OPERATING INSTRUCTIONS
Impulse reflectometer with memory card

General
The is a impulse reflectometer, processor controlled, with LCD display for check
and locate faults in telecommunication and power cables. For a more accurate analysis the
return loss of coaxial cables is measured additional. Additional this instrument can store
measuring values on a multimedia card. It is handy and easy to operate.
- already 20 cable types are pre-programmed, additional types can be added in the menu
- length measurement at the leading edge of the reflected pulse
- return loss measurement on the reflected pulse
- pulse amplification adjustable at cable bruise, bad connectors and other components with
too less return loss.
1 incl. high-quality NiMH accumulator
1 plugin charging device AC/AC
1 operating instructions
optional available: Imitation leather bag KLT
Measuring cable with adapter MKA 150 HQ
Plastic case
Do not measure at live objects >65V AC !
Do not expose incident solar radiation, heath and extreme coldness!
The working temperature range is 0 °C until +40 °C
avoid shocks by bumps or falling down. We recommend the use of the imitation leather
bag.
The F-measuring socket is a high-quality component. This one is designed for a
maximum diameter of 1.1 mm of the inner conductor. We recommend for a good care
of the socket to use a measuring cable with F-connector plus an according adapter.

Switch on the with key 1 , push after that key 2. Select the cable type with the
keys 1 und 2 , after that push key 3 –propagation factor and cable attenuation of the cable
types are preset at the measurements.
Push shortly key 3 .
At 0 m the positive transmitting pulse can be seen. If the connected cable is open on its
end, an additional positive going pulse appears on the display. In the case of a shorted end
of the cable a negative going pulse appears reflected from the cable end (pulse echo).
Adjust the cursor to the beginning of the pulse and read the cable length. If the cable is
terminated with a resistance equal to the impedance of the cable, no reflexion occurs when
the cable is faultless. In the case of breaks, contact faults in sleeves, short circuits or
taps/splitter in the sector to be tested, the distance to the cable beginning can be
determined by the pulse echo.
If wide pulses are used for the measurement, the echoes are stronger, but faultless
taps/splitter cause then strong echoes.

Measuring of the return loss (reflexion attenuation dBRL) :
Measurement of the cable attenuation/100m at 50 MHz:
Digital filter:
Pulse amplifier
Moving of the zero line:
Start mode:
Set cursor to pulse peak and read return loss on the left bottom corner.
The cable attenuation/100m at 50 MHz is displayed on the right bottom corner and has to be
set on a value according the data sheet of the cable. (selection possible by pushing long key 3).
If the cable attenuation is correctly set, the displays the real return loss (local
return loss). The pulse attenuation of the cable is taken into consideration by the ,
the pulse gain is set automatically.
For measurement of the return loss a pulse width of 20 ns (middle pulse) is best suitable.
Connect app. 100 - 200m cable on the , shorted or open end (all pulse energy
will bereflected). Select pulse width 20 ns. Set cursor on the pulse echo. Set the value of
the cable attenuation so that the return loss will be 0 dBRL. Read the attenuation value.
To reject or decrease interference voltage on the cable, which affect the displayed
waveform, a digital mean filter “Fi”can be connected. The display of the waveform will be
delayed to 3 seconds.
Between the storage places 0 and 9 for different cable attenuations on the storage place “V”
the gain of the pulse amplifier can be firmly set from 0 to 28 dB in steps of 4 dB to increase the
sensitivity of the at short cable length (10 –100 m).
If at the measurement of the return loss the gain is firmly set, the displayed value contains the
cable attenuation, i.e. the displayed dBRL value consist of the sum of the local return loss and
the cable attenuation.
The amplitude on the cursor position can be set to the zero line by pushing the keys 1 and 2
simultaneously. Because the has its highest sensitivity in the area of the zero line,
e.g. the graphical representation of the amplitude on the pulse peak can be seen.
This function can be cancelled by pushing the key 3.
If at a certain resolution the keys 1 und 3 are pushed simultaneously, this resolution will be
active at the switch on of the .

Measuring of the propagation factor (nvp-value) of the cable:
Measurement principle:
Propagation factor:
Zero adjustment of the transmitting pulse:
Change of the cable characteristic values:
Connect a cable with known length (e.g. 100 m) on the IRM 5. Set the cursor on the cable length
and change the propagation factor so that the pulse echo appears behind the cursor.
The measuring pulse fed into the cable will reflected by inhomogeneity of the cable i
mpedance (cable faults) and showed on the display.
The distance and the kind of the fault can be determined out of the shape and the time setting
of the reflection. (Practical experience can be obtained by test measurements).
The Propagation factor (v/c or pulse velocity) declares the velocity of electrical signals in the
cable in relation to the speed of light.
The propagation factor of the cable under test must always preset before the length
measurement.
If the propagation factor is unknown, a approximate value is set and the fault is determined from
both ends of the cable
- Select a storage place of the propagation factor
- push key 1 and 2 simultaneously up to ““appears on the display.
- Shift the transmitting pulse with key 1 or 2 so that the cursor is located at beginning
of the pulse.
- Store this setting by pushing the keys 1 und 3 simultaneously.
- Back to the normal operation with key 3.
1. In switched off condition push the keys 1 and 2 simultaneously so long, until
the display of the storage places appears.
2. Select by shortly pushing of the key 3 the parameter to be changed (inverse
display) and change with the keys 1 and 2.
3. Not used storage places can be faded in or out with the parameter ”ON“resp. ”OFF”.
Faded out storage places don't appear any more at the switch on.
The changeable parameters are:

Storage of data on the MMC card:
1. Switch on the instrument with the key 1 and after that with key 3 or over the cable
selection with the key 1 and after that with key 2.
2. For storage must be inserted a MMC card in the IRM 5 MMC.
Push the keys 1 and 3 so long, until e.g. the following appears on the display:
The displayed values are adopted from the previous settings and can now be changed.
4. Select the parameters to be changed by shortly pushing of the key 3 (inverse display)
and change with the keys 1 and 2.
- Is “BACK“marked, you come by long pushing of the key 3 in the previous menu point
5. If “START" is marked, the storage process will be triggered by long pushing of the key 3.
In this case the IRM 5 MMC picks up measuring data and stored these on the multi
media card. On the display appears the following notice:
6. If “SCAN ERFOLGREICH !“in the last line of the displays appears, the measurement
is successfully completed. The measurement point name is automatically consecutively
numbered.
7. By shortly pushing of the key 3 the IRM 5 MMC will be reset in the normal operation
mode.
