RCJ (Cold junction compensation) (Setting range: ON/OFF)[Description]• This parameter sets whether or not to perform the RCJ(Cold junction compensation) for the thermocouple input.Use the factory default setting (ON: performs theRCJ) under normal conditions.: Performs the RCJ (Cold junction compensation).: Does not perform the RCJ (Cold junction compensation).• Set this parameter to OFF under the conditions that theRCJ is not needed, such as when the RCJ is performedoutside of the PXR or when the temperature deviationsare recorded.[Setting example] Changing the RCJ (Cold junction compensation) from ON to OFFDisplayPV indicationSV indicationPV indication1.2.3.4.5.6.Press and hold the SEL key for five seconds.will be displayed.Press the key to display .Press the SEL key once.The current setting ( ) will be displayed.Operating procedurePress the or keys to flicker and to display .Press the SEL key once. will be displayed and will be registered for . After that,the controller will operate with the RCJ (Cold junction compensation) being .(Repeat the procedure from 3 to 5 to check the set value.)If you want to display the operation status, press and hold the SEL key for two seconds.The SV will be displayed on the display area.If unoperated state continues, the PV will be displayed.59
Adjusting the PV (Measured value) display (0%) (Setting range: -50 to 50% FS)Adjusting the PV (Measured value) display (100%) (Setting range: -50 to 50% FS)[Description]• The user-definable functions are independent of the adjustmentvalues of the PXR. Setting the parameters ofand to can return to the factory default settings.5.Return the parameter ofto ON.[Operating example for input range of 0°C to 400°C]1. Prepare the following devices before adjustment by usingthese parameters.• DC voltage standard generator1 to 5V (for voltage input)0 to 100 mV (for thermocouple input)• Decade resistance box100.0 to 400.0 Ω (for resistance bulb input)2.Set the parameter of to OFF.3.Apply a voltage that is equivalent of 0%.If there is an error large enough to impair its accuracy, setthe parameter of .
