Instrument Configuration

Continuous Mode Description
The continuous mode is typically used for process
measurement.
Continuous mode cycle:
• Measurements are taken every 2
seconds.
• Relays and analog outputs are regularly
updated.
• Measurements are stored continuously in
volatile and non-volatile memory.
• Measurement mode is locked on
Continuous for on line processes
• Selection of units for barometric pressure
and temperature

Measurement Configuration

• Sensor's membrane number selection
• Medium: Liquid or Gas Phase
• Gas unit type: Partial, Fraction, Dissolved
• Gas unit: The list of available units
depends on unit type selected above
• Liquid: When medium is liquid, select
water or a liquid with a different solubility
(if available)
• Display resolution: Maximum resolution
depends on gas, membrane and unit. A
maximum of 5 digits can be displayed.
Decimals can be limited to 0, 1, 2 or 3
decimals for easier reading.
• Thermal cutoff: To protect the sensor, the
thermal cutoff function allows for setting a
sample high temperature limit. If
exceeded (during a Cleaning in Place
cycle for example) the electrical signal to
the sensor is cut off, the measurement
session is suspended and the system
displays a "HOT" alarm message. The
system resumes when the temperature
drops to 90% of the specified cutoff
temperature.
