Class E installations.
• Powerful troubleshooting tools such as high resolution TDR and TDCrosstalk
• Supports UTP, STP, ScTP and FTP cables, Permanent and Channel link testing
• Supports fiber optic cable testing in combination with compatible Optical testing
instrumentation, eg. Optical Power Meter PM420.
• 2 way Autotest function for fast and reliable testing
• Talk & Trace interface provides full duplex communication and is also intended for
locating cables
• Locators for locating cables
• Main test standards and cable types (copper and fiber) are preprogrammed
• Large memory capacity for storing measured data
• Powerful Windows software for data analysis and Test report evaluation
• Graphical representation of results on instrument's display and PC
• Simple firmware upgrading
This manual provides information for connection, operation, test procedures and
maintainance of the Multi LAN 350.
The manual is divided into five sections, each covering a particular aspect of the
operation.

2General information
2.1 Safety and operational precautions
2.1.1 Warnings
To ensure a high level of operator's safety while carrying out various measurements
and tests using the Multi LAN 350 and MultiLAN350 RU, as well as ensuring that the
test equipment remains undamaged, it is necessary to consider the following general
warnings:
The test equipment is intended for / to be used (safetyextra lowvoltage)
environment only.
Do not connect the instrument to public telephone network!
Never connect the test equipment to an active network.
Service is allowed to be carried out onlybyan authorised person!
Use onlystandard or optional test accessories supplied byyour distributor!
Use onlyconnector types equivalent to those built in the instrument to avoid
damage to the instrument components.
2.1.2 Batteries
Replacement
Note
Insert cells correctly, otherwise the instrument will not operate and the batteries could
be discharged.
If the instrument is not to be used for a long period of time remove all batteries from the
battery compartment.
Warnings!
When batterycells have to be replaced, before opening batterycover disconnect
anymeasuring accessoryconnected to the instrument and turn power off on the
instrument.
Use onlypower supply/charger delivered from manufacturer or distributor of the
test equipment to avoid possible fire or electric shock.
The real time clock setup will be lost if the batteries are removed for more than 15
minutes !
Stored measurement graphs will be lost immediatelyafter the batteries are
removed.
Precautions on charging of newbatteries or batteries unused for a longer period
Unpredictable chemical processes can occur during charging of new batteries or
batteries that were unused for a longer period of time (more than 3 months). NiMH and
NiCd batteries are affected to a various degree (sometimes called as memory effect).
Multi LAN 350 General information
8
As a result the instrument operation time can be significantly reduced at the initial
charging/discharging cycles.
Therefore it is recommended:
- To completely charge the batteries (at least 14h with in built charger).
- To completely discharge the batteries (can be performed with normal working with the
instrument).
- Repeating the charge/discharge cycle for at least two times (four cycles are
recommended).
When using external intelligent battery chargers one complete discharging /charging
cycle is performed automatically.
After performing this procedure a normal battery capacity is restored. The operation
time of the instrument now meets the data in the technical specifications.
Notes
The charger in the instrument is a pack cell charger. This means that the batteries are
connected in series during the charging so all batteries must be in similar shape
(similarly charged, same type and age).
Even one deteriorated battery (or just of an another type) can cause an improper
charging of the entire battery pack (heating of the battery pack, significantly decreased
operation time).
If no improvement is achieved after performing several charging /discharging cycles the
shape of individual batteries should be determined (by comparing battery voltages,
checking them in a cell charger etc). It is very likely that only some of the batteries are
deterirated.
The effects described above should not be mixed with normal battery capacity decrease
over time. All charging batteries lose some of their capacity when repeatedly
charged/discharged. The actual decrease of capacity versus number of charging cycles
depends on battery type and is provided in the technical specification from battery
manufacturer.
Information on batteries
Onlyrechargeable NiMH batteries (size C) can be used. The operating hours are
given for a nominal capacityof 3500 mAh.
Do not use standard batteries !
2.1.3 Power supplyconsiderations
When using the original power supply adapter / charger A1135 the instrument is fully
operational immediately after switching it on. The batteries are charged at the same
time, nominal charging time is 16 hours.
The batteries are charged whenever the power supply/charger is connected to the
instrument. Inbuilt protection circuits control the charging procedure and assure
maximal battery lifetime.

2.1.4 FactoryCalibration, Self Calibration
FactoryCalibration
It is essential, that all measuring instruments are regularly calibrated. For occasional
daily use, we recommend an annual factory calibration to be carried out. When the
instrument is used continuously every day, we recommend a factory calibration every
sixth months.
Contact the manufacturer or your local distributor for further information.
Self Calibration (with the Attenuation calibration module )
The test calibration serves to perform a fast check up of the instrument and remote unit
hardware. If using an other remote unit as delivered it is obligatory to perform it.
The calibration can be performed with the Attenuation calibration module ACM-350.
When the instrument is used continuously every day we recommend to perform self
calibration at at least once per month.
The user should run it at least one per month.
Note:
The main and remote unit should be switched on at least 1 minute before performing
the self calibration.
The self calibration should be performed at room temperature.
2.1.5 Service
For repairs under or out of warranty time please contact your distributor for further
information.
