1. OVERVIEW
The MICRO-800 Datalogger is designed to support the reading of a large number of Geokon
Vibrating Wire Instruments for various unattended data collection applications through the use of
an internal Geokon Model 8032 Multiplexer. Weatherproof packaging allows the unit to be
installed in field environments where inhospitable conditions prevail. The Nema 4X enclosure
also has a provision for locking to limit access to responsible field personnel.
A basic datalogging system consists of the Campbell Scientific CR800 datalogger, an internal
multiplexer and an External Multiplexer port. Multiplexers expand the system by increments of
16 or 32 channels depending on the instrument type and configuration. The standard model
8025-2 Micro-800 datalogger can support one internal Multiplexer and external Multiplexer. The
External Multiplexer port can also be used to Daisy chain up to eight Multiplexers (please see
8032 Manual for more information). The standard model 8025-4 and 8025-5 dataloggers are
identical to the model 8025-2, but are configured for 32 VW gages only (8025-4) or 32
Thermistors only (8025-5). The standard model 8025-3 Micro-800 datalogger can support two
internal 16 channel Multiplexers and has 32 cable entries.
2. HARDWARE
The controller portion of the MICRO-800 datalogger consists of a Campbell Scientific CR800
Measurement and Control Datalogger. To gain an understanding on the workings and
capabilities of the CR800 it is necessary to read the Overview section of the CR800 Operator’s
Manual. The CR800 Operator’s Manual is available as a pdf file on the Campbell Scientific
Resource CD supplied with the datalogger.
A Campbell Scientific AVW200 Vibrating Wire Interface provides the required excitation and
signal processing for the vibrating wire sensors connected to the Datalogger. The AVW200 uses
spectral analysis to find the resonant frequency of the Vibrating Wire Gage. The AVW200 is
also used to measure the thermistor used in Geokon’s vibrating wire instruments. For complete
specifications of the AVW200 see the AVW200 Instruction Manual on the Campbell Scientific
Resource CD.
A dual-mode battery charging circuit board is used to provide the charging voltage for proper
maintenance of the installed lead acid battery. The circuit board contains fused protected
terminal blocks used to provide a nominal 12VDC supply for devices such as the CR800 and
Model 8032 Multiplexer board. In some cases a Solar Charge Regulator may be used in place of
the dual-mode charger.
The Model 8032 Multiplexer board expands the number of channels that can be read by the
MICRO-800 Datalogger. The channel switching is accomplished by mechanical relays mounted
on the underside of the circuit board and the transducer connections are accomplished by friction
locking terminals. Power, reset and clocking for the multiplexer are supplied by the MICRO-800.
The Model 8032 multiplexer can be configured for 16x4 or 32x2 channels depending on
application. Please see Appendix F for more information on the Geokon Model 8032
multiplexer.
A 12 volt, seven amp hour, lead acid battery is used to provide power for the datalogger. The
battery is provided to supply operating power for a limited period of time should the AC or solar
power, used to maintain the battery, be interrupted. Under normal operating conditions and
proper maintenance, the life expectancy of the battery is approximately five years.

3. INSTALLATION
The recommended method of installation involves attaching the enclosure (MICRO-800) to a
fixed structure, such as a wall, in an upright position (Figure 1). Mounting dimensions shown in
inches:
Figure 1 - Dimensions
3.1 Turning on Power
After the Datalogger is installed the charger can be plugged into the AC mains and the On/Off
switch S1 on the Charge Regulation circuit board switched to the “On”position (Figure 2). It is
recommended that the charger be left plugged in at all times (Section 5.1).
Figure 2 - Charge Regulation Circuit Board

3.2 Earth Ground
An earth grounding lug is supplied on the exterior of the Micro-800 enclosure to connect the
system to earth ground (Figure 3). A grounding rod can be driven (or other suitable attachment to
earth utilized) to ground the system and provide a path to earth for protection against a lightning
strike or other transient voltage. A 6’to 8’copper grounding rod connected to the Dataloggers
grounding lug with a large gauge wire (12 AWG or larger) is recommended. The earth ground
connection should be made as close to the Datalogger as possible.
3.3 Gages
At this time the vibrating wire sensors can be connected to the multiplexer. Please refer to
Appendix F for the appropriate connection description.
3.4 Communications
Standard communications with the Datalogger is established by connecting the supplied serial
cable to the RS-232 port (Figure 3) and the COM port on a computer, or a USB port on the
computer by using the provided USB to Serial converter cable.
Figure 3 - Datalogger Connections
4. SOFTWARE
The Micro-800 Datalogger is operated by a download file that is generated by a software
program. The software package the MICRO-800 Datalogger may be supplied with is either
MultiLogger software (developed by Canary Systems, Inc., New London, NH) or LoggerNet
software (developed by Campbell Scientific, Logan, Utah). Please refer to the manual supplied
with the software for instructions on installing the software and creating the required download
file for datalogger operation.

5. BATTERY MAINTENANCE
5.1 AC Power
The MICRO-800 is supplied with an external AC to DC power supply for maintaining the charge
of the battery and providing power to the Datalogger and peripherals. It is imperative that the
power supply remain connected to the Datalogger as the battery installed in the Datalogger is
only provided as a temporary source of power should the power supply be disconnected or mains
power interrupted. Actual run time solely on battery power will vary for each datalogging
system, depending on the hardware configuration and sensor scan interval. If the battery voltage
drops below 9.6 volts operation of the Datalogger will become erratic as evidenced by
communication problems and possible improper measurements.
5.2 Solar Power
If AC mains power is not available, a properly sized solar panel can be used to provide power to
maintain the charge state of the battery and provide power to the Datalogger and peripherals. The
size of the solar panel is determined by geographic location of the Datalogger, hardware
configuration, and the sensor scan interval.
5.3 External Battery
Additionally, a large external battery, such as a deep cycle marine battery, may be connected to
the Datalogger via the supplied external power cable to provide power to the Datalogger and
peripherals. When this type of battery is connected to the Datalogger the internal Datalogger
battery is automatically disconnected from the system to prevent parasitic drain on the external
battery.
5.4 Battery Replacement
If the internal Lead Acid Battery has failed it is recommend that the unit be returned to the
factory for service by Geokon personnel. However, with skilled personnel and appropriate tools,
it is possible for the user to replace the battery. Consult the factory for information.
5.5 Fuses
There are five fuses on the dual mode charger board of the MICRO-800 (Figure 2). Once
removed and with the power switch off, a fuse can be checked visually and with an ohmmeter. A
gap may be evident (with some discoloration) if the fuse needs replacing. This can be verified by
a high resistance measurement (megaohms) with an ohmmeter. If fuse needs replacing, insert
one of the supplied replacement fuses. If there are no replacement fuses available, consult the
factory or they can be purchased from an electrical supply house. All five fuses are two amp
SLO-BLO 5x20 mm. Consult Appendix D.7 for fuse assignments.

6. TROUBLESHOOTING
This section will NOT attempt to cover all possible problems that could be encountered in the
course of Datalogger operations. Consult the factory if other problems arise or remain
unresolved.

Cannot communicate with the Datalogger.
Suggestions:
1. The wrong communication cables are being used or the cables in use are defective.
Consult Appendix D.3 to verify cable pinout. Consult the factory for interfacing information.
2. The internal battery could be dead. Charge overnight and try again. If it still doesn’t work
check the voltage across the terminals of the battery. If the voltage is still below 10 volts the
battery may need to be replaced.
3. The wrong communication port is being used on the host computer (default is COM1).
Consult the appropriate software manual for instructions on changing the communication port.
4. The communication port on the host computer is defective. Verify the functioning and
configuration of the COM port by using it with another RS-232 device, such as a modem or
serial printer.
5. The Datalogger Auxiliary Fuse on the Dual-Mode Charger board is blown. Refer to
Appendix D.7 for proper fuse replacement.

The system battery voltage and panel temperature read odd numbers.
Suggestions:
1. The system battery could be low. Charge and check again (see previous section).
2. A disruptive current loop may be operating as a result of improper grounding or
excessive noise. Consult the factory for more information.

The internal battery measurement does not increase and charging LED (Yellow =
Charging and Green = Charged) does not light when the AC adaptor is plugged in.
Suggestions:
1. The adaptor may be damaged. Check the output pins of the adaptor with a voltmeter.
2. The charger fuse is blown. Consult Section 5.5 for checking and/or replacement.
3. The internal battery is no good. Consult the factory.

6

The Datalogger will not operate on external power.
Suggestions:
1. The external voltage supply is below operating limits. If the external source is a battery,
charge it. If it’s a power supply, check the output with a voltmeter.
2. The external power or battery fuse is blown (Section 5.5).

Loss of CR800 program and/or data.
Suggestions:
1. The system has experienced a voltage dropout or surge which disrupted operations.
2. The surge originated as a result of lightning. Install appropriate grounding. Install
lightning protection devices on all incoming and outgoing lines (consult factory).

Sensor readings show -99999 or are unstable.
Suggestions:
1. The wrong sensor type has been selected. Check the model number of the sensor against
the software setting (Section E.1).
2. The cable(s) to the sensor(s) have been damaged permitting moisture and debris to enter
the jacket. Wires may be shorted together. Inspect the cable.
3. If all sensors on a particular multiplexer are erratic or returning “-99999”perhaps the
multiplexer or interface cable has been damaged / unplugged.
4. The sensor(s) have been damaged. For example, overrange on a vibrating wire sensor can
cause erratic readings.
5. There is an electrical noise source nearby. Move the sensor, cables, and Datalogger away
from the noise source. Install grounding devices. Consult the factory.

The sensor readings show OVERRANGE all the time.
Suggestions
1. The “Sensor Type”selected for that particular channel is “None”. This is applicable for
users of MultiLogger (Section E.1). Please refer to the MultiLogger manual.
2. A scan has not been initiated yet because of the “Start Time”setting (MultiLogger users
only).
3. “Update”has not been run (MultiLogger users only).

APPENDIX E. LOGGERNET QUICK START GUIDE
E.1 Overview
Campbell Scientific’s LoggerNet Software is used to communicate with the Datalogger, program
user specific settings and collect Data stored in the Datalogger memory. LoggerNet is designed
to be used with Geokon Micro-1000 and Micro-800 Dataloggers reading Vibrating Wire and
MEMS tilt sensors. Other configurations and sensor outputs are available upon request. Geokon
provides the user with a generic Start Program to simplify acquiring Data without the need to be
proficient in Campbell Scientific CRBasic programming code. The Start Program(s) will be
preconfigured with a default Scan Interval and will store Raw Units by default. Each Start
Program will have two associated files on the factory supplied USB flash drive. The first is the
Main CRBasic program (.CR1/.CR8) and includes all programming code required to read and
store Data according to the Datalogger configuration. The Main CRBasic program does not
require modification by the user in most cases. The second file is the Include (.DLD) text file and
is used by the Main program to import user specific parameters. The Include File allows program
parameters such as the Scan Interval, Zero Readings, Linear Gage Factors, Data File Header
Labels and Temperature Correction factors to be modified by the user.
E.2 Getting Started
E.2.1 Program Files
After installing LoggerNet, the CRBasic program files are located on the Geokon USB
Thumb Drive. The file types are “.DLD” and “.CR1”/“.CR8.”, these files should first be
copied to the end users computer in C:\Campbellsci\CRBasicEditor.
E.2.2 Connection Setup
The Launch Menu provides a drop-down list of all the categories on the LoggerNet
toolbar. Hovering over a category will display a list of applications related to that
category.
With the Launch Menu open, hover over “Main” and press “Setup” from the resulting list
of applications.
