Calibration due
Specify number of days for the DO calibration alarm. The
meter shows CAL DUE indicator after calibration date.
Available range : 0 to 30
5 days
Select Pressure Unit Sets the unit for barometric pressure
Available units: mmHg and kPa
mmHg
Measured Pressure Barometric pressure as measured by the instrument.
Adjusted Pressure User adjusted value. -
Pressure
Compensation
ENABLE – The meter will compensate for the barometric
pressure at the location depending on the altitude.
DISABLE – No compensation for the pressure.
(This is applicable only for the % saturation mode. For mg/L
or ppm mode pressure comp. would always be applicable)
ENABLE
NOTE: During measurement, the meter will automatically measure and compensate
for barometric pressure. However, if the user feels that barometric pressure is
inaccurate and needs to be calibrated, it can be adjusted in the DO setup screen.
