Description
Changes the name that corresponds to the sensor on
the top of the measurement screen. The name is
limited to 16 characters in any combination of letters,
numbers, spaces or punctuation.
Lets the user enter the serial number of the sensor.
The serial number is limited to 16 characters in any
combination of letters, numbers, spaces or punctuation.
For pH sensors only—Changes the number of decimal
places that are shown on the measurement screen to
XX.XX (default) or XX.X
Sets the temperature units to °C (default) or °F.
pH sensors—Sets the temperature element for
automatic temperature compensation to PT100,
PT1000 or NTC300 (default). If no element is used, the
type can be set to Manual and a value for temperature
compensation can be entered (default: 25 °C).
ORP sensors—Temperature compensation is not
used. A temperature element can be connected to the
controller to measure temperature.
Sets a time constant to increase signal stability. The
time constant calculates the average value during a
specified time—0 (no effect, default) to 60 seconds
(average of signal value for 60 seconds). The filter
increases the time for the sensor signal to respond to
actual changes in the process.
For pH sensors only—Adds a temperature-dependent
correction to the measured pH value for pure water with
additives. Options: None (default), Ammonia,
Morpholine or User defined.
For process temperatures above 50 °C, the correction
at 50 °C is used. For user-defined applications, a linear
slope (default: 0 pH/°C) can be entered.
For pH sensors only—Sets the isopotential point where
the pH slope is independent of temperature. Most
sensors have an isopotential point of 7.00 pH (default).
However, sensors for special applications may have a
different isopotential value.
Sets the time interval for sensor and temperature
measurement storage in the data log—5, 30 seconds,
1, 2, 5, 10, 15 (default), 30, 60 minutes.
Sets the Settings menu to the factory default settings
and resets the counters. All sensor information is lost.
