Field Calibration
• Installation Space
A secure installation location that meets the dimensional requirements as shown in the drawing below is nec-
essary to install the Field Calibration System. Before using the Field Calibration System, a “Calibration Area”
for stable and high quality calibration is required, in addition to the place that is necessary to position the Field
Calibration System.
• Calibration Area
The “Calibration Area” is the box shaped area shown in the drawing below.
The dimensions are:
• 30 cm or less in front of or behind the Chart unit
• 20 cm or less right or left to the Chart unit
• 20 cm or less above the Chart unit
Note
• Prevent foreign matter from getting into the “Calibration Area”. When executing Field Calibration, do not allow
workers into the area. It may result in incorrect calibration.
• Be careful to block incident light from the outside. Execute Field Calibration under fluorescent light at less than
500lx.
• Prevent light from windows.
