Page 20: 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. Note The analog output is a non-isolated signal. -
Page 21: Display Hold Connections
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 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 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.
