Operation of Front Mounted 10” Recorders (RCDR318, RCDR319)
Built in 10” thermal pen recorders can be purchased with CARON chambers. The
recorders are shipped installed on the outer door of the chamber from the factory and
require no further installation. Unlike ink pen recorders, the thermal recorders draw their
own chart and control lines.
The 10” recorders have been setup at the factory in the following configuration: 7 Day /
24 Hour / Temperature 0-100°C / Humidity 0-100% (for dual input recorders). If this is
not the ideal configuration for an application, the recorder may be reconfigured using the
following process:
Configuring the recorder:
In order to configure the recorder, you will need to enter the set-up mode of the recorder.
To enter the set-up mode of the recorder, press and hold the Change Chart button (#3)
until the thermal pen arm begins to move off scale and then release the button. Similar
to the 6” recorder.
Note: The green LED light will flash fast while the thermal pen arm is moving off scale.
Wait until the thermal pen arm has moved completely off scale and stops (the green LED
light will stop flashing and will be steady On). Unscrew (counter clockwise) the chart
"hub" knob at the center of the chart and remove the recording chart paper. Gently lift
the thermal pen arm just enough to be able to slide the paper out from beneath it.
Remove the recording chart paper and place the Setup Chart onto the recorder. This
chart contains the configuration categories of the recorder (Probe Input, Inner Chart
Temperature, Outer Chart Temperature, Temperature Scale, Chart Rotation Speed,
Input Filtering, Optional Relay Contacts and Date/Time for internal clock).
Next, press and hold either button #1 or #2 until the green LED light goes out and release
the button. If this step is successfully completed, the pen arm will move to the outermost
graduation ring of the Setup Chart. Use the Left (#1) or Right (#2) arrow buttons to adjust
the center of the thermal pen to be on this outermost graduation ring.
Position the Setup Chart so that the tip of the thermal pen is in the center of the Start
circle. Tighten the chart hub knob to secure the chart in place. Next, press and release
the Change Chart button to begin. The chart will rotate to the first category (Input #1).
Use the Left and Right arrow buttons to move the thermal pen arm to the desired option
of each category. Press and release the Change Chart button to accept the selection
and advance to the next category. You must press and release the Change Chart button
when you have finished configuring the last category in order to save all of the changes
that have been made to the recorder's configuration.
