1. Introduction
AV CONDITIONER 1000 (AVC 1000) is a universal conditioner designed to interface with sensors made
in the ICP/IEPE standard.
Thanks to its small size and weight, robust design, very good operational parameters and ease of use, it
is ideally suited for carrying out measurements both in the laboratory and in the field.
The conditioner is equipped with input circuits enabling powering up the ICP/IEPE sensor, while
maintaining wide frequency response, very good linearity and low noise. Is also equipped with an LED
indicating open or short circuit in the sensor loop.
The device can be powered up either by an adapter or an internal battery pack 4xAAA.

4. Power supply
The AVC 1000 conditioner can be powered by AC adapter supplying 9V DC / 100 mA or internal AAA
batteries. When the external power supply is used, the internal battery is automatically disconnected to
prevent the discharge.

4.1. Installing / replacing batteries
In order to install or replace the batteries, remove the front panel of the casing after removing two
screws marked with the number 1 on Fig. 4.1, so that container for four AAA cells can be reached (Fig.
4.2). After putting new AAA cells into the container, insert it into the housing, and mount the front panel
back on its place with the screws.
The need to replace the cells is indicated by the ‘Low Batt’ LED.
WARNING!
Do not leave discharged batteries in the device, as it may cause a leak, resulting in damaging of
the conditioner.
WARNING!
If the conditioner is not used for a long time, remove the batteries to avoid leakage and damage.
4.2. Power supply
The unit can be powered with external power supply with 9V DC output voltage and minimal current
load of 100 mA. AC adapter is available as an option. It is recommended to use the AC transformer with
linear stabilization. Using a power supply with pulse stabilization can drastically increase the noise level
at the output of the conditioner.
WARNING!
Pay attention to the polarity of the adapter plug –it should be in line with the outlet polarity
marked on the top of the cabinet. Connecting the power supply incorrectly may damage the
conditioner.

5. Using the conditioner
Operation is reduced to few steps:
»Connect an ICP/IEPE standard sensor with the IN connector using a shielded cable, terminated
with BNC plug
»Connect the conditioner output to measuring equipment (oscilloscope, data acquisition card,
etc.)
»Connect an external power supply - necessary if the batteries haven’t been installed in the device
»Turn on the conditioner - switch should be placed to the ON position
When the conditioner is turned on, the red LED labeled Power will lit, which means that the device is
ready for use.
6. Troubleshooting
The table contains the solution to some problems that the user may encounter during the operation of
the conditioner.
Problem
Solution
The unit will not turn on
Check if the switch is set to the ON position.
If the conditioner is battery powered, make sure that the batteries are installed in
the device and that they are in working order.
If an external power supply is used, make sure that the power adapter is connected
correctly (with compatible polarity), in case of a regulated power supply make sure
that it is set to supply 9V, check that the power supply is turned on.
No signal on
conditioner’s output
Check if the ‘Sensor Error’ LED shines, if yes - check connection of the sensor to the
conditioner and make sure that the sensor cable is OK - any breaks, cuts and
abrasions qualify it to be replaced. Make sure that the sensor is operational.
Output signal
conditioner is noisy
and/or disturbed
When an external power supply is used, make sure that it is a transformer with
linear stabilization. Using a power supply with pulse stabilization (inverter) may
increase the noise level.
Make sure the signal cable used to connect the sensor and the measuring
equipment are shielded cables.
Make sure that nearby there are no electrical devices turned on, that may interfere
with the operation of the conditioner.
Disconnect the AC adapter from the conditioner and power it up with batteries - in
some cases, excessive noise can penetrate from the network through the AC
adapter and affect the operation of the conditioner
If the above table does not include the problem or given solution has been unsuccessful, contact AMC
VIBRO service.

7. Recycle
7.1. Hazardous Materials
AVC 1000 system does not use any hazardous materials outlined by RoHS. These
regulations confirm that lead, mercury, cadmium, hexavalent chromium,
polybrominated biphenyls, polybrominated diphenyl ether, or other battery related
materials are limited to no more than trace amounts.
7.2. Recycling Facilities
When decommissioning out of use devices, minimize the impact of the waste created. Refer to local
waste removal administration for current information on proper material collection and recycling.
