Glossary
Also known as a cigarette lighter adapter. This is an optional cable
with DC-to-DC sockets.
The Autoscale function automatically rescales the axes of the
currently selected graph based on the data it receives.
By default, autoscaling is always on.
A button always refers to an area on the screen that you can
click to select functionality.
A key always refers to hardware push buttons on the keyboard
that you can press.
The Control Panel is located in the bottom of the carrying case. It
has the keyboard and these labeled areas: Power, Computer, and
Measure.
The Data Panel displays in the PIT5000 application on the right
side in all tabs. The panel displays different information including
flashing red alarms and the following four buttons: Start Program,
Begin Test, End Test, and Add Notes.
A digital I/O device that provides 5 volts to the stroke counter and
converts the stroke count to a digital signal to the computer via
USB.
The contacts in a Dry contact set do not have electrical power on
them. The dry contacts are for the (non-supplied) pump stroke
counter.
Edit boxes (also known as fields) are for you to enter your data.
NPT is an abbreviation of National Pipe Thread (Tapered). This is a
standard male tapered pipe thread.
PIT is an acronym for Pipeline Integrity Tester.
P Leak Pressure refers to Preliminary Leak Test Pressure. Some
customers perform a 15-minute leak test before going to higher
pressures.
You may see different ways of expressing these concepts in
printed material, on the PIT5000, and in the software. The most
common are:
Press
P Leak and PLeak
PTest

PTest Instrument Pressure
PTest is an abbreviation of the words Pressure Test.
Instrument Pressure refers to the pressure of the PIT5000
device.
The Quick-test connection is located on the Control Panel in the
Measure pane.
RTD is an abbreviation of Resistance Temperature Detectors.
Strip Chart is a tab in the PIT5000 application that displays a live
plot of pipe pressure (Press), ambient temperature (T-Amb) and
pipe temperature (T-Pipe) versus time in order to record the
hydrostatic test and its duration.
Stroke Count versus
Stroke Counter
Stroke Count refers to number of recorded pump strokes.
Stroke Counter refers to the digital counter that records pump
strokes. It is connected to the pump using the Stroke Counter
cable.
You may see different ways of expressing these concepts in
printed material, on the PIT5000, and in the software. The most
common are:

Digital battery voltage indicator.
Note: If two batteries are
connected using both 12 V dc
connections on the Control
Panel, then this display averages
the voltage. This averaging
makes the LCD unreliable.
It reminds you of three levels:
1. The highest allowable is
15.0 V.
2. An audible alarm sounds
when the battery voltage
goes below 10.5 V.
3. The PIT5000 shuts off at
10.0 V.

Troubleshooting Guide
An alarm sounds
inside the PIT5000
case
Low battery voltage (< 10.5 V)
has occurred and the internal
power inverter’s audible alarm
sounds.
Connect charger to the battery and
recharge it.
The voltmeter on
control panel reads
approximately 10.0 V
or less.
The computer does
not turn on or there
are no pressure or
temperature
measurements being
read.
Low battery voltage
(< 10.0 V) has resulted in a
shutdown of the internal
power inverter.
No power is going to the
measurement device or
computer power cord.
Turn the computer off if
necessary.
Move the power toggle switch to
Off.
Connect the charger to the
battery and recharge it.
The PIT5000 battery
does not charge.
Check for proper charger
operation (output should be
12 V dc).
Replace charger if needed.
The voltmeter on the
control panel
reads > 10.5 V and
the computer does not
turn on or there are no
pressure or
temperature
measurements being
read.
The PIT5000 power toggle switch
may be in the Off position.
Move the PIT5000 power toggle
switch to the On position. Turn the
computer on.
Internal power inverter locked up.
Turn computer off if necessary.
Move the power toggle switch to
Off and wait 1 minute.
Connect the charger to the
battery and recharge it.
Internal power inverter fuse may
have blown.
You will have to return the device for
repair to Meriam because it indicates
something is not working properly.
One or both
temperature
measurements fail to
plot.
RTDs not properly connected.
Check the connections of the
RTD cable on the Control Panel
and at the RTD.
There is a bad cable.
Swap RTD cables to see if the
problem follows the cable (one
measurement fails).
Replace the RTD cable as
needed.

Measurements (Press,
T-Amb & T-Pipe) are
not being plotted on
the Strip Chart in
PIT5000 application
This may be a USB
communication port issue.
Check the Communication Port
setting in the Setup tab > PC Setup
sub-tab. It should display COM3.
The output measurement may
have locked up.
Turn the computer off.
Move the toggle power switch to
Off and wait 1 minute.
Move the toggle power switch to
On.
Turn the computer on.
This may be a malfunction of the
Serial to USB converter.
Replace Serial to USB converter.
The Stroke counter
does not update in the
PIT5000 application
The counter signal is not being
received by the digital counter.
Check connection of counter
cable at the Control Panel and at
the dry contacts at the pressure
pump.
Confirm the counter cable is
delivering 5 V dc to dry contacts.
The stroke counter
cable does not deliver
5 V dc to the dry
contacts you
connected at the
pump.
The PIT5000’s digital counter has
an output failure.
Check wiring to the digital
counter.
Replace the faulty wire as
necessary.
The computer and
measurement device
do not turn on.
The power source is not
connected.
The power toggle switch is in the
Off position.
Move the PIT5000 power toggle
switch to the On position.
The time that is
displayed on the Strip
Chart’s x-axis is
incorrect.
The computer’s clock needs to be
set.
Time zones are not used. Only
Universal Coordinated Time (UTC)
is used.
Set the clock on the computer.
The PIT5000 application uses the
computer clock for displaying
time.
The PIT5000
application did not
automatically start.
Start the PIT5000 application
manually.
Double click the PIT5000 icon on
desktop.
