This sections describe the transmitter operation when the clips have excessively high or low resistances 
connected to the pair clips. 

7.4.1

 

Low Current 

 High Resistance or Open 

Low current occurs when the resistive fault is too high or the clips are connected to an Open. Check the 
clip connections when the ST-101 indicates 

Hi Resistance Error

. In some cases, a higher frequency may be 

used and increase the current. 

 

The following table shows the typical fault resistances that can be located.
