PREFACE
Manual Objectives: This manual shows you how to set up and use the Panel Thermometer.
This meter is an economical Thermocouple Miniature 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. However, due to the internal
design of the meter, the input type and resolution CANNOT be changed on any J, K, T, or E unit.
The meter is available in many different styles. All of the Thermocouple 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-GRÓ.
Also, these thermocouple 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 numbers listed on the back cover to contact 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:

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.

SECTION 3 GETTING STARTED
3.1 Main Board Power Jumpers
Caution: The meter has no power-on switch, so it will be in operation as soon you apply power.
The meter can be configured to operate on 115VAC or 230VAC by the proper combination of the soldered wire jumpers that are located on the printed circuit board. The meter is set at the factory to be powered by the voltage specified at the time of ordering. The same transformer is used for either configuration, so all you need to do is to select the jumpers as described in this section.
Important: These changes must be performed by a qualified technician.
To change the Factory preset jumpers, do the following steps:
Disconnect the power from the unit before proceeding.
1. Remove the main board from the case. Refer to Disassembly/Assembly Section 3.8.
2. Locate the solder jumpers W1, W2, and W3 (located near the edge of the main board alongside the transformer).
3. If your power requirement is 115 V ac, solder jumpers W1 and W3 should be wired, but jumper W2 should not. If your power requirement is 230 V ac, solder jumper W2 should be wired, but jumpers W1 and W3 should not.
