Specifications - Installation and Operating Instructions
Bulletin DA-DLP
The Series DLP is a data logger that can record pressure and
temperature. The 1/4˝ NPT fitting comes standard and allows the logger
to be adapted to almost any pressure fitting. The internal temperature
sensor provides accurate temperature measurements without the need
of a separate temperature recorder, and many of the models provide a
choice between measuring pressure in PSIA or PSIG. The DLP can
easily be started and stopped from a PC or delayed to start up to six
months in advance. The battery-powered data logger can store over
16,000 measurements per channel, and the easy to use DL700 software
makes retrieving data simple.

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.
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 5 through 1 in reverse order to complete installation.
MAINTENANCE
Upon final installation of the Series DLP Data Logger, no routine
maintenance is required. The Series DLP 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
