Page 14: Changing The Meter Parameters
3.2 Changing the Meter Parameters The proper combinations of jumper plugs S1, S2, S3, S4, and S5 inside the meter allow you to change various parameters of the meter. These parameters include resolution, range, units, RTD sensor configuration and sensor break configuration. You can change the parameters by moving the plugs on one or several of the jumper locations. - Page 15 The following tables summarizes what parameters you can change. Option F/C Resolution *-MF1 ¡F *-MF2 ¡F *-MC1 ¡C *-MC2 ¡C * Refer to Table 1-1, for complete models (preface section).

Page 21: 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 22: 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 24 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.
