Caution : The initial calibration before delivery of the product is performed by Senko Co. Ltd.

As the calibrated values are stored in the device, incorrect calibration may reduce the

accuracy of the product. Calibration is to be performed on monthly or quarterly basis in

general. However, it can be adjusted depending on the frequency of use of the device.

icons shall blink if buzzer key is pressed for 3 seconds under the state power key is pressed

simultaneously. Press power key at this state to enter into standby calibration mode. Calibration

shall be completed in 10 second while processing countdown from 10,9,8…down to 3,2,1. When

calibration is successfully completed, it returns to Gas Measure Mode with alarm sound after the

icons being blinked for 3 seconds. In case standby calibration is failed, it returns to Gas

Measure Mode with alarm sound after the

icons being blinked for 3 seconds but the

icons

shall remain appeared in this case. If such occurrence happens repeatedly, please contact our
