52202 Electrically Heated Rain and Snow Gage 

After mounting the 52202, level the gage and remove the shipping retainer by 
performing the following procedure: 

1.

 

Loosen the three screws that retain housing to base assembly (see FIGURE 

7-1

).  Carefully lift housing free of base. 

2.

 

Remove shipping retainer from bucket.  Verify that bucket tips freely. 

3.

 

Adjust leveling screws until bullseye level is centered. 

4.

 

Replace housing and retighten screws. 

7.3  Wiring 

Disconnect heater power before attempting to service 
or repair this equipment.  Failure to do so may result in 
personal injury or death due to electrocution.  

7.3.1  Heater Wiring 

Attach the power plug supplied with the 52202 by following the instructions 
supplied with the plug.  This gage requires an adequately grounded, reliable 
source of 24 Vac power. 

7.3.2  Wiring to the Datalogger 

When 

Short Cut

  software is used to generate the datalogger 

program, the sensor should be wired to the channels shown on the 
wiring diagram created by 

Short Cut

.  

The 52202 is wired to a datalogger as shown in TABLE 

7-1

.
