The RDA Paperless Multi-Channel Touch Screen Paperless Thermocouple or RTD Recorder Series is a value priced large format touch screen data logger that integrates measurement, display, alarm, and data logging into one slim instrument. The RDA Series is available in both 5'' and 7'' display models. The instrument is easy to install and requires no external HMI. Depending on the model, the RDA Series can support 2, 4 or up to 6 input channels with either thermocouple or RTD input type with 0.2% FS measuring accuracy. Each channel can have independent input specification, with square-root, multiplication, addition and subtraction. All channels are equipped with digital adjustment and filtering functions. The RDA Series provides a real time trend records via trend graph or bar graph. History and alarm records can be reviewed in the logger itself with 150 MB of internal storage or exported to external USB storage device. The RDA-740 and RDA-760 models have a slim installation depth of 40 mm of for use where installation space is limited.

Hello, I would like to know what happens when the memory of the chart recorder reaches the maximum (150 MB): does it stop recording or do it overwrite on historical data? If it overwrites, does it do it starting from the oldest data? Thanks

Asked by: Lale
Hi Lale Thank you for the inquiry. When memory is full the newest data will over write the oldest data. Best regards OMEGA

Does cold junction compensation require an external thermal resistor?

Asked by: jimbo1831
Hi Jimbo1831, Thankyou for the inquiry. The cold junction compensation sensor is built in the RDA unit. Best regards OMEGA

Why does advanced function not allow me to enter 128 to create equation output? I can put in any number up to 128, but not the value required.

How long does the internal memory last if recording 24hr a day?

Asked by: Steve HW
Hi Steve, The number of channels and the logging interval will impact the active logging period available. For 2 channels at 10 second interval you would have several months capacity. Best regards OMEGA

Is there a way to take a screenshot of the temperature plots?

Asked by: rlied
Hi Rlied Thank you for the inquiry. There is no screen capture function or video output feature unfortunately. Best regards OMEGA

My logger does not "store" any data. The History and the DataList tabs only start taking data once I go into that screen. If I exit back out to the Panel screen, any previous data is lost.

Does the unit come with a power supply?

Asked by: LMCO
Thank you for your inquiry. This unit does not come a power supply. This unit requires 100 to 240 Volts AC Signal to be hard wired to it.

Can I use the "Sc" button to apply an offset to the thermocouples connected to the chart recorder? If so, does the "Sc" value correspond to the offset I want to apply? I have a RDA-760-TC

Asked by: Lale
Hi Darvida, Thank you for the inquiry. Sc is a display offset to correct for probe errors. But value for each count is 0.1 on the display count. Best regards OMEGA
