• DailyTr Period (Extended Menu only): Period of the daily trend (number of days
used to calculate the gas level variation).
• DayTrAlr L (Extended Menu only): Set point of daily trend Low alarm.
• DayTrAlr LL (Extended Menu only): Set point of daily trend Low-Low alarm.
5.5.3 Temperature Submenu
The Temperature submenu allows the user to:
• Read the current temperature of the Hydran 201 sensor.
• Set the parameters of the sensor temperature alarm.
• Adjust the set point of the sensor temperature.
• Set the periods A and B.
• Read the actual set point, heating power and temperature of the heating plate.
Note: Temperatures displayed on the H201Ti’s display are given in Celsius degrees.
For explanations on the H201Ti’s heating system, see Section 3.6.
The Temperature submenu gives access to the following parameters:
• SensorTemp: Current temperature of the H201 sensor.
• STempAlr LL: Low-Low alarm set point of H201 sensor temperature.
• STempAlr L: Low alarm set point of H201 sensor temperature.
• STempAlr H: High alarm set point of H201 sensor temperature.
• STempAlr HH: High-High alarm set point of H201 sensor temperature.
• TempoAlr Delay: Alarm delay for all above set points.
• Temp SetPoint (Extended Menu only): Set point of the H201 sensor temperature
(average target temperature).
• SP Span (Extended Menu only): Temperature variation according to Temp
SetPoint. For example: the temperature varies between 30 and 40°C (86 and
104°F) if Temp SetPoint is set to the recommended temperature of 35°C (95°F)
and SP Span to 10°C (18°F).
• Period A (Extended Menu only): Modulation period of the temperature variation.
• Period B (Extended Menu only): Reserved for General Electric’s personnel. If the
H201Ti is powered up after a power-down longer than five minutes, the Period B
ceases to affect the gas level fluctuations for two hours, whether its value has
changed or not.
• SP(Actual) (Extended Menu only): Current temperature set point.
• HeatPower (Extended Menu only): Current heating power (in %) of the heating
plate.
• HeaterTemp (Extended Menu only): Current temperature (in °C) of the heating
plate.
