12.1. How to check the filament power monitoring signal on SH200-R
Enter the command via serial communication.
13. SAU atmospheric pressure adjustment
Errors due to the altitude of SAU and low atmospheric pressure
*Note*
When using SAU at an altitude of 500m or higher or the atmospheric
pressure of 950hPa or less, adjust the atmospheric pressure.
Adjusting the atmospheric pressure and zero point of SAU enables more accurate
measurements.
Before using a new SAU, or if there is a discrepancy in the indicated value, please
follow the instruction below to adjust them.
13.1.

Atmospheric pressure adjustment of SH200-A

The atmospheric pressure adjustment range is from 0.1V to 2.2V for the output voltage
of SAU and from 7.1×10
range, the atmospheric pressure adjustment cannot be performed.
Please follow the instructions below to adjust the atmospheric pressure.
① Connect a PC or smartphone to the USB connector of the main unit. Run ATM.ADJUST
on the G-TRAN setting tool "UL-MOBI_Android" or "UL-MOBI_Windows".
