1. Features
1.1 Introduction
The LoopTester is a versatile device that measures the signal strength emitted by
a loop and offers support in detection of a damaged coax cable and establishing
the location of a wire break in a loop.
1.2 Buttons
The LoopTester features two buttons for controlling the device.
1. Power/Menu button
2. Set/Select button
1.3 Power
To switch the LoopTester on or off, please follow the following instructions:
- Switch on: Press the “Power” button ( ) for more than 1 second.
- Switch off: Press the “Power” button ( ) for more than 2 seconds.
The illumination of the display is switched off automatically 1 minute after the
last time a switch has been pressed. In order to re-illuminate the display, shortly
press the “Set” button ( ).
The LoopTester is completely switched off automatically 10 minutes after the
last time a switch has been pressed.
When the LoopTester is switched on a splash screen is shown (gure 1). This
splash screen shows the state of the battery. Battery life depends on the type
and make of the used battery, but ball-park gures for a regular 9V alkaline
battery are:
Storage: >5 years•
Operational with display de-illuminated: ~1 month•
Operational with display illuminated: ~1 day•
When the battery has run out of power it needs to be replaced with a fresh
9V battery (Figure 2). The battery compartment is located at the rear of the
LoopTester and it can be reached by removing the rubber protective cover of
the LoopTester.

1.4 Menu
1.4.1 Activating the menu
If the LoopTester is switched on, the menu is activated by pressing the “Menu”
button ( ). Any current activity that the LoopTester might be performing at
that moment will be terminated.
1.4.2 Cycling through the menu
If the menu is visible, pressing the “Menu” button ( ) cycles through the
menu. Every time the “Menu” button ( ) is pressed, the next menu item will
be highlighted (Figure 3 & Figure 4).
1.4.3 Selecting an operation from the menu
As long as the menu is visible, a menu item will be highlighted. When the “Select”
button ( ) is pressed, the operation associated with the highlighted menu item
will be started (Figure 3 and Figure 4).

Fig. 3: Select Transmitter Fig. 4: Select Receiver
1.5 Loop Transmitter
When the Loop Transmitter function is chosen, the LoopTester emits a 6.8MHz
signal to the BNC connector. The display continuously reports the state of the
connection to the loop. Three states can be detected by the LoopTester:
Coax Ok: Connection box properly detected.1.
Coax Open: No circuit detected; coax cable not attached, coax2.
cable damaged or connection box damaged.
Coax Short: Short circuit detected; coax cable or connection3.
box damaged.
As long as a loop with a connection box is properly connected to the BNC
connector the display shows the message “Coax Ok” (Figure 5). Additionally
the display shows the type of loop that is detected (“TranX” or “TranX/ChipX”).
When no coax cable is connected to the BNC connector or when the coax loop
to the connection box is not closed, the message “Coax Open” is shown on the
display (Figure 6). When a coax cable is connected, but suffering from internal
damage in the form of a short circuit, the message “Coax Short” is shown on
the display (Figure 7).

1.6 Loop Receiver
When the Loop Receiver function is chosen, the LoopTester is tuned to receive
a 6.8MHz signal. The display reports the strength of the received signal (Figure
8). The received signal strength is reported in three ways:
Current absolute strength1.
Historic absolute strength2.
Current relative strength3.
The current absolute strength is shown in the top right corner of the display.
The historic absolute strength is shown in a running histogram that reports the
strength of the received signal in the most recent 10 seconds. The current relative
strength is shown in the bottom left corner of the display.

2. Operation
2.1 Introduction
A typical way of testing a loop requires 2 LoopTester devices and consists of the
following steps:
Connect LoopTester 1 to a loop.1.
Set LoopTester 1 to Transmit mode.2.
Check whether LoopTester 1 is properly connected to the3.
connection box.
Set LoopTester 2 to Receive mode.4.
Check the received signal strength in order to detect the5.
location of a possible loop wire break.
These steps lead to the setup depicted in Figure 9.
Fig. 9: Typical Test Set-up
2.2 Typical Signal Levels
Typical signal levels for a correctly functioning loop are approximately:
Near the coax cable: -55 dBm•
Near the connection box: -40 dBm (close to the loop wire)•
Near the End box: -50 dBm (close to the loop wire)•
Anywhere near the loop: -55 dBm(5cm distance from the wire)•
2.3 Testing the connection box
If the LoopTester is properly connected to the connection box and the LoopTester
is set to transmit mode, the message “Coax Ok” is shown on the display (Figure
10). If this message cannot be seen, but the message “Coax Open” or “Coax
Short” is displayed, the LoopTester is not properly connected to the connection
box of the loop or the coax cable might be damaged.

Fig. 10: LoopTester Properly connected
2.3 Checking for a loop wire break
If the LoopTester is properly connected to the connection box and the loop is
free of any wire breaks, the LoopTester will receive a high signal level when the
LoopTester is held near any part of the loop (Figure 11).
Fig. 11:
High Signal Level

10
If the loop suffers from a wire break, the received signal level will vary signicantly,
depending at which part of the loop the signal level is measured.
In order to accurately nd the location of a wire break, the following plan must
be followed:
Hold the LoopTester in receive mode near the loop as close as1.
possible to the connection box.
Press and hold the “Set” button (2. ) for 1 second. The reference
level will be set to the current received signal level. This is
indicated by the relative strength level in the bottom left corner
of the display being reset to 0dBm (Figure 12).
Fig. 12: Relative Signal Level Test
Move the LoopTester over the loop wire in steps of 0.5m and3.
monitor the relative level in the bottom left corner of the display.
The relative level should be in the range between -5dBm and
+5dBm on every location. If any location shows a drop of more
than 5dBm, the loop wire is probably broken.
If the loop wire is broken, the location of a break can be4.
established by searching for the lowest received signal strength.
The signal directly above a break is typically more than 20dBm
lower than the reference level (Figure 13).
