The OM-EL-HL is a low cost, hand-held EasyLog configuration and data
collection unit which can be operated by both technical and non-technical
personnel. The OM-EL-HL is designed to be used in environments where a
Windows based PC is either unavailable or impractical. Up to eight EasyLogs
can be configured and the data from each stored in non-volatile memory that will
hold the data until it can be analyzed on a PC.

A typical logging scenario consists of four stages:-

1.

Selecting and connecting an appropriate sensor.

2.

Choosing the desired recording method and starting the log.

3.

Stopping the log after the required period and extracting the recorded data.

4.

Presenting and analyzing the data.

The OM-EL-HL is operated by using a simple menu system. The Up and Down
arrow keys navigate the main/sub menus, while left and right arrow keys select the
appropriate logger. A “beep” will confirm that a key has been pressed.

The Enter key is used to select the highlighted menu.

The Escape key will revert to the previous menu without saving any data.

Arrow keys are also used in selected menus to allow the user to enter
alpha/numeric data.

Before operating the OM-EL-HL for the first time, two 1.5V AA type batteries
must be inserted correctly in the battery compartment on the rear of the unit. The
cover of the battery compartment is held in place by a single screw.

With the batteries in place, press the ON/OFF key to power up the OM-EL-HL.
The internal microprocessor clock will now need to be set with the correct time and
date. This is accomplished by using the Current Date and Current Time menus as
described on page 13.

The OM-EL-HL will also indicate a Low Battery Warning on power up if the
batteries have a low level of charge left. If this message is displayed, the user is
advised to switch off the OM-EL-HL and replace the batteries. The clock will then
require re-setting.

Once the clock has been set, the OM-EL-HL is ready to use.

When replacing the batteries, it is advisable for the user to wait approximately

N.B.

15 seconds before inserting the new batteries. This will allow the OM-EL-HL’s low
power circuitry to fully discharge.

Using the EasyLog interface cable (from OM-EL-WIN), plug the 9-way D socket
of the lead into the serial port at the top of the OM-EL-HL. The opposite end of the
lead is connected to the EasyLog. Depending on the module, the connector at this
end could be either a 9-way D socket, an 8-pin Mini-DIN or the jack plug supplied
with OM-EL-WIN-LITE.

Alternatively, the integrated InfraRed communication link can be selected in the
Comms menu. The InfraRed link may be used with OM-EL-PANEL-IR, OM-EL­LINK-IR or OM-EL-2-IR. OM-EL-LINK-IR can also be used for InfraRed
communication with a PC.
