10.5.3.3 Charging Regulator with Transformer Test 

The procedure outlined in this flow chart tests PS100 and CH100 charging 
regulators that use ac/ac or ac/dc transformers as power source.  If a need for 
repair is indicated after following the procedure, see 

Warranty and Assistance

 (p. 3) 

for information on sending items to Campbell Scientific.
