While in Measurement mode press the c key. If the display prompts you to enter the
calibration security code, press the m or . key to set the calibration security code,
then press the [ENTER] key to confirm the calibration security code.
u A flashing "H" shows the ongoing calibration process.
It is possible to select 1 POINT ZERO PT or PROCESS CALIBRATION. Press the [EN-
TER] key after selecting 1 POINT ZERO PT.
u
Enter the value for Point 1 including a decimal point. Ozone is the value being
measured by the transmitter and sensor in the units set by the user. Press [ENTER]
when this value is stable to perform the calibration.
u
After the calibration the slope calibration factor "S" and the offset calibration factor
"Z" are displayed.
u
For ISM (digital) sensors select ADJUST, CALIBRATE or ABORT to finish calibration.
For Analog sensors select ADJUST or ABORT to finish calibration. See Chapter 6
"General Setup" on Page 13
Note: An ozone sensor PROCESS calibration is either a SLOPE or ZERO PT calibra-
tion. The PROCESS SLOPE calibration is always obtained from a comparison instru-
ment or colorimetric test kit. The PROCESS ZERO PT calibration is done in air or in
ozone-free water.
