Page 19: Analog Output Connections
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 Note recommended that an ungrounded thermocouple probe... -
Page 20: Display Hold Connections
3.6 Display Hold Connections The ÒDisplay HoldÓ 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 22 DC WIRING The meter can be configured at the factory to operate on a 9Ð26 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.

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. -
Page 26: Calibration Procedure
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). Doing this will compensate for the cold junction errors. - Page 27 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 28 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.
