Problem 

Possible Causes 

Remedies 

2. LED on Pilot 
Probe does not 
illuminate. 

Probe battery is dead or 
installed incorrectly. 

Replace with new battery. 

Verify that battery was inserted 
correctly into probe (

‘+’ should face 

toward base of probe). 

Battery was not installed. 

Install new battery. 

LED on probe is damaged. 

Contact Dilon Technologies for 
assistance. 

 
Table 8A-3. Control Unit with CABLED PROBE- Settings and Indicators  

Problem 

Possible Causes 

Remedies 

1. Zero in display. 
No signal under 
presence of a 
radioactive source. 

No connection between 
probe, cable, gain module (if 
present), and control unit. 

Check that all connections are secure. 

Isotope control is set to 
incorrect isotope. 

Change Isotope Control (on back of 
control unit) to Tc-99. 

Gain module, if used, is set 
to zero. 

Run Peak Procedure (Sec. 7A). 

There is an open circuit in 
the probe cable. 

Replace cable. 

Circuit inside the control unit 
has been damaged. 

Try a different control unit. Contact 
Dilon Technologies for assistance. 

Probe is damaged / probe 
cap not secure / detector 
damaged. 

Try a different probe or contact Dilon 
Technologies for assistance. 

2. Spurious high 
counts, such as 
80,000 counts a 
second (when probe 
is held in air, for 
example). 

Intermittent short in the 
cable. 

Replace cable.
