1.0 OVERVIEW
• The main display screen will appear (see Figure 1
as example). The information displayed includes a
(user selectable) primary parameter (larger number)
and a secondary parameter (smaller number) as
selected by the user.
• To view all channels on the same screen (alternative

1.4 CALIBRATION
All TGP measurement systems come precalibrated
from the factory. Calibration is generally not necessary
and should only be undertaken if sensor readings
appear to be incorrect. There are three sensors: two
pressure sensors [TGP (mmHg), BP (mmHg)] and one
Temperature sensor (degC).

TGP PRB
To check the calibration of the pressure sensors (BP),
obtain a reading of the barometric pressure from the
local weather ofce (convert to mmHg using Table
3) and compare it to the sensor reading. Note that
weather ofce readings are usually referenced to
sea level, therefore altitude compensation may be
necessary.
When checking or calibrating the TGP reading, leave
the TGP probe in air for a minimum of 10 minutes
to allow the pressure to equilibrate with atmospheric
pressure. Once the probe is dry, continue with the
following procedures.
• Press “MENU” and use the arrows to select
“CALIBRATION”. Press “ENTER”.
• 3 choices will appear on screen: “TGP mmHg”,
“Temp DegC”, and “BP HH mmHg”. Use the
arrow keys and “ENTER” to select the appropriate
measurement calibration.
• Use the arrow keys to highlight “1 Point Cal” and
press “ENTER” to begin.
• Use the arrow keys to manipulate the sensor reading
and press “ENTER” to accept the reading (after
each calibration) and complete the calibration. The
mV sensor reading is for diagnostic purposes only.

Calibration Sequence:
1. Calibrate the Barometric Pressure (BP) using the
value in mmHg obtained from the local weather
ofce (modied according to altitude). Press
“ENTER”.
2. Calibrate the TGP using the same value as used for
the BP. Press “ENTER”.
3. Calibrate the Temperature if needed. Press
“ENTER”.
TEMP 2PT. IN WATER BATH
Due to inherent limitations common to all TGP
probes, the probe must be periodically removed
from in-situ measurement and dried completely
prior to calibrating. In most cases this should be
done once every 3 weeks. If the probe is used in
water with temperatures above 20 degrees C,
this should be done more frequently than every
3 weeks.
NOTE: A “2 Point Calibration” is generally unnecessary
and should not be undertaken without rst consulting
Pentair Aquatic Eco-Systems Technical Support.

A free alternative to the Original HyperTerminal is
Putty, which can also be found online, this program
has a different look and feel to HyperTerminal and may
require different set of steps in order to achieve the
same results. Use the steps listed in this manual as
an overall guideline to what is required to connect to
the Tracker, but refer to the Putty manual specically
to achieve the desired result.
1.15 INSTALLING DRIVER
Step 1: Plug the USB to Serial Converter into you PC.
Step 2: Windows will automatically search for the
appropriate drivers.
Note that you may need to be connected to the
internet for this process to complete.
1.16 CONFIGURING COM PORT SETTING
Step 1: Connect USB data cable to your PC. Do not
connect it to the Tracker yet
Step 2: Press the [START] button.
Step 3: Right click [Computer] and select [Properties].
Step 4: From the Properties window select
[Device Manager].
In the Device Manager locate
[Port (COM & LPT)].
1.14 INSTALLING HYPER TERMINAL
HyperTerminal is only included on Windows machines
that are running Windows XP and is no longer
available In Vista, 7, or any later version.
If you need HyperTerminal in one of these later
versions of Windows you can actually extract two
les from your XP installation and copy them over to
your Windows installation.
The two les you will need are hypertrm.dll and
hypertrm.exe.
You should be able to nd hypertrm.exe in C:\Program
Files\Windows NT and hypertrm.dll in C:\ Windows\
System32.
If you have the Windows XP CD, you should be able
to nd both of these les in the i386 directory on the
CD.
Step 1: On the Windows 7 PC create a new folder
under C:\Program Files\HyperTerminal for 32-bit.
For 64-bit PC, create a new folder C:\ Program Files
(x86)\HyperTerminal
Step 2: Copy both les to that folder (hypertrm.exe
and hypertrm.dll)
Step 3: Now you can run the program by clicking on
"hypertrm.exe".
Step 4: If you want to have HyperTerminal on your
Start Menu just create a shortcut to hypertrm.exe and
put it in C:\ProgramData\Microsoft\Windows\Start
Menu\Programs and when you go to All Programs
under the Start
Menu Hyper Terminal will be there (you might have to
rename the shortcut).
If you do not have access to the original HyperTerminal
or an XP installation you can still use alternative
programs.
The most common alternative is HyperTerminal
Private Edition which is a commercial emulation
program that can be found online with a free trial. This
successor to the original HyperTerminal functions
the same way and can use the same instructions as
outlined for HyperTerminal.

2.2 CONTINUOUS USE
In some applications the TGP probe is left continuously
submerged in water. Under such circumstances,
eventually water condenses as small droplets on
the internal walls of the tubing. As these droplets
grow in size, they will eventually coalesce resulting
in “cross-bridging”. The pressure detected by the
sensor will produce a difcult-to-dene average of
the actual TGP. Cross-bridging can lead to excess
water accumulation inside the tubing.
Excess water in the tubing can damage the pressure
transducer if actual contact is made with the pressure
sensitive wafer.
The time taken for such a condition to arise is
inversely proportional to water temperature. i.e: the
higher the water temperature, the faster the bridging
will occur.
In summary, the frequency of probe maintenance is
site and condition specic.
AS A GUIDELINE, THE PROBE SHOULD BE
REMOVED FROM THE WATER ON A ROUTINE
BASIS EVERY THREE WEEKS FOR CLEANING.
(based on water temp of 15Deg C)
*Refer to section NORMAL PERIODIC USE for
maintenance procedures.
2.1 NORMAL PERIODIC USE
After each measurement session:
• Remove the probe from the water, rinse clean
straight away before any form of fouling dries on
the membrane tubing.
• Slide off the protective tubing shield.
• Rinse off the membrane tubing with clean fresh
water and gently shake the probe dry.
• Allow up to 4 hours for the probe to dry out (*more
time might be required in cold damp environments).
• Store dry at room temperature.
• If time is of the essence, have a spare cartridge
available, and swap out the cartridges.

Step 1:
CAREFULLY unscrew the membrane cartridge from
the probe body. Be careful not to damage or stress
the ne membrane tube, which connects to the
pressure sensor in the electronics housing.
Step 2:
Pinch the head of the membrane tube; carefully
separate the membrane tubing from the sensor port
and set the now completely detached membrane
assembly aside.
NOTE: ENSURE THAT INNER SILASTIC TUBE HAS
NOT COLLAPSED! SEE IMAGE BELOW.
2.3 A SIMPLE CHECK FOR A DAMAGED
OR BROKEN MEMBRANE TUBE
If the membrane tube is compromised in any way,
TGP readings will be wrong. A simple way to check
the integrity of the tubing is to observe the TGP
readings as the probe is steadily immersed in water. A
fast increase (several mmHg per second) in displayed
values indicates a damaged or broken membrane
tube. Replace the cartridge and recalibrate.
The recommended method to check for a faulty
membrane cartridge is to use the syringe test as
shown on the following page.
• Inspect the tubing for any visible signs of damage.
If damaged or broken, replace the cartridge.
Otherwise leave the probe in air until there is no
sign of water present in the tubing.
• Re-calibrate if necessary.
Note: A need for an unusual degree of calibration
correction could mean that the pressure sensor has
been damaged by the bulk water.
2.4 CHANGING THE
MEMBRANE CARTRIDGE
Occasion may arise where the membrane tubing
becomes damaged resulting in erroneous readings.
This is typically displayed as a sharp increase in TGP
when the probe is in water with values that remain
high over time.
To x this issue, the membrane cartridge must
be replaced, or returned to Point Four Systems
for reconditioning. It is crucial that the probe not
remain in water as this can damage the sensor and
electronics within.
Use the following steps to change the membrane
cartridge:

POINT FOUR TRACKER User’s Manual
Step 3:
Take the new membrane cartridge, and reassemble
the TGP probe in the reverse order of disassembly.
NOTE: IF POSSIBLE, APPLY SILICONE GREASE ON
THE MEMBRANE CARTRIDGE THREADS TO AVOID
THE PLASTIC BODY FROM SEIZING IN FUTURE
DISASSEMBLY.
WHEN ASSEMBLED, CHECK DOWN THE INSIDE
OF THE MEMBRANE CARTRIDGE TO ENSURE
THAT THE TUBING IS NOT KINKED.
2.5 THE TGP SYRINGE TEST
The TGP Syringe Test is a simple and effective test
to determine:
If the Silastic tubing within the TGP cartridge is
damaged and needs to be replaced.
It can also be used to routinely check the functionality
of the TGP probe.
2.6 TESTING THE CARTRIDGE
Step 1:
Unscrew the cartridge from the TGP probe.
Step 2:
Disconnect the Silastic tubing from the probe sensor
by pinching the end of the tubing and gently sliding
it off.
Step 3:
Draw the plunger of the syringe half way back and
then attach the cartridge tubing to the end of the
syringe. Note: Do not slide the tubing more then
cartridge opening.
Step 4:
Attach the cartridge tubing to the end of the syringe.
Note: Do not slide the tubing more then cartridge
opening.
5. Place the cartridge in a container of water and
GENTLY apply pressure to the plunger.
If resistance is felt in the syringe when pressed and
no bubbles appear from the cartridge when placed
underwater, there are no holes in the Silastic tubing.
This indicates that the unit is good.
If bubbles appear from the cartridge when placed
underwater, there are holes in the Silastic tubing.
This indicates that the unit needs to be replaced.
Contact supplier for a replacement TGP Cartridge.

To conrm that charging is complete, attach the
probe (right 6-pin connector). With the charger
plugged in, press the “RIGHT ARROW” button twice.
The following screen will be displayed:
The screen will display the message “Charging”
until the battery is fully charged, at which point the
message will change to “Charge Done”. Total charge
time is approximately 2 hours (for a full charge).
To avoid discharging the battery, it is advisable to
keep the Tracker connected to the charger when it
is not in use, as Ni-MH batteries have a fairly high
discharge rate while in storage and will be fully
discharged in about 3 months if the Tracker is not
used.
The Tracker can be connected to the AC charger
at any time regardless of the amount of battery life
remaining, this will not compromise the performance
of the battery, as the Ni-MH battery within the Tracker
does not suffer from the memory effect.
NOTE: IF POSSIBLE, APPLY SILICONE GREASE ON
THE MEMBRANE CARTRIDGE THREADS TO AVOID
THE PLASTIC BODY FROM SEIZING IN FUTURE
DISASSEMBLY.
WHEN ASSEMBLED, CHECK DOWN THE INSIDE
OF THE MEMBRANE CARTRIDGE TO ENSURE
THAT THE TUBING IS NOT KINKED.
2.7 TESTING THE TGP PROBE
1. Remove TGP Cartridge from the TGP probe. Make
sure TGP Probe is still connected to the monitoring
device.
2. Draw the plunger of the syringe half way back.
3. Attach syringe to sensor port in the TGP probe
using the silicon tube that was supplied with the
syringe.
4. Apply pressure (push the plunger) or vacuum
(pull the plunger) with the syringe, and check the
displayed values. The reading should respond
accordingly. (I.E. When Applying pressure, the
TGP readings will increase and when applying a
vacuum, the TGP readings will decrease).
When test has been concluded, remove syringe, re-
install cartridge, and recommission probe.
2.8 BATTERIES
The PT4 Tracker is powered by a rechargeable Ni-MH
battery, that supplies unit power for up to 70 hours
per charge.
To recharge the battery, attach the charger cable
(LEFT SIDE 4-PIN CONNECTOR) to the meter, and
insure that the correct wall plug connector is placed
on the charger (refer to section “Components”). The
meter will remain on while it is charging ( ashing the
message “No Probes Detected”).

*Note:
• Although the meter has been charged prior to
shipping, it is recommended that you fully charge
your meter prior to its rst use.
• Battery life of the Tracker is reduced depending on
the use of the backlight as well as when it is used in
extremely high or low temperatures (-5°C / +30°C).
• Store the Tracker in a cool, dry and well ventilated
place out of direct sunlight. The ambient temperature
should be kept below 30°C for long-term storage.
• Prevent charging or using batteries in extremely
high or low temperatures (-5°C / +30°C).
• The Data Logging capacity of the Tracker
signicantly exceeds the battery life of the installed
battery (normally 70 hour battery life). For logging
periods over 100 hours connect the Tracker to the
supplied power supply or a supplementary battery
pack.
• A low battery will be indicated either by the Vbat
reading 4.0V or less (in the MENU display), or by the
main display showing the message “LoBat”.
