3. Measurement principle
The IRM 70 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 additionally. It is handy and easy to operate. The
special features are:
!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 witht oo less return loss.

1 plugin charging device AC/DC
1 F measuring cable with adapter MKA 150HQ
Plastic case
operating instructions
optional available:
Symmetrical measuring cable with adapter SMK-IRM
Car charging cable KFZ-LK
Imitation leader bag
Connect the plugin charging device (containing in the
delivery volume) to the charging socket of the IRM 70
(ø5.5/2.1 mm, plus pole inside). The power supply voltage
(11...24 V) and charging control is shown on the display.
After about 1 minute the backlight switches off. When
battery is fully charged, it switches on again. An
informational message appears in the display that the
charging process has finished.
Fed into a cable measuring pulses are reflected by the inhomogenities of the cable
impedance (cable fault) and made visible on the display. From the form and the time
displacement of the reflection, the nature of the fault and the fault distance can be
determined. It is also advisable to acquire practical experience by sample
measurements.

6. Operational elements
• Measurement only on strain-free objects!
• 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.
7.1.1 Switch on with cable selection
Push once more button START. Now select with buttons DOWN and UP to the desired
cable type.
7.1.2 Switch on without cable selection
Propagation factor and cable loss must be yet adjusted manually to measure.

During switching on the state of charge of the battery in the display will briefly appear
(battery is full: ca. 7 V, low battery: ca. 5.6 V, charging: if <6.2 V!)
To increase the sensitivity of the IRM 70 SD, the gain can be adjusted in 4-dB steps
from 0 to 36 dB. The gain »V« is starting from the length display to select by shortly
pressing the button ESC. With the buttons LEFT and RIGHT the gain can be stepwise
changed. Set it back by a short push on button ESC.

7.2.2 Parameter of length measurement adjust
Resolution | Firstly can be adjusted in the menu the resolution of the trace in steps. By
long pressing of the button START - until the icons appear inverted - you get to the first
parameter of the measurement. Here can be set with the buttons LEFT or RIGHT the
required value.
Pulse width| After repeated long pressing of button START (until icon inverted), the
pulse width can be changed. Rule of thumb: short cable - short pulse
Filter | Next lets switch a filter »Fi«. This can make at a restless trace by interference
from external voltages a better visibility. The disadvantage of pulse reflectometer is
generally: The presentation of the measured curve is delayed. In our case, at about three
seconds.
Storage space for propagation factors | The next setting option is to select a stored
propagation factor. If the propagation factor is not already selected when switched on or
it will need a change in use, this can be done here.
Propagation factor| As the last the propagation factor can be adjusted manually by
repeatedly long press of the button START. The propagation factor must always be set
accordingly before measuring the cable.
If the necessary settings have been made, by briefly pressing button ESC the parameter
settings are stepwise leaving again.
7.2.3 Vertical resolution / fullscreen
By briefly pressing the button UP or DOWN the display is toggled between fullscreen
and the view with measurement parameters. The set gain value is retained.

8.4 Change of the cable characteristic values
1 | To get to the settings menu for the cable parameters, press the START button when
the IRM 70 is powered off. The battery view is shown in the display. Press and hold the
DOWN button for at least 5 seconds until the SETTINGS appears.
2 | By shortly pressing of the button ESC parameter to be changed are to be selected
(inverted display) and to change by the buttons DOWN and UP. Unused memory
locations can be displayed and disappear here with the parameter »ON« or »OFF«.
Disappeared storage locations do not appear when switching on.
The adjustable parameters are:
0.80 – diameter inner conductor
3.50 – diameter screening
CPE – dielectric
ON/OFF – memory location displayed/disappeared
P: 1 – memory location (e. g. 1)
v/c=0.83 – propagation factor – 0.83 here
5.7 dB – cable attenuation at 100 m at 50 MHz
DO NOT FORGET to save the settings before exit by press and hold the START button
until the save symbol appears.
If necessary the cable parameters can be changed in the memory locations or also add
new ones. It is essential to ensure to work very carefully, because these values are
critical for each measurement. It may happen, for example, that the propagation factor
must be determined first.
