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.
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.
SECTION 2 ABOUT THE METER 2.1 Front of the Meter Figure 2-1 shows the panel thermometer. Figure 2-1. Panel Thermometer Features: Display: 3 1/2 Digit, 7-Segment Red or Green LED Full-size 14.2 mm (0.56") LED Display Analog Output Standard 3/64 DIN Standard Panel Cutout Removable Screw-Clamp Cable Connector Display Hold Capability...
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 115 Vac or 230 Vac by the proper combination of the soldered wire jumpers that are located on the printed circuit board.

3.2 Converting °F to °C (vice versa) You must remove the printed circuit board from the case in order to change from the Fahrenheit to Celsius (or vice versa). This change must be performed by a qualified technician in order to avoid damage to the unit. Disconnect the power from the unit before proceeding.
Section 3.3 Installation and Panel Mounting Figure 3-3 shows the panel cutout dimensions, the dimensions for the panel thickness, and the mounting clamp for mounting the unit in a panel. Connections will be done after mounting the unit. Remove the lens by inserting a paper clip or a small flat blade screwdriver into the rounded corner of the lens and lift out.

Page 19
3.4 Sensor Input Connections (Continued) To connect the input to the unit, attach the thermocouple probe to the 2-pin female connector that is supplied with the unit. Refer to Figure 3-4 for wiring instructions and Table 2-1 for wire colors. Plug the female connector into the P3 male connector at the rear of the meter.
3.5 Analog Output Connections The analog output is a linearized millivolt signal that is equivalent to the displayed temperature. It comes as a standard feature with every unit. The resolution of the analog output is no greater than the resolution of the display. The analog output is a non-isolated signal, therefore, it is recommended that an ungrounded thermocouple probe be used to prevent ground loop problems.
3.6 Display Hold Connections The “Display Hold” function can be used to freeze the display. Connect a single pole, single throw (SPST) switch between pins 1 and 2 on the P2 connector. The display will stop updating when this switch is on. When this switch is off, the display will update itself 2.5 times per second.
3.7 Main Power Connections Connect the ac main power connections as shown below. WARNING: Do not connect ac power to your meter until you have completed all input and output connections. Failure to do so may result in injury! This device must only be installed electrically by specially trained electrician with corresponding qualifications.
Page 23
DC WIRING The meter can be configured at the factory to operate on a 9–26 Vdc non-isolated power. The DC voltage option is specified at the time of ordering. See Table 1-3 for model number listing. An AC powered meter cannot be converted to a DC powered meter or vice versa.
3.8 Disassembly/Assembly You must go through the following steps in order to remove the printed circuit board from the case if you want to change from 115 Vac to 230 Vac (or vice versa) or to change from Fahrenheit to Celsius (or vice versa). These changes must be performed by a qualified technician in order to avoid damage to the unit.

PULL TAB HERE PUSH HERE PC BOARD Figure 3-9. Removing the PC Board from the Case When re-installing the printed circuit board: Hold the case (with the two mounting holes facing upwards and to the right side of the case) in the left hand. Hold the printed circuit board with the components showing (soldered side down) in the right hand.
SECTION 4 OPERATION AND CALIBRATION Important: These changes must be performed by a qualified technician. WARNING: Do not connect ac power to your meter until you have completed all input and output connections. Failure to do so may result in injury! Wire the meter according to the wiring section.
Meter calibration must performed using thermocouple calibrator. If a millivolt source is used instead, be sure to connect the output of the millivolt source to an Omega MCJ Electronic Ice Point (or equivalent) of the appropriate thermocouple type (or an ice bath).
Page 28
Connect the thermocouple calibrator output signal to the thermocouple input connector P3 as shown in Figure 4-2. Connect the negative (red) thermocouple wire to connector P3, Pin 1. Connect the positive thermocouple wire to connector P3, Pin 2. Be sure to observe polarity and use the correct thermocouple wire (Type J wire for Type J meter).
Page 29
Set the thermocouple calibrator to match the thermocouple type of your meter. Adjust the thermocouple calibrator to output the temperature shown in the first line of column 2. Check to see that the unit displays the temperature shown in column 3. If not, adjust the zero potentiometer until it reads that simulated value.
