The manual mode is also an effec-

tive means to determine if a large 

leak of any refrigerant exists prior to 

searching for leaks (see “Adjusting the 

Sensitivity”).

Manual Mode

  In the Manual Mode the auto-zero 

circuit is disabled. The unit will not zero 

out the leak if the probe is held over 

the leak site. This mode may require 

frequent readjustment of the Manual 

Balance control to maintain the required 

2-3 ticks per second that indicates 

proper adjustment and calibration for 

all three sensitivity switch positions. In 

this mode you may notice sensitivity is 

slightly greater (10-20%) than the auto-

zero mode. This is normal.

Heater Adjustment 

(for optimum performance and calibration)

  The Calibration Reference Bottle sen-

sor heater circuit controls the sensitiv-

ity of the unit. A heat setting that is too 

high causes instability due to excessive 

 sensitivity and shortens sensor life. The 

LOW / OK / HIGH LEDs in conjunc-

tion with the Heater Adjustment and 

Calibration Reference Bottle is a unique 

system for setting the correct sensor 

heat (sensitivity) for optimum perfor-

mance and long sensor life.

  The unit is pre-set for optimum initial 

operation. To check the setting, slide the 

mode switch to AUTO, turn ON the unit 

and allow it to stabilize (approximately 

2 minutes). When stabilized, at 2-3 clicks 

per second, briefly touch the Calibration 

Reference Bottle with the probe (after 

removing the sticky label disc from the 

top of the bottle). If adjusted properly the
