The recorder output connector on the back of the Controlled Rate Freezer
provides an analog signal representing process temperature(s) that can be
plotted on an optional strip chart recorder. The controller can be set to
output Chamber or Sample temperature, a scanned combination of both,
or Off. Refer to Section 3.
Note The chart recorder function is calibrated to match the non-linear
scale on the chart recorder paper (P/N 197044). ▲
The printer on the top of the Controlled Rate Freezer provides a visual
record of a profile run, including any errors which might have occurred.
Run data is captured in a printer buffer for later reprinting, even if the
printer is not enabled during the Run. The printer buffer is cleared at the
start of each new run.
It is recommended that a supply of printer paper be kept on hand. If paper
should run out during a freezing run, first install the paper. Then when the
Run is complete, the print-out may be re-started.
