Summary
Thank you for purchasing the new Analite NEP-695 long-life logging probe. It will give you years of service
if you install and maintain the probe according to guidelines set out in this manual.
The NEP-695 is an all-in-one device that contains a scriptable Serial Digital Interface SDI-12 logger with
an integrated rechargeable battery designed for long-term operations.
The system is housed in a fully water-sealed casing that can support up-to fifty meters of water pressure.
The NEP-695 is designed to fit with the NEP-5000 SDI-12 option, providing an optimised logging solution
to monitor the turbidity. The NEP-695 has a built–in 6-pin female SubConn connector as a sensor
interface. It provides the ability to connect multiple SDI-12 sensors into the same connector and monitor
multiple parameters.
When the NEP-695 is integrated with the NEP-5000 sensor, the following features can be obtained:
•Simple turbidity and temperature reading in auto-range (providing identical functionality as the Analite
NEP-495).
•Statistical measurement over a set period of time.
•Event logging through scripting (for instance if the turbidity or temperature is above 20NTU it will start
high-speed logging).
•Ability to connect multiple NEP-5000 sensors in multiple levels (data buoys).
•The ability to have a 90-degree NEP-5000 with 180-degree NEP-5000 sensor providing seamless
transition between drinking water monitoring to sediment monitoring.
•The option to add secondary SDI-12 parameters such as conductivity, PH and dissolved oxygen via
the SDI-12 bus (up to 9 sensors in total).
When using the battery on its own, with the NEP-5000 sensor, the system is capable of measuring 27,000
measurements. This is approximately five months in ten minute-intervals or indefinite use when connected
to a 20W solar panel. The main advantage of having a built-in rechargeable battery is that its low running
cost. Hence, users are not required to buy expensive batteries.
The NEP-695 is comprised of the Original Equipment Manufacturer (OEM) CR300 built-in logger by
Campbell scientific. This is a proven working solution by many Analite customers, which will provide a
scriptable logging capability.
Another advantage of using a scriptable logger is to increase the functionality of the existing probe adding
event logging, statistical logging, or using additional sensors.

6 Mechanical installation
6.1 Connect NEP-695 to a single NEP-5000
The following section describes how to connect a single NEP-5000 sensor to the NEP-695 logging probe.
Please proceed as follows in order to avoid damaging the NEP-695 connector:
•Firmly hold the NEP-5000 probe. Adjust the NEP-5000 male connector to fit the female NEP-695
connector.
•Turn the NEP-695 moving part clockwise to attach the logging probe to the NEP-5000 sensor. Always
loosely hold the NEP-695 moving part while firmly holding the NEP-5000 sensor (in order to avoid
damaging the NEP-695 connector).
The following block diagram represents the connection of the NEP-695 connected to a single sensor:

7 Charging & maintenance
7.1 Charge NEP-695
Follow these instructions to charge the NEP-695 logging probe:
1. To avoid any risk of water ingress falling onto the electronics, flip the probe up-side down, hold the
main body of the probe tight and unscrew the control lid off (make sure to let the water evacuate and
dry the lid completely). Undo the protecting cap from the logging probe by turning anti-clockwise until
turning has no-longer any effect. Then, firmly disengage the cap from the internal protective O-ring
(hear the click).
2. Charge the NEP-695 logging probe by placing the provided charging adapter into the centre pin and
apply power to the logging probe.
3. It will take on average eight hours to fully charge the logging probe from flat battery.
