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.
SECTION 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). 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.
SECTION 2. ABOUT THE METER 2.1 DESCRIPTION The Differential RTD meter is a value packed indicator/controller. Four full digits accurately display your temperature. Select from DIN (Alpha = .00385) or NIST (Alpha = .00392); 2,3, or 4 wire RTD. 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.

2.7 DISASSEMBLY You may need to open up the meter for one of the following reasons: • To check or change the 115 or 230 Vac power jumpers. • To install or remove jumpers on the main board. Disconnect the power supply before proceeding. To remove and access the main board, follow these steps: • Disconnect the main power from the meter. • Remove the back case cover. • Lift the back of the main board upwards and let it slide out of the case.
SECTION 3. GETTING STARTED Caution: The meter has no power-on switch, so it will be in operation as soon you apply power. If you power off/on the meter, or perform a hard reset (press the RESET button twice), the meter shows "RST", followed by "D.RTD". 3.1 RATING/PRODUCT LABEL This label is located on top of the meter housing (Refer to Figure 3-3). 3.2 MAIN BOARD POWER JUMPERS Important: If you want to change the Factory preset jumpers, do the following steps; otherwise go to section 3.3.
