specifications for supported ranges.
Read this manual carefully before using
the instrument!
Please follow the instructions and procedures described in
this manual. They are aimed at allowing you to make the
best of your multi-scanner and avoid any personal injuries
Disposal – WEEE Directive
The multi-scanner contains Electrical and Electronic
circuits and must be properly recycled or disposed of (in
accordance with the WEEE Directive 2012/19/EU).
Warning
The multi-scanner has been designed to calibrate and
measure low voltage signals. To ensure the safety of the
operator and the instrument, DO NOT connect the multi-
scanner to input voltages above 30 Volts.
To avoid possible electric shock or personal injury:
• The multi-scanner must not be used for any purposes
other than those described in this manual, as it might
cause a hazard.
• The multi-scanner has been designed for indoor use
only and is not to be used in wet locations.
•Do not operate the multi-scanner in environments of
explosive gas, vapour, or dust.
• The multi-scanner is not designed for operation in
altitudes above 2000 meters.
• Only use the specified mains adaptor approved for the
voltage and plug configuration in your area.
•Do not apply more than the rated voltage. See
125614 04 2017-08-11 7
• Select the proper function and range for your

measurement.
•Always position the multi-scanner to enable easy and
quick disconnection of the power source (mains
adaptor).
•Do not use the multi-scanner if it operates abnormally.
Protection may be impaired. When in doubt, get the
multi-scanner serviced.
• Disconnect test leads before changing to another
measure or source function.
• During set-up, make sure that there is correlation
between the software set-up, and the actual distribution
of the sensors connected to the multi-scanner. The
software cannot detect misplacements of sensors.
• When servicing the multi-scanner, only use specified
replacement parts. There are no user serviceable parts
inside the multi-scanner.
Caution…
8 2017-08-11 125614 04
To avoid possible damage to the multi-scanner or to
the equipment under test:
• Disconnect the power and discharge all high-voltage
capacitors before testing resistance or continuity.
• Use the proper connectors, function and range for your
measurement.
• When using the switch test function, make sure that no
other equipment, such as heavy loads or sources, is
connected in the test loop.
Note…
The product liability only applies if the instrument is
subject to a manufacturing defect. This liability becomes
void if the user fails to follow the maintenance instructions

3.1.1 A Model version
The A version operates by connecting selected channels to a single
output channel. In order to collect measurements a measuring device
is connected to the output channel.
Apart from being controlled from a connected computer, the A version
can also be operated manually.
Depending on the type of measuring device connected to the
instrument, there is a certain settling time between channel shifts.

4.0 Setting up the multi-scanner
Warning
• The multi-scanner must not be used for any purposes
other than those described in this manual, as it might
cause a hazard.
•Do not connect the multi-scanner to input voltages
above 30 Volts.
• Only use the specified mains adaptor approved for the
voltage and plug configuration in your area.
•Do not operate the multi-scanner in environments of
explosive gas, vapour, or dust.
• The multi-scanner has been designed for indoor use
only and is not to be used in wet locations.
• The multi-scanner is not designed for operation in
altitudes above 2000 meters.
•Do not apply more than the rated voltage/current. See
specifications for supported ranges.
• Select the proper function and range for your
measurement.
Caution…
In case of resistive measurements, it is very important that
125614 04 2017-08-11 15
no capacities are present in the circuit loop. If present, they
must be discharged, before wires are connected to the
instrument.
When commencing the switch test, which is in fact a
resistive measurement, the thermostats must not be
connected to any other voltage source.

ts or even possible damage to the sensors.
Connect RS232 cables and analog signal cables before the
DC power is applied.
Place the multi-scanner on an even stable surface where you intend
to use it. Make sure that the scanner is not subjected to temperature
Caution…
The multi-scanner can be set up to supply transmitters with
24V max. 27mA.
When changing the set-up from one type of sensor to
another, especially when changing from transmitters to
other types of sensors, make sure that the multi-scanner is
reset.
The order in which the sensors are connected to the multiscanner makes no difference. When setting up the
instrument, via the control software, it is possible to choose
individually which channels to use. But what matters is
that there is consistency between where to connect the
sensor to the instrument and what to write in the controlling
software. Inconsistency would result in faulty
LED channel 1 flashes once every second when the multi-scanner is
ready.
A constantly lit LED indicates which channel is currently being read.
Notice that the shifting of the internal relays can be heard when
setting up the multi-scanner and between channel shifts. This is not
an error.

Warning
Disconnect test leads before changing to another measure
or source function.
Caution…
For correct connection of sensors to the multi-scanner use the
diagrams below.
To avoid possible damage to the multi-scanner or to
the equipment under test:
• Disconnect the power and discharge all high-voltage
capacitors before testing resistance or continuity.
• Use the proper connectors, function and range for your

See section 10.0; Technical specifications for supported types of
RTDs. The calibrator accepts 2-, 3-, and 4-wire inputs, with the 4-wire
input being the most accurate.
4.2.2 Connecting Thermocouples and Voltages Sources
See section 10.0; Technical specifications for supported types of
thermocouples. The multi-scanner has a cold junction compensation
function. Normally this function should be ON and the actual
temperature of the thermocouple can be measured.
With CJC OFF, the multi-scanner will measure the difference
between the thermocouple at the junction and at its TC input terminal.
