mode in any conguration screen. In selection
mode the buttons are used to select a conguration parameter, or an individual value within a multi-value parameter. The
selected user-editable option appears in blinking reversed text (light on dark background).
■Edit mode is started by pressing the button in selection mode. In edit mode buttons are used to change the value of the
currently selected congurable parameter. When in edit mode, editable elds appear in solid (non-blinking) reversed text.
2.3.1 Model L452 Screens
The screens that appear on the instrument’s 128 x 64 graphical LCD serve as the primary interface through which you interact with the
instrument locally. These screens, in conjunction with the buttons on the front panel, provide the features and functionality that enable the
Model L452 to operate as a standalone instrument.
Screens are organized into six categories:
■Measurement data screens display the measurement data (including minimum and maximum values) for the two input
channels.
■ Recording screens start, stop, schedule, and congure recording sessions.
■ Channel 1 conguration and Channel 2 conguration screens set a variety of parameters for each channel on the
instrument, including input type, measurement units, scaling, alarms, and related information. (Note that input type must be the
same for both channels.)
■ Instrument conguration screens set general parameters and perform tasks on the instrument, such as setting the display
language, erasing memory, resetting the conguration to default settings, setting date/time, and modifying Bluetooth settings.
■Instrument information screens are display-only and show current instrument information.

2.3.2 Front Panel Buttons
The Model L452 interface also includes a set of buttons:
Figure 3
These buttons, in conjunction with the LCD, provide the built-in ability to congure the instrument and view measurement data, without
requiring a computer connection.
Button Description
Left and Right: These buttons move from one category/column of screens to the next. Pressing ► while viewing
any measurement data screen displays the top-level recording screen. Pressing ◄ while any recording screen is
displayed returns you to the top-level measurement data screen. This functionality is “circular” – pressing ◄ while a
measurement data screen is displayed navigates to the top-level instrument information screen; pressing ► while an
instrument information screen is displayed goes to the top-level measurement data screen.
- In selection mode, ◄ and ►move within multi-part input elds such as Recording Duration.
- In edit mode, ◄ and ► are individually inactive in option selection elds, and active in text and numeric entry
elds.
- Pressing both buttons simultaneously terminates the editing session without saving any changes and returns
to navigation mode.
Up and Down: These buttons navigate through the individual screens in a category. Pressing ▼ while in the top-
level measurement data screen (Channels 1 & 2 Measurement Data) displays the Channel 1 Measurement and Min/
Max Data screen; pressing it again displays the Channel 2 Measurement and Min/Max Data screen, and so on. This
functionality is “circular” - pressing ▼ while a bottom-level screen is displayed returns you to the top-level screen in
that column.
- In selection mode ▲ and ▼ navigate to user-editable elds on the screen; as you do, the currently selected
eld blinks in reversed text.
- In edit mode ▲ and ▼ either (1) cycle through the available options for the eld, or (2) enter text characters in
text-editable elds such as Bluetooth Name.
Enter: This button, when pressed at a user-congurable screen, enables you to select and change displayed set-
tings. (Pressing at an information-only screen has no e󰀨ect.)
- Pressing once initiates selection mode. This causes the rst user-congurable eld in the screen to be
highlighted in blinking reversed (light on dark) text. You can then use ▲ and ▼ to navigate to other user-edit-
able elds on the screen; as you do, the currently selected eld blinks.
- Pressing a second time while positioned on a blinking eld initiates edit mode. This enables you to change
the settings for that eld. The selected eld stops blinking but remains highlighted in reversed text. You can
then use ▲ and ▼ to cycle through the available options for the eld, or enter text characters in text-editable
elds.
- When the desired option is displayed (or text entry is complete), pressing a third time ends the editing ses-
sion, saves the conguration changes, and returns to navigation mode.
