CONNECT THE LOGGER

1. Remove the Warning sticker from the USB Data Logger Interface
converter to uncover the female end of the jack.

2. Insert one end of the jack into the USB Data Logger Interface
converter and the other end into the serial port in the data logger.

3. The serial port is located under the cap that has the key ring hole.
Unscrew the cap and connect the cable.

4. Connect the DL700 USB cord to the PC and connect the other end
to the USB Data Logger Interface converter.

START THE LOGGER

1. To start the logger, from the Communication menu select Auto
Configure Port.

2. From the Device menu select Start Device and choose the desired
Reading Rate.

3. Click the Start button.

NOTICE

Starting the device erases all data currently stored in the logger.

4. The logger will stop recording when the device is full or when Stop
Device is selected from the Device menu.

DOWNLOAD DATA

1. To download data, connect the logger to the PC.

2. Select Read Device Data from the Device menu.

3. Data is then presented graphically.

*For more detailed information on using the DL700 software, please
consult the Software Manual.

HUMIDITY SENSOR

If the optional humidity sensor model is purchased, unscrew the humidity
cap enough to allow the humidity sensor vents to allow air in. The
humidity cap is fully unscrewed when the cap becomes difficult to turn.
Make sure that the humidity cap is screwed on as tightly as possible
before the logger is submerged. The humidity will not be measured if the
device is submerged.

3. Once the snap-ring has been removed, press gently on the white
disk to force one end up for easy removal.

4a. For the Model ISDL-T10, gently slide the circuit board from the metal

case.

4b. For the Model ISDL-R10, use a non-slip grip to unscrew the middle

section that is directly below the humidity cap. Carefully pull on the
edges of the green, disk-like circuit board to slide the circuit board
from the metal case.

5. Set the circuit board down and make note of the orientation of the
battery’s positive (+) terminal. The “+” indication is also on the circuit
board.

6. Remove the old battery and install the new battery noting the
orientation of the positive (+) terminal.

NOTICE

Depending on where you purchased the battery, the leads may not be
bent correctly or at all. Follow the diagram below for bending the battery
leads properly.

BATTERIES

Typical battery life is 1 year. Fast logging will considerably shorten the
battery life. To preserve battery life, it is recommended to use the longest
practical sampling rate, and when the logger is not in use, select Stop
Device from the Device menu.

BATTERY REPLACEMENT INSTRUCTIONS

1. Remove the end cap with the key ring hole in it, revealing the serial
port.

2. Remove the snap-ring with snap-ring pliers.

8. Repeat steps 4 through 1 in reverse order to complete installation.

MAINTENANCE

Upon final installation of the Series ISDL Data Logger, no routine
maintenance is required. The Series ISDL is not field serviceable and
should be returned if repair is needed (field repair should not be
attempted and may void warranty). Be sure to include a brief description
of the problem plus any relevant application notes. Contact customer
service to receive a Return Goods Authorization number before
shipping.
