Setup & Configuration4Figure 4-13. Utility Program - Choose Options ScreenFrom this screen you will select the main operating settings for your end device.NOTE:Each end device must have a different address number forproper operation.After making your selections click the “Next ” button to proceed and programyour settings into your unit.(1) Backlight OptionsIntensityHere you can set how bright you want the backlighting to be when on. Keep inmind that when used under battery power the led brightness has a direct effecton the life of the battery. Keep to the lowest setting possible for your ambientlight conditions to conserve of battery power.External PowerHere you can set the amount of time you want the backlighting to stay on whenactivated and the unit is running on external power.NOTE:You can only set the backlighting to be “Always On” whenthe unit is powered by an external power supply.When set to 60 or 300 seconds the backlight will come on and then turn off afterthe allotted time has expired.4-8
4Setup & ConfigurationBattery PowerHere you can set the amount of time you want the backlighting to stay on whenactivated and the unit is running on battery power only.NOTE:You can not set the backlighting to be “Always On” when theunit is powered by battery power.When set to 10 or 30 seconds the backlight will come on and then turn off afterthe allotted time has expired. If backlighting is not required it is recommendedthat you select “Always Off” to preserve battery life.(2) Sensor OptionsSample IntervalHere you can set how oftern the device samples the sensor and updates the LCD.NOTE:The sample interval is always fixed at 0.382 seconds/sample(2.6 samples/second) when powered externally, regardless ofthe setting in the Configuration Wizard. The purpose of thesample interval setting is for conserving battery life, not fordisplay damping or averaging, and therefore has no effectunless operating on battery power only.RTD AlphaSelect the proper curve for the sensor or probe you will be measuring with your unit.NOTE:If you ordered a unit with an integral probe, this setting willbe factory locked to match the probe installed.(3) Front Panel OptionsShow Decimal PointSelect this option to turn on or off the last digit and decimal pointDisable Bar GraphSelect this option to remove the bar graph indicator from the display.(4) Alarm OutputAlarm OnDisabled - The alarm output is disabled and will not operate.Rising - The alarm output activates ONLY when the temperature meets orexceeds the High Setpoint.4-9Falling - The alarm output activates ONLY when the temperature meets or fallsbelow the Low Setpoint.
