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

!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.

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

7.2.1 Pulse amplifier

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.

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

To change the language of the device, press and hold the UP button in the battery and

charging view (for at least 2 sec). The selected language will appear in the upper area of the

display.

button held down, the color changes continuous.

The selection is saved when switching off the IRM 70 with the ESC button.

The manual saving of the settings is necessary when:

SETTINGS – set or change the cable parameters of the single presets

CABLE-SELECTION – preset (cable type) used at power on of the IRM 70

WITHOUT CABLE-TYPE – manual defined cable parameters (resolution, impulse, filter etc.)

are loaded every time the device switched on

For manual saving press and hold the START button until the save symbol is shown in the

upper right of the display.

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.
