1. Why might measurements with a CS100 or CS106 be bouncing (noisy)?

   Noisy measurements may be caused by several factors:

   • The sensor was not allowed to warm up adequately.
   • The sensor is placed in an electrically noisy environment, which makes other analog measurements noisy.
   • The power supply for the sensor or station is dirty. (There is not a clean regulated voltage.)
2. What is the warm-up time for the CS100 or CS106?

   1 s.

3. Does the CS100 or CS106 fit inside an ENC100 enclosure?

   Either the CS100 or the CS106 can fit inside an ENC100.For more information,refer to the Specifications information on the ENC100 product page.

4. Can a CS100 or CS106 be used to measure pressure in an application at very high humidity without damaging the sensor?

   Yes, but only if certain conditions are met:

   • The sensor resides in a non-condensing environment.
   • The vent tube accessing the high humidity environment is extremely well desiccated to keep any moisture from reaching the sensor’s components. Moisture in the sensor will damage the sensor, often to an un-repairable state.
5. Does the CS100 or CS106 need to be vented to the outside of an enclosure or building?

   In most cases, enclosures and buildings have enough little spaces for the pressure to stay at equilibrium with the outside pressure. Therefore, the sensor does not need to be vented to the outside. It is possible, however, that the rate at which the pressure equalizes is slowed by being in an enclosure, but the rate change usually is not noticeably significant.

   If the sensor resides in an absolutely air-tight environment, and the pressure outside this environment needs to be measured, then the sensor will need to be vented to the outside. However, venting to the outside may change the rating of the enclosure or associated inside environment.

6. How often should the CS100 or CS106 be factory calibrated?

   The manufacturer recommends calibration on a yearly basis. However, conformance to published standards or regulations may require this on a more frequent basis.

7. What are the multiplier and offset values used with a CS100 or CS106?

   For a reading in millibars, the multiplier is 0.240, and the offset is 500. To convert the millibar reading to different units, add an equation to the code.

   To correct the pressure to sea level, see the “Correcting Pressure to Sea Level” section in theCS100 instruction manualor in theCS106 instruction manual. Alternatively, useShort Cut for Windowsto generate the program, and, when prompted, enter the appropriate site elevation.

8. Can a CS100 or a CS106 be enclosed and used to measure air pressure within a snowpack?

   Generally, these sensors are designed to measure the pressure of the environment where they are installed. The CS100 or CS106 can measure the air pressure within a snowpack if the enclosure is adequately sealed away from the snow while allowing the vent to have access to the snow. Note that it may be difficult to accomplish this.

9. If a device or sensor is not available for selection in the Short Cut program, how can it be added?

   It is possible that an older version ofShort Cutis being used. Download thelatest version ofShort Cut.

   If the latest version ofShort Cuthas already been downloaded, open the program.

   1. Go toTools | Optionsand make sure that theEnable Creation of Custom Sensor Filesbox is checked.
   2. In the Generic Measurements folder, right-click the type of measurement to be made for the sensor, and selectCreate Custom Sensor.
   3. Set the fields according to the sensor’s specification, hide those fields that the user does not need to see after being set, and save the custom sensor file settings with theSave Asbutton.
