3.2.2  Setting SW6 Switch 2 
Off for RTD actuation 
For thermocouple and mV inputs, the setting of SW6 switch 2 affects the displayed input in case of 
burnout or other input failure. 
Burnout is always upscale on an instrument with no display. When an input fails, the pen is driven upscale. 
However, if the SW6-2 setting is ON, the pen may be driven downscale momentarily until the input circuit 
is driven underrange. 
It is important, however, to set the switch to OFF in the case of RTD actuation. 
 
ATTENTION 
If SW6 switch 2 is ON for an RTD input, the recorder will not be able to process the input 
accurately, even when the input sensor is providing a valid signal.
