1.0 Introduction
1.1 Solinst Readout Unit (SRU)
The Solinst Readout Unit (SRU) is an in-field device designed to take and display instant water level readings from a
deployed Solinst datalogger.
When connected, you can also select a real-time sampling rate and start a real-time monitoring session independent of
the datalogger’s internal logging mode. Real-time logs can be saved in the SRU memory.
The SRU has a built-in barometer, which provides the option of showing and saving real-time water level readings
corrected to ambient air pressure.
The SRU also functions as a data download and storage device. It has a robust internal flash memory allowing you
to download and save multiple log files from a number of dataloggers. Saved log files can be viewed on the SRU and
transferred to a PC using Levelogger Software.
The SRU provides access to useful information about the connected datalogger’s status, including battery level, memory,
serial number, firmware version, and logging mode. You can also access information about the SRU status.

3.0 Connecting Dataloggers
3.1 Levelogger Connection
The SRU cable connects to the top of a Levelogger’s Direct Read Cable. Hold the Direct Read Cable connection
and thread the SRU cable connector onto the Direct Read Cable.
Figure 3-1 Levelogger Connection
Note: An L5 Threaded or Slip Fit Adaptor can also be used to connect a Levelogger to the SRU cable.
3.2 LevelVent Connection
The SRU cable connects to a LevelVent’s Wellhead. Hold the Wellhead and thread the SRU cable connector
onto the Wellhead.
Figure 3-2 LevelVent Connection
3.3 AquaVent Connection
The SRU cable connects to an AquaVent’s (App/DataGrabber) Wellhead Connector Cable. Hold the AquaVent
cable and thread the SRU cable connector onto the AquaVent cable.

4.0 Real-Time Readings
4.1 Take a Reading
Select Take a Reading to instantly display the current water level (water column height above the pressure
sensor), temperature, and conductivity being detected by the connected datalogger.
Note: Only LTC Leveloggers will display conductivity readings.
Note: See the Levelogger User Guide (Section 1.2) and Vented Dataloggers User Guide (Section 1.2) for an explanation of the
pressure sensor measurement fundamentals.
Figure 4-1 Take a Reading
The water level reading will indicate "Comp" as it is a compensated level reading. See Section 4.2 for more
details.
4.2 Barometric Compensation
Levelogger 5 dataloggers use an absolute pressure sensor, therefore, detect total pressure above the sensor
(water plus barometric pressure).
To eliminate barometric pressure and display water level only, select Next after taking a reading (Section 4.1).
Select to turn barometric compensation on. The SRU contains an internal barometer that barometrically
compensates the level readings. The barometer reading will be displayed on this screen.
Figure 4-2 Turn Barometric Compensation On/Off
LevelVent 5 and AquaVent 5 vented water level dataloggers use gauged pressure sensors, therefore, barometric
effects are already eliminated from the level reading through the vented cable.
Barometric compensation can be turned off in the same screen.

4.3 Real-Time Logging
The SRU allows you to select a real-time sampling rate and start a real-time logging session independent of the
datalogger’s internal logging mode.
Figure 4-3 Real-Time Logging – Compensation On
Figure 4-4 Real-Time Logging – Compensation Off
To set up real-time logging, after you have turned barometric compensation on/off (Section 4.2), select Next to select
the Sample Rate. The Sample Rate can be set from 2 seconds to 99 hours.
Select Start to begin logging. The level, temperature and conductivity readings will update at the specified sampling
interval.
Note: Only LTC Leveloggers will display conductivity readings.
At any time you can select to Stop and/or Save the real-time logging session. The real-time logs will be saved in the
SRU memory. See Section 5.2 to view the saved log files list and Section 7.2 to transfer files to a PC.

5.0 Downloading and Viewing Data Files
5.1 Download Logger
To download a datalogger’s current internal logging session, select Download/View Files from the main
menu, scroll to Download Logger and select Next.
The download progress will be displayed at a percentage. All data from the current logging session will be
saved in the SRU memory as a *.xle data file.
Note: An error message on the SRU screen will indicate when the memory is full. You can also view the status of the SRU memory
using the Statu/Status menu (see Section 2.5).
The file will be identified using the datalogger’s serial number and the date and time of the download.
Note: Downloading the data will not stop/interrupt the datalogger from logging. Datalogger memory will not be erased.
Figure 5-1 Download Logger
Note: *.xle files can be opened using Levelogger Software for further analysis and exported for use in other programs.
5.2 View Data Files
After downloading data from the connected datalogger, you can view a list of all the saved files on the SRU,
including real-time logging sessions, by selecting Download/View Files from the main menu then View Files.
The files will be identified as follows:
D = Downloaded Data File
C = Compensated Real-Time Data File
U = Uncompensated Real-Time Data File
