•Adjustment of Calibration of the Recorder
The recorder is accurately adjusted before leaving the plant. It will not be affected even if the
power is cut off . If adjustment is required, please perform a calibration according to the following
procedures:
1. Operate the refrigerator continuously. Use the recorder to continuously record the temperature
curve for at least 2 hours after the refrigerator has reached a steady state (fl uctuation of displayed
temperature is regular).
2. Put a standard thermoelectric couple into a solution bottle with 100ml of glycerol (10%). And
place the bottle in the box together with sensor of the recorder;
3. Compare the temperature values of standard thermoelectric couple and recorder when
the bottle is placed in the refrigerator for about 4 hours and the temperature of glycerol is the
same with that in the box. If temperature value of the recorder is different with that of standard
thermoelectric couple, press the button on the left of the panel (1#) or on the right side (2#) to
adjust the temperature value on the recorder and to make it in accordance with indicated value of
the thermoelectric couple.
Note: The recording pen starts moving after the button is released for 5 seconds.
The recorder was calibrated before leaving the plant. Please do not adjust it in non-
special situation.

• USB function is (optional for HXC-158/158B/358/358B/608/608B).
The control panel has a USB port, which allows extraction of temperature data and other test data via
a jump drive. It can automatically collect and store the test data within the recent 10 years. The latest
data will automatically replace the earliest data when the data storage is full. Plug in a jump drive, the
unit will automatically identify it and start to export the data into the jump drive. While data are being
transferred, press “Minus” (“Cal”), the display panel fl ashes “USB”, which indicates the data are now
exporting and not fi nished yet. After 5 seconds, the display will return to the temperature mode. If the
display shows “ALL”, indicating the data export process is completed. The jump drive can be removed
and it can be plugged into a computer to read the data. The exported data are in the following
formats:
No.
Time
Setting Temp.
Inner Temp.

•Time setting of the record data (the present time setting of system):
Press and hold the “Minus” (“Cal”) key for 10 seconds, “1P” is shown on the display. Press “Set”
(“Cal”) key, and the selection of year is in fl ashing mode. Press “Minus” or “Plus” (“Sensor” or “Cal
cancel”) key to enter the current year, for example, 16, which means 2016. Press “Set” (“Cal”) to save
and confi rm. Next “2P” is displayed, repeat the same process to enter the month. Next repeat the
same process to enter the date for “3P” mode. Repeat the same procedure to enter hour and minute
under “4P” and “5P”. After all entries are completed, press and hold “Set”(“Cal” ) key for 5 seconds or
there is no operation in 10 seconds, the new data will be saved, the control exits back to temperature
mode.
•Note:
Among the setting procedures of aforementioned 1P-5P, parameters can be adjusted selectively
through “Minus” or “Plus”( “Sensor” or “Cal cancel” ) key. For example, if the year(1P) is displayed
in display area, and the year (1P) and month (2P) do not need to be adjusted, reset the date (3P)
directly, you can Press “Plus” (“Cal cancel”) key to choose the date (3P), then press “Set“(“Cal”) key,
at this time, the display area fl ashes date, then press “Minus” or “Plus”(“Sensor” or “Cal cancel” ) key
to adjust the present date, then press “Set” ( “Cal”) key to save and confi rm. When parameter setting
is completed, press and hold “Set” (“Cal”) key for 5s or no operation within 10s to save data and exit
automatically.
USB function module
Before the USB function, please confirm the time of record data of jump drive
interface. If the time does not match, please make an asdjustment using the
aforementioned method.
