Automatic calibration
•Calibration tolerance:
•Automatic calibration output hold:
±0.2% FS Possible
(Example in 4 component analyzer):
CO zero
CO span
O2 zero
NOx, SO2 zero
NOx span
SO2 span
O2 span
Automatic calibration
• Calibration cycle: | Once/day (variable, up to 7 days) |
•Calibration gas feed time:2 to 10 min. (variable), common to each gas
• Display: | Calibration failure | |
| Error code | |

Ordering information
1.Measuring range of analyzer
2.Length of sampling pipe
3.Insertion length of sampling tube
4.Power voltage/frequency
5.Instruction required when standard gas is not necessary
6.Instruction required when individual inspection is not necessary
7.Necessity of spares and supplies (for 1 year)
8.Additional functions
Note: When special functions such as remote range selection, output hold by external contact, auto- matic calibration, automatic calibration start by external contact, insulation output, measured value concentration alarm, etc. are required, they should be separately designated.
