Advanced Settings – for service technician only
ATTENTION: This section is for service technicians or experienced users
only. Altering the following settings can result in malfunction or inaccurate
temperature readout.
Air and Sample Temperature Display
The controller has the capability to display either the air or sample temperature
readout. For the normal operation, the sample-simulated temperature (P3) is
displayed in order to provide users the content temperature. For the actual
operation, the air temperature (P1) is used to control the compressor’s cycle.
This is a useful tool for you to make a precise adjustment, or temperature validation
process.
“Lod” setting allows you to display either air (P1) or sample (P3). Press and hold both
[SET] and [DOWN] at the same time until “Hy” appears on the display.
Press [UP] or [DOWN] until “Lod” shows up. Press [SET] to enter the setting. Press
[UP] or [DOWN] to toggle between the air temp “P1”, or the sample temp “P3”.
Press [SET] once to confirm the new setting. The display will now show the temp you
have selected.
We strongly recommend you to change the “Lod” setting back to “P3”
before you complete the service. This will allow users to see the sample-
simulated temperature, and the controller will be able to alert when the
sample temp is out of range.
Calibration / offset
“OT” setting allows you to change the air probe’s calibration. “O3” setting allows you
to change the sample probe’s calibration.
Please be sure you have a NIST traceable and calibrated thermometer. Place your
thermometer’s probe next to our sensor accordingly, air vs. air, or sample vs. sample,
before making an adjustment on either “OT” or “O3”.
For more advanced settings, please contact our Technical Service Department for
