2.0 Safety instructions

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 and/or damage to the instrument.

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 2002/96/EC).

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.

 Do not operate the multi-scanner in environments of

explosive gas, vapour, or dust.

 Do not apply more than the rated voltage. See

specifications for supported ranges.

 Select the proper function and range for your

measurement.

 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.

125614 02 02-10-2009 7

 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.

Caution…

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 described in this manual or uses unauthorized spare parts.

3.1 Multi-scanner models

The Advanced Signal Multi-scanner is available in 3 different models; 801, 802 and 803 in two different model versions – A and B.

Model ASM-801 with Multi input

Model ASM-802 with Mini-Thermocouple input

Model ASM-803 with LEMO input

125614 02 02-10-2009 11

Pos. Description

LED indicating which channel is being read. LED channel 1

will flash once a second when the Multi-scanner is ready

for operation.

Screw connection, max. wire size 2,5mm

Miniature thermocouple connector from OMEGA, type

SMP-U-F

Connector from LEMO, type ERA.1S.304.CLL

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.

in series, the analogue line out of the next instrument must be connected here. For applications, see section 4.3.

ANALOG BUS OUT. Connect the measuring device here

or if multiple multi-scanners are connected in series,

connect the instrument in front to the ANALOG BUS OUT.

SLAVE. If multiple multi-scanners are connected in series,

the RS232 master line of the succeeding instrument must be connected here. For applications, see section 4.3.

PC/Master. Connect the controlling computer here, or if

multiple multi-scanners are connected in series, connect the instrument in front to the PC/MASTER.

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.

 Do not connect the multi-scanner to input voltages

above 30 Volts.

 Do not operate the multi-scanner in environments of

explosive gas, vapour, or dust.

 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 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.

125614 02 02-10-2009 15

4.1 Preparing the multi-scanner

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 fluctuations e.g. draught or sunlight.

Caution…

The multi-scanner can be set up to supply transmitters with

LED channel 1 flashes once every second when the multi-scanner is ready.

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 measurements or even possible damage to the sensors.

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.

4.2 Connecting sensors to the multi-scanner

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

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.

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.
