VIII. Connecting to the Softwa re:
Important: This data logger supports an Auto Baud Rate Mode which automatically
detects the communication speed. Howev er ; this communication software also
supports loggers which may be programmed in a Fixed B aud Rate Mode. This is
useful in telemetry applications, par ticularly when using Global Water data loggers
with our Global Access radio modem soft war e. The upcoming discussion assumes
that the logger is programmed in auto det ec t mode. If you cannot connect to the
logger and suspect that the logger may be using a fix ed r ate mode; try each
connection speed separately, es pec ially 38400 which is required when using the
Global Access software. Direct connection is made through the USB port.
To connect to the logger, click the “Direct” option and from the “Port” menu, select
the USB serial port at the COM port the driver was assigned, which is automatically
shown in the list as “Global Logger USB Device”.
Next, select the desired baud rate fr om the “Baud Rat e” menu. Generally, the
recommended rate of 57.6K baud is used although; long cables or other factors may
require a slower setting. Click “Connect” to make the connection. If a connection is
not made, an error message will appear. Chec k the battery, communication cable,
driver installation and COM port settings.

COM Status: This reads “Connected” in green or “Not Connected” in red,
depending on the current connection st atus.
Logger Name: The logger name is a us er defined name associated with a particular
logger to identify one from another. It is progr am m ed in the Setup menu as
described later and is limited to 32 c har ac ters.
Logger Time: The time and date displayed is that of the real-time clock in the
logger. It is only updated upon initial connection and certain functions that caus e
data to be read from the logger. These include Sample Continuously, Get Sample,
Sync Time and Setup whose functions are to be described lat er .
Interval: This field displays the logging mode. “Fast” indicates high-speed mode
and “Logarithmic” is shown in logarithmic m ode. If the logger is in the normal fixed
interval sampling mode, the time between samples will be displayed. These modes
are to be described later.
Warmup: This displays the sensor warm -up tim e, generally 3 seconds.

Sample Continuously: Clicking this check box causes the Global Logger software
to take and display a real-time reading once per s ec ond until stopped by clicking it
again, as well as update the rest of the fields on the s c r een. These data readings
are not stored in the historical record and do not affect the normal recording of the
logger. The initial reading has a sensor warm-up time of 50mS and the sensor is left
powered up until this feature is turned off.
Get Sample: Clicking this button causes the Global Logger software to take and
display a single reading as well as update t he rest of the fields on the screen. This
data reading is not stored in the historical rec or d and does not affect the normal
recording of the logger.
Get History: This button starts the download of all the historical data stored in the
logger memory. Oldest data is collected fir s t and Clicking “Stop” halts the process.
This function is described in detail later.
Clear History: This resets the number of r ec ordings in memory to zero. The user is
warned first and must confirm the act ion before the memory is cleared.
Sync Time: This button causes the data logger ’s internal clock to be set to the
system time of the computer it is connected to. The user is warned first and must
confirm the action before the tim e is set.
Setup: Clicking this button enters the setup screen where the user can change and
program all parameters into the data logger. This function is described in detail later .
Bar Graphs: The bar graphs show a vis ual r epr es entation of the most recent data
reading taken by using the Sample Continuousl y or Get Sample functions. The
upper and lower limits of the display are defined by the user as discussed in detail
later.

Numerical Reading: The numerical reading at the bottom of the bar graph shows
the actual data reading and is updated at the s am e time as the bar graph.
Successive numerical readings taken by us ing S am ple C ontinuously or Get Sample
are shown in a list below the bar, up to 5.
Alarm 1: This field shows the time that the logger is s et to start logging. The start
alarm is a 24-hour timer which will initiate logging, when enabled, at the next
occurrence of that time.
Alarm 2: This field shows the time that the logger is s et to stop logging. The stop
alarm is a 24-hour timer which will halt logging, when enabled, at the next
occurrence of that time after the logger has st arted r ec or ding. If the Alarm 1 timer is
set to initiate logging, the Alarm 2 tim er will halt logging at the next occurrence of the
Alarm 2 time after the logger has been started by A lar m 1. If the Alarm 1 timer is not
enabled, the Alarm 2 timer will halt the logger on t he nex t occurrence of that time.
Note: The alarm start and stop cycle is a one time occurrence. Once stop ped
by the Alarm 2 timer, the logger will not resume logging again until the logger
is reprogrammed. Reprogramming the logger with the timers enabled will
restart the alarm cycle. Reprogramming t he logger with the timers disabled
will return the logger to a normal logging state
Use care when programming the alarm times. If l ef t enabled, changing and
reprogramming any of the setup parameters wi ll rest art t he alarm timers and
could cause the logger to stop recording.
Using the Alarm 2 Stop Timer can significantly in crease battery life, especially
when using fast sampling speeds. See section XVIII for more information on
battery life.

XI. Get History:
Clicking the Get History button begins the downloading of the historical data into an
information screen. This screen allows the viewing of the recorded data and also
provides a path to export the data to an Excel compat ible file (.CSV file). Note that
the logger continues to log as data is download ed. Thus, more data points may be
downloaded than originally indicated.
At the top of the screen is shown the name assigned to t he logger and the number of
recordings that have been retrieved. A t t he bottom of the screen are three buttons,
Pack, Save to File and OK.
Pack: The Pack function removes recordings that are identical to the previous ones.
All the channels must be the same as the row above for it to be rem ov ed. If ev en a
single channel has data that differs from the previous sample, the row will not be
removed. This function works best when a single c hannel is being r ec orded and
allows only the data showing changing conditions to be viewed.

to default values. Only the setup
menus are changed, the data logger
must still be programmed with the
new default values. A warning message will appear before this action is taken.
Help: The Help menu provides access to the on-line help files and Global Water
contact information as described previous ly .
XIII. General Setup:
In the General Setup menu, the logger name, sensor war m -up time, logging mode,
logging interval and alarm times ar e entered.
- 17 -
Global Water
800-876-1172 • globalw.com
Name: The logger is a user definable name to identify the logger. Up to 32
characters are allowed however, a cont inuous s tring of characters of more than 16
with no spaces may not be displayed correctly . Click on the field to enter
information.
Sensor Warm-up Time: To conserve battery life, the
sensor does not normally have power applied to it.
Before taking a reading, the logger powers up the
sensor for the sensor warm-up time, and then rem ov es
power from them again. A warm-up time of 0 seconds
is recommended. Click on the field to enter or select
the time in seconds from the pull-down menu.
Baud Rate: Leave this set t o A uto Baud Rate.
Only change this to a fixed baud rate if planning t o
use this logger in a telemetry application, such as
using Global Water’s Global Access radio m odem
software. Once programmed in a fixed rat e mode,
you must set the baud rate in the opening connect ion menu of the Global Logger II
software to this speed, or the logger will not communicate.
Sample Periodically: Sam pling at regular intervals is the most common recording
mode. Click the Sample Periodically option, s elect the units from the pull-down
menu and click the numerical field to enter the number of those units up to 65,535.
Fast Sampling Mode : In Fast mode, the sample rate is fixed at 10 times per
second. The time stamp will not read fractions of a second so there will be 10
samples per time stamp. Click the Fast m ode option t o s elec t this feature.
- 18 -
Global Water
800-876-1172 • globalw.com
Logarithmic Timing: Typically used in groundwater pump studies, this mode
speeds up the sample rate over time. Click the “Logarithmic” option to select this
mode. This is a logarithmic approximation that steps up the sample rate:
a. 10 times per second f or 20 seconds , 200 samples
b. 1 second interval for 100 s ec onds , 100 samples
c. 10 second interval for 10 minutes, 60 s am ples
d. 1 minute interval f or 60 minutes , 60 samples
e. 10 minute interval f or 10 hours, 60 s am ples
f. 1 hour interval for 48 hours, 48 samples
g. 1 day interval until memory s full
Log Upon Deviation: Clicking the “Log only if Channel 1 change exceeds +/-“ box
causes the logger to record the current r eading in m emory only if it exceeds the
previously reading by the preset am ount entered in the numeric field. This logging
exception applies to channel 1 only and the deviation is measured in Raw Data units
where the approximate raw data range is f r om 0-65535, cor responding to 0-20mA.
To find the actual number of raw data unit s per engineering unit, use the calibration
numbers in the Analog Setup screen for c hannel 1 as follows : Raw Data Units per
Engineering Unit = (High Raw – Low Raw) / (High EU – Low EU) . For example: The
PL500G has a High EU of 100, a Low EU of zero, a High Raw of 34874 and a Low
Raw of 7846. (34874-7846) / (100-0) = 270.3 raw data unit s per ps i. Thus, if you
want to log only when a reading exceeds the previous on by 10 ps i, set the deviation
to 2703. Click the numeric field to enter the desired range.
Wrap records: If the “Wrap records at End of Storage” box is chec k ed,
once the memory is full, the oldest data points will be replaced with the newest.
Thus, the memory block represents only the newest. If this feature is not checked,
the logger will halt recording once the memory is full.

Global Water
800-876-1172 • globalw.com
Sample-On-Demand: This feature is not supported by the PL200H data logger.
Alarm Times: Check the box
associated with each alarm to
enable that feature and enter
the desired start or stop time.
The logger will start at the next
occurrence of the Alarm 1 time and stop at the next occurrence of the Alarm 2 time
after the Alarm 1 timer has expired. Either or both alarm s c an be enabled.
Important:
These timers are a one time event; the logger wi ll no t restart on th e next
occurrence of the Start timer unless th e logger i s reprogrammed with these
settings.
Use care when programming the alarm times. If l ef t enabled, changing and
reprogramming any of the setup parameters will restart the alarm timers and
could cause the logger to stop recording and the loss of important data.
Using the Alarm 2 Stop Timer can significantly increase battery life, especially
when using short sample intervals. See section XVIII for more information on
battery life.

Analog Setup:
The Analog Setup screen sets the engineering units and c alibr ation numbers for
each of the analog channels, the endpoints of the bar graphs in the main screen and
which of the analog channels are enabled. These channels ar e c alibr ated in the
same way so a single channel will be discussed.
information stored in the data logger’s memory is just the sensors output level before it is
adjusted by the following calibration parameters. These parameters are used to adjust the
stored data for display and storage purposes only, at the time the data is downloade d. If
they are changed, the same stored data can be downloaded again and the data will be
scaled differently according to the new settings.
It is important to note here that the
The PL200H Logger comes factory calibrat ed but you may want to re-calibrate on
occasion. The pressure sensor is designed to m eas ur e ov er the range of 0-200 psi
but it can be calibrated at lower pressures. The screen above s how s c hannel one
calibrated at 100 psi but set to display up to 200 ps i on the main screen.

Global Water
800-876-1172 • globalw.com
Enable: If the “Enable” box at the top of a column is checked,
data for that channel will be shown in the hist or ic al r ec or d and
be available for export to Excel. The dat a
for all the analog channels is always being
recorded whether the channel is enabled
or not.
Units: This field shows the units that will
appear at the top of the data column for
that channel in the historical record as well
as the display of data in the main screen.
Click on the field to enter the unit or select
from a predefined list. Note that psi is not included in t his lis t.
High EU: The High EU field is the engineering unit where the
highest output from the sensor is achieved during the calibration process, in this
case a pressure of 100 psi.
Low EU: The Low EU field is the engineering unit where the lowest output from the
sensor is achieved during the calibrat ion pr oc ess, in this case a pressure of zero.
High Raw: This is the raw data value as measured by the data logger that
corresponds to the High EU value and is automatic ally s et by the calibration process.
In this case, the raw data value returned by t he logger at a pr es s ur e of 100 psi.
Low Raw: This is the raw data value as measured by the logger that corresponds to
the Low EU value and is automatically set by the calibrat ion pr oc es s . In this case,
the raw data value returned by zero pressure.
Disp High: This field sets the upper limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the upper limit used to
calibrate the logger. In this example, the upper calibration point was a pressure of
100 psi but the maximum range of the sensor is 200 psi.
Disp Low: This field sets the lower limit of the bar graph displayed in the main
screen and provides a way of scaling the graph beyond the lower limit used to
calibrate the logger. In this example, the lower calibration point was at zero psi.

Decimal Places: From the pull-down menu, select the
number of decimal places to the right of the decim al
point that should appear in the histor ic al data and in the
numerical data field at the bottom of the bar gr aph.
Calibrate: The “Calibra te” button provides a simple 4-step process for calibrating
the logger to a particular sensor. Click t he C alibr ate button and follow the menu
instructions.
Click on the High EU field and enter the
high engineering unit that will be used t o
calibrate the logger, not the highest r eading
the sensor can output. In this example, a
pressure of 100 psi is used to calibrate
the logger, even though the sensor c an
measure up to 200 psi.
Click Next.
Place the sensor in the condition that will
cause it to output the level corresponding
to the high EU entered in the previous menu.
Wait for the data reading to stabilize.
Click Next.
Click on the Low EU field and enter the
low engineering unit that will be used
to calibrate the logger, not necessarily
the lowest reading the sensor can output .
In this example, the value is zero psi.
Click Next.
Place the sensor in the condition that will
cause it to output the level corresponding
to the low EU entered in the previous menu.
Wait for the data reading to stabilize.
Click Next to complete the calibration.

immediately. If settings have
changed but not saved yet,
a message will appear that
asks the user if they would
like to save them now. If the
settings have changed but
not yet programmed into the
logger, another message will
be shown asking if the logger should be reprogram med. These layers of
protection are designed to prevent the user from unintentionally changing
settings or forgetting to save the configuration file. Should the settings
accidentally be changed, a saved configuration file can be loaded and used to
restore the original settings.

XV. Installing t he Data logger
The data logger is an electronic device and sensi t ive to excessive mechanical
abuse. Do not drop the logger or otherwise subject it to mechanical shock.
The assembly can be heavy and could do significant damage to the logger
housing if handle d im pr ope r ly.
Do not hammer the prongs to tighten the
logger onto the hydr ant, only use a spanner
wrench of appropriate size and turn the logger
carefully as it is tighten or is removed.
Do not twist the logger housing.

XVI. Battery Replacement:
Except for the battery, there are no user-servic eable par ts inside the PL200H Data
Logger. Global Water recommends check ing the batteries every 6 to12 months, or
when the battery voltage monitor shows a low voltage c ondition of 3.4 volts or less.
To change the battery; turn the thumbs c r ew in the center of the top cover counterclockwise and remove it. Remove the 3 scr ews holding down t he c r os s bar .
Replace the battery with a 3.6 volt AA size lithiu m battery only, AA size
batteries commonly used in consumer el ectro nics only produce 1.5 volts and
will not operate the data logger. Be careful to observe t he polarity, align the
battery as shown. The high capacity batter y described in the specifications section
is recommended. Replace the crossbar , making sure that the cutout on one side is
properly aligned with the USB port .

XVII. Battery Life
The 3.6 volt lithium battery may last 2-3 years, depending on use; however, higher
sample rates can reduce battery life significantly. It is impossible to accurat ely
predict the battery life for all types of usage and conditions, such as sample rate and
ambient temperature; however a general assumption is that a new battery will last
about 1-2 years based on continuous use at sample r ates of 1 minute or greater, and
normal ambient temperatures of at least 32ºF.
One of the best features of the PL300H Hydrant Logger is the 10 times per second
sample rate. This feature allows you to capt ure detailed data from pressure waves
cased by water hammer and other affects, but it also consumes the most power.
Under normal conditions, this feat ur e w ill deplete the battery in about one week if left
turned on.
You can increase the battery life significantly when using the high sample rate
mode by utilizing the alarm start and stop timers, as des c ribed on page 13. In
high speed mode, the memory will hold 81,759 data points or 2 hours and 16
minutes of data; which usually makes it im pr ac tical to keep the logger running any
longer than that. Use the alarm start and stop timers to record data and fill memory
only when data needs to be collected. How the memory w r ap-ar ound feat ur e
described on page 19 is set determines whether the first 81,759 accumulated data
points are stored or the most recent ones . Wit h wrap-around t ur ned off, the logger
will continue to take readings and consume po w er , the data is just not stored in
memory once it is full. Thus, turning m em or y wrap-around off will not save power.

XVIII. Troubleshooting:
Issue: Logger is reading incorrect ly .
a. Verify the battery has enough voltage. To operate properly, the logger
must have about 3.3volts or more. If the batt er y voltage monitor is
reading less than 3.3 volts or seems incorrec t, check the batteries with
a voltmeter or replace them. Batter y v oltages less than 3.4 volts
indicate that the batteries need replacing soon.
b. Check the logger and sensor c alibr ation numbers in the Setup Menu.
Recalibrate the logger if necessar y . As a precaution, save the setup
file first as described in section XII.
Issue: Cannot communicate with t he logger .
a. Verify that a fres h batt ery is ins talled.
b. Check the communication cable.
c. Use the Device Manager to confirm that the dr iver is loaded and the
correct virtual COM port is select ed in the connection menu of the
Global Logger software. Check the D ev ic e Manager in your oper ating
system and confirm that the USB COM port is not being used by
another device.
d. Try reducing the baud rate in the connection screen of the Global
Logger software. Try each baud rate sett ing in case t he logger has
been programmed in Fixed Baud Rate mode.
Issue: Logger is not recording.
a. Check if the A lar m 2 Stop Tim er is s et. The status of the logger can
be seen in the top right corner of the Global Logger II m ain s creen. If it
says Stopped by Alarm 2, you must reprogram the logger.
b. Check the Memory Wr ap-Around f eature. If this setting is off and the
logger’s memory is full, no further logging will occur until the feature is
turned on or the memory is erased.
c. Check the battery for proper voltage.
