14 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 .
15 3.6 Display Hold Connections The ÒDisplay 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 of f, the display will update itself 2.
16 3.7 Main Power Connections Connect the ac main power connections as shown below . W ARNING: 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.
17 DC WIRING The meter can be configured at the factory to operate on a 9Ð 26 VDC non-isolated power . The DC voltage option is specified at the time of ordering. See T able 1-3 for model number listing. An AC powered meter cannot be converted to a DC powered meter or vice versa.
18 3.8 Disassembly/Assembly Y ou must go through the following steps in order to remove the printed circuit board from the case if you want to change from 1 15V AC to 230V AC (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.
19 Figure 3-13. Removing the PC Board from the Case When re-installing the printed circuit board: 1. Hold the case (with the two mounting holes facing upwards and to the right side of the case) in the left hand. 2. Hold the printed circuit board with the components showing (soldered side down) in the right hand.
20 SECTION 4 OPERA TION AND CALIBRA TION Important: These changes must be performed by a qualified technician. W ARNING: 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! 1.
21 4.2 CALIBRA TION PROCEDURE 1. Remove the front lens. Connect power to the meter , observing proper wiring procedures. 2. Connect the precision resistance source to the P3 connector observing proper wiring configuration. For 3Ðwire connections, use pins 1, 2, 3, and 4.
