Notes: 1. Battery backup time depends on run mode and frequency of transmission. 2. Limited by lithium ion charging temperature. Lower temperature operation will require external or internal heating to maintain sufficient battery temperature for charge acceptance. Contact the manufacturer for more information.

Sensor Maintenance and Calibration Periodic Maintenance: The SPOD is a low maintenance device and is designed to operate remotely with no user intervention. Occasional inspections for damage and cleanliness are recommended to maintain optimum performance. Sensor Calibration: Depending on application requirements and environmental conditions, periodic calibrations may be required to maintain target accuracy.

3) Click ‘Options’ as shown below a. ‘Serial Port’ options should open by default. If not, select Serial Port options from the list of available options as shown below. All default options should be correct but please verify. Click on ‘Port’ dropdown list and make note of any available ports.
Page 28
b. Select ‘Terminal’ options from list of available options and select ‘Line Mode’ as shown below. Line mode adds a text entry bar at the bottom of the screen that is useful for sending commands to the connectedsensor.
