The hood flow calibration factor is applied when the offset factor is changed. There is no
option to select USEr or FACt calibration for hood flow measurement. Set value to 1.000 to
restore factory calibration.
Connect and Download Data to an Optional Printer
To connect a printer, use the RS232 printer cable supplied with the optional printer. Note that the printer
interface cable is different from the computer interface cable.
The printer must be set to the same baud rate as the instrument. To change the baud rate of the printer,
refer to the printer’s operations manual. Always turn the instrument on before the printer. If the printer
prints question marks (??????), asterisks (******), or random characters, reset it by turning it off and then
on again.
