Features

Indicators and Buttons

The data logger has only one button and one indicator. Both are located
on the front panel.

The button is used to start and stop recordings and to turn the data
logger on and off. The red LED indicates the status of the data logger;
OFF, STANDBY or RECORDING. When the LED is lit continuously it
indicates an Overload condition.

Inputs and Outputs

The left side of the data logger incorporates 2mm safety banana jacks
input connectors compatible with the current probes for which your data
logger was designed.

The right side of the data logger has a female 9 pin “D” shell serial
connector used for data transmission from the data logger to your
computer.

Mounting

Your data logger is equipped with clearance holes in the base plate tabs
for mounting. For less permanent mounting, the Velcro pads (supplied
loose) can be attached to the data logger and the surface to which the
data logger will be mounted.

8

Battery Installation

Under normal conditions, the battery will last up to a year of continuous
recording unless the logger is re-started very frequently.

In the OFF mode, the logger puts almost no load on the battery. Use the
OFF mode when the logger is not in use. Replace the battery once a
year in normal use.

If the logger will be used at temperatures below 32°F (0°C) or is
frequently turned on and off, replace the battery every six to nine
months.

1. Make sure your logger is turned off (no light blinking) and all
inputs are disconnected.

2. Turn the data logger upside down. Remove the four Phillips head
screws from the base plate of the data logger and take off the
base plate.

3. Locate the two wire (red/black) battery connector and attach the
9 V battery to it. Make sure that you observe polarity by lining up
the battery posts to the proper terminals on the connector.

4. Once the connector is plugged onto the battery, insert the battery
into the holding clip on the circuit board

5. Re-attach the base plate using the four screws removed in step
two.

Your data logger is now recording (LED blinking). Press the test button
for 5 seconds to stop the instrument

Note: For long term storage, remove the battery to prevent discharge
effects.

Operation

Connect the current probe to the Logger and position the probe around
the conductor to be measured. Make sure that the jaws are firmly closed
before beginning the recording session. (Probe output can not be more
than 1V AC for Model OM-SL-L100 and 1A AC for the Model OM-SL-

110).
Next, press the start/stop button on the front of the unit to begin the

recording session. The indicator light will double blink to indicate that the
recording session has started.

When the recording session has been completed, press the start/stop
button to end the recording. The indicator light will single blink to indicate
that the recording session has ended and the unit is in stand-by.

Unclamp the probe from the conductor and connect the Logger to the
computer for data downloading. See Section 2 page 19 of the main
manual for downloading.

2. From the Program Manager select “File” on the command line.

3. Select “Run” from the pull-down menu and type a:setup in the
dialog box then click on “OK”.

4. The set up program will temporarily load onto your computer.

5. Next the setup program will offer C:\DATALOG as location where
the software will be installed. Click on “Next” to use this directory or
type in a new name, then click on “Next”.

6. A bar graph will appear showing the progress of installation. When
installation is complete a message screen will appear stating that
the program has been installed. Click on “OK”. You are now ready
to use the data logger software.

Windows 95 Systems

1. Insert the floppy disk containing the data logger software in your
computer’s floppy drive (usually Drive A).

2. Click on the “Start” button on the bottom left side of the screen.

3. Select “Run” from the menu and type a:setup in the dialog box then
click on “OK”.

4. The setup program will temporarily load onto your computer.

5. Next the setup program will offer C:\DATALOG as location where
the software will be installed. Click on “Next” to use this directory or
type in a new name, then click on “Next”.

6. A bar graph will appear showing the progress of installation. When
installation is complete a message screen will appear stating that
the program has been installed. Click on “OK”. You are now ready
to use the data logger software.

USING THE SOFTWARE

Launch the software and connect the RS232 cable from your computer
from the logger.

Select “FILE”, “Baud rate” and “1200”, then select “PORT”, Com1, Com2,
Com3 or Com4 (see your computer manual). The logger must now
communicate with your computer (ID number of the logger and number
of points recorded displayed).

Select “FUNCTION”, then Logger L100 or L110 to choose your probe
ratio. Select download to display the graph. (Download takes about 90
seconds)

Function

The FUNCTION command allows you to select the correct engineering
units for the recorded data.

When you click on Function, a pull-down window will appear with all the
choices supported by the version of software you have installed. This
menu will only appear if a data logger is connected to the COM port.

Simply click on the desired group and then select the proper units from
the window that opens. Depending on which type of logger is connected,
the pull-down menu under Function may be empty. You will be returned
to the main screen and the graph Y axis scale will be recalculated using
the choice you made here.

Future downloads will use the units selected here for graphing as well.
The data logger communicates to the software its basic configuration.
Therefore, you will only be offered choices that are compatible to the
data logger.

Cleaning

The body of the clamp should be cleaned with a cloth moistened with
soapy water. Rinse with a cloth moistened with clean water. Do not use
solvent.
