ANALOG VOLTAGE OUTPUT:
The analog voltage output can be used to interface with other instruments such as
recorder, printer, remote indicator, 4-20 mA converter, etc.
The following rule must be observe in order to avoid reading inaccuracies or possible
damage to the instrument.
1. If grounded or naked thermocouple is used, the interface device's circuit
common must not be connected to earth ground.
2. The input impedance of the interface device must be greater than 10K
3. Be sure that the AC line voltage is never connected to analog output.
WIRING DIGRAM:
1. Connect the AC line to the rear of instrument. The model 765 can be used with
115V AC or 230V AC, 50/60 Hz. Refer to DRAWING 4 and DRAWING 5.
2. Connect the two thermocouple leads to the rear of instrument and be sure to
observe the correct polarity of thermocouple leads. Refer to DRAWIN 4 and
DRAWING 5.
3. The "HOLD" function is activated by connecting the "HOLD" terminal to
ANALOG GND TERMINAL
