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 receive the following items in the shipping box:
QTY DESC IPTION
1 Differential THermocouple Meter with all applicable connectors
attached.
1 wner's Manual
1 Set Mounting brackets
1 QuickStart Manual
If you ordered any of the available options (except the " L"
lank Lens option), they will be shipped in a separate container
to avoid any damage to your indicator/controller.

1.2 SAFETY CONSIDE ATIONS
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).
This instrument is a panel mount device protected in accordance with EN
61010-1:2001, electrical safety requirements for electrical equipment for
measurement, control and laboratory. 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 main
supply cord.
Furthermore, to provide protection against excessive energy being drawn
from the main supply in case of a fault in the equipment, an overcurrent
protection device shall be installed.
• 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.
Failure to follow all instructions and warnings may result in injury!

SECTION 2. ABOUT THE METE
2.1 DESC IPTION
The Differential Temperature meter with thermocouple is a value packed
indicator/ controller. Four full digits allow for an accurate display of your
temperature. Select from J, K, T or DIN J thermocouple types. Your
meter may be a basic indicator or it may include analog output or dual
relay output. Analog or dual relay output must be ordered at time of
purchase. Analog output is fully scalable and may be configured as a
proportional controller, or to follow your display. Dual 5 amp, form C
relays control critical processes. Front panel peak detection and memory
is also standard.
2.2 STANDA D FEATU ES
The following is a list of features:
* 4-digit, red, 14 segment LED Display
* NEMA 4/Type 4 Front Bezel
* ±0.5 °C accuracy
* Cross channel isolation up to ±5V
* Match Capability
* Automatic Decimal Adjustment
* Non-volatile memory-no battery backup
* 115 or 230 Vac 50/60 Hz power supply or
10-32 Vdc or 26-56 Vdc
* T1, T2, T1-T2 display
OPTIONAL FEATU ES
* Dual 5 amp, form C relay outputs
* Scalable analog output
* Analog out proportional control
* Front-panel deviation correction
* Easy setup for proportional control
