PREFACE

Manual Objectives: This manual shows you how to set up and
use the RTD Panel Thermometer.

This meter is an economical Miniature Temperature Panel
Thermometer featuring a large display with a linearized analog
output that is supplied as a standard feature.

Each of the models* can be converted by the user to display in
degrees Fahrenheit or Celsius between one degree and a tenth
degree resolution.

RTD is an abbreviation for resistive temperature detector. The
meter is designed to measure 100 ohm platinum resistance with

0.00385 temperature coefficient, also known as the European
curve. The RTD will change resistance with a change in
temperature. When using a 2-wire measurement configuration,
lead wire impedance can contribute significant error to the
temperature measurement. When using long lead wires a 3- or
4-wire measurement configuration is recommended.

The meter is available in platinum RTD with 2-, 3-, or 4-wire
connections. All of the models listed in Table 1-1 come standard
with red LEDs, and can be ordered with a green LED display as
an option. The part numbers would then end with Ò-GR".

Also, these meters can be ordered with different power
configurations. Refer to Table 1-3 for available choices.

*Refer to Table 1-1 for the complete listing of models available.

SECTION 1 INTRODUCTION

1.1 UNPACKING

Remove the Packing List and verify that all equipment has been
received. If there are any questions about the shipment, use the
phone number for the Customer Service Department nearest
you.

Upon receipt of shipment, inspect the container and equipment
for any signs of damage. Take particular note of any evidence of
rough handling in transit. Immediately report any damage to the
shipping agent.

The carrier will not honor any claims unless all shipping
material is saved for their examination. After examining
and removing contents, save packing material and
carton in the event reshipment is necessary.

Verify that you received the following items in the shipping box:

QTY DESCRIPTION

1 Panel Thermometer with 3 small connectors plugged

into the rear of the meter.

1.2 SAFETY CONSIDERATIONS

This device is marked with the international caution symbol. It is important to read this
manual before installing or commissioning this device as it contains important
information relating to Safety and EMC (Electromagnetic Compatibility).

Unpacking & Inspection

Unpack the instrument and inspect for obvious shipping damage. Do not attempt to
operate the unit if damage is found.

This instrument is a panel mount device protected in accordance with Class I of EN
61010 (115/230 AC power connections). Installation of this instrument should be done
by Qualified personnel. In order to ensure safe operation, the following instructions
should be followed.

This instrument has no power-on switch. An external switch or circuit-breaker shall be included in
the building installation as a disconnecting device. It shall be marked to indicate this function, and
it shall be in close proximity to the equipment within easy reach of the operator. The switch or
circuit-breaker shall not interrupt the Protective Conductor (Earth wire), and it shall meet the relevant
requirements of IEC 947–1 and IEC 947-3 (International Electrotechnical Commission). The switch
shall not be incorporated in the mains supply cord.

Furthermore, to provide protection against excessive energy being drawn from the mains supply in
case of a fault in the equipment, an overcurrent protection device shall be installed.

• The Protective Conductor must be connected for safety reasons. Check that the power
cable has the proper Earth wire, and it is properly connected. It is not safe to operate
this unit without the Protective Conductor Terminal connected.

• Do not exceed voltage rating on the label located on the top of the instrument housing.

• Always disconnect power before changing signal and power connections.

• Do not use this instrument on a work bench without its case for safety reasons.

• Do not operate this instrument in flammable or explosive atmospheres.

• Do not expose this instrument to rain or moisture.

• Unit mounting should allow for adequate ventilation to ensure instrument does not
exceed operating temperature rating.

• Use electrical wires with adequate size to handle mechanical strain and power
requirements. Install without exposing bare wire outside the connector to minimize
electrical shock hazards.

EMC Considerations

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.
