OPERATING INSTRUCTIONS

Operation of keys on the control panel
Table below shows the basic procedure for setting the chamber temperature, CO
upper limit alarm temperature setting is also shown in the table. Perform key operations in the sequence
indicated in the table. The example in the table is based on the assumption that the desired temperature
o
is 37 C, CO density is 5% and O
2
executed after the chamber temperature reaches the stable condition.
(The unit is set at the factory so that the chamber temperature is 37
is 20%.)
Allow at least 4 hours until the next setting after setting of desired chamber temperature and setting CO
density to 0%, at the time of first start-up or start-up after no use for long period.
Basic operation (Example: Chamber temperature; 37
Description of operation
1 Turn the power switch ON.
2 Press SET key.
By pressing digit shift key and
3 numerical value shift key, set the
figure to 37.0.
4 Press ENT key.
By pressing digit shift key and
5 numerical value shift key, set the
figure to 05.0.
6 Press ENT key.
By pressing digit shift key and
7 numerical value shift key, set the
figure to 05.0.
8 Press ENT key.
(Executed after the chamber
temperature reaches the stable
condition)

Adjust upper limit regulator so that
the alarm temp. is 1
chamber temperature.
10 Press ENT key.
• In each set mode, if the change of the setting is not necessary, pressing SET key skips to next set
mode.
• When the CO density is set to 00.0% and O

regardless of the chamber atmosphere.
• The upper limit temperature set value will change when the regulator is turned even if the unit is not in
set mode, because the alarm circuit is an independent circuit.
• In each set mode, the indicator returns to the current temperature and density display mode
automatically when 90 seconds has passed without any key operation.
• The setting of CO
