TE525MM-LMetric Rain Gage with 9.6 in. Orifice

1. What do the accuracy specifications for the TE525MM-L mean?

   At high-intensity rainfalls, it is likely that the rain will keep pouring into the tipper mechanism while it is tipping, so it will essentially splash out and not be registered. In those instances, there are less tips of the bucket—thus the -3% and -5% listed in the specifications.

2. 降雨/ TE525MM-L窍门是什么?

   The TE525MM-L has a 0.1 mm tip.
3. Are replacement funnels and screens available for the TE525MM-L and TE525WS-L?

   Replacement screens and funnels can be ordered by calling Campbell Scientific.

4. Can one TE525 model be converted to another by exchanging funnels?

   A TE525-L can be converted to a TE525MM-L and vice versa because the inner tipping mechanisms are the same. To convert a TE525-L or TE525MM-L to a TE525WS-L, the rain gage must be sent in to Campbell Scientific to change the tipping mechanism. If an 8 inch funnel is used on a TE525-L or TE525MM-L without changing the tipping mechanism, the multipliers for the rain measurement will change. For information about these multipliers,see theTE525 Instruction Manual.

5. Can a CS705 be used with a TE525-L or TE525MM-L?

   The CS705 Tipping Bucket Snowfall Adapter cannot be used directly with the TE525-L or TE525MM-L because of the funnel size. To make the rain gages compatible, they can either be sent to Campbell Scientific to be converted to a TE525WS-L, or an 8 inch funnel can be installed. If the funnel is used, see theinstruction manualfor the appropriate multipliers, as they will change.

6. What are the indicators that a tipping bucket rain gage is out of calibration?

   Not enough tips or too many tips.

7. What type of wind screen can be used for a tipping bucket rain gage?

   The260-953Alter-type rain gage wind screen consists of 32 heavy metal leaves that hang freely and swing as the wind moves past them. The swinging leaves act as a wind damper and help minimize the effect of wind on the rain measurements without adding additional turbulence.

8. What are the most common errors with a tipping bucket rain gage?

   The most common errors are either that the rain gage appears to have drifted out of calibration or that the tips are not being correctly recorded by the data logger.

9. If a sensor automatically ships with a calibration sheet, what information is included on it?

   The information included on a calibration sheet differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.

10. What are the different cable length choices available for Campbell Scientific sensors?

    Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:

    • An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
    • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

    If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.

    If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.

    • –ET models terminate with the connector for an ET107 weather station.
    • etm模型终止与连接器等107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
    • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
    • –PW models terminate with the connector for a PWENC or pre-wired system.
