| MENU screen | MONITOR screen |
 |
 |
| Monitor, graph display, mode setting, program setting, test name entry, and other menus are displayed. | Specialized in visibility, the operation state and various figures are displayed in a large size. (Pressure indication is equipped as standard.) |
| TREND GRAPH screen | MODE SET screen |
 |
|
| The set program pattern or progress state of a program can be checked on a graph. There is a scaling function that changes the temperature and time scale to make the program pattern easy to see. | Operation mode, execution mode, operation selection, STD / HUM, Exhaust mode can be set. Touching the key changes the screen to the detail setting screen of each item. |

 |
 |
| [ TROUBLE MONITOR screen ] Various alarms are displayed individually. When an alarm is activated, it is displayed in red along with the alarm occurrence date and time. |
[Â Alarm message screen (Troubleshooting)Â ] The causes and measures for generated alarms are displayed on the message. You can restore the state by operating according to the message. |
| ⦿ Two control methods |
  |
 |
| [ HUM / Unsaturation control ]
The unsaturation control mode prevents dew condensation and can set the humidity at any value between 65%RH and 100%RH. In addition, temperature gradients at temperature rise and fall can be set for both fixed value operation and programmed operation, and humidity control is also possible. This mode meets the test conditions defined in IEC 60068-2-66 and JIS C 60068-2-66. |
[ STD / Saturation control ]
This is a 100%RH saturation test mode, and humidity is maintained at 100%RH from a start. This mode is also called as a wet saturation test, and dew condensation occurs on the specimens. A test that corresponds to the conventional saturated type pressure cooker can be carried out. |
| ⦿ Three exhaust modes |
| 1.Slow cooling with humidity maintained mode
After completion of a test, the test chamber is cooled down slowly with humidity maintained until the chamber temperature becomes 100℃ and the chamber pressure drops to 0MPa. This mode can protect specimens from pressure stress and drying that are caused by rapid exhaust. The high accurate test that minimizes the influence on the specimens caused by taking them out on the way can be performed. |
 |
| 2.Cooling with moisture kept mode
After completion of a test, exhaust is not carried out until the chamber pressure reaches 0MPa, and air cooling with a fan minimizes pressure stress and drying. Cooling in a short time compared to the slow cooling with humidity maintained mode is possible. |
 |
| 3.Quick exhaust mode
Immediately after completion of a test, the exhaust valve is opened to carry out exhaust and hot water drainage in a short time. The time from the end of a test to the removal of specimens is the shortest in all modes. This mode is suitable for specimens that are not affected by pressure stress. Data is compatible with the data of a saturated type pressure cooker. |
