Instruction 3015-4256 

Up to 200 refrigerant gas ppm measurements, and 30 alarm and fault events are stored by the monitor.  
To clear stored data, first display the data to be cleared by using the PPM Log, Alarms or Faults 
function (Pages 15). Next, press and hold down the Right Arrow Keypad button, and then press the 

ENTER button. A single, long tone should be heard when the data has been successfully cleared. 

 

In addition to the 24 refrigerant gases available for selection, a custom gas can be added by using the 

CUST K1, K2 & K3 function. Before using this function, the user must contact the factory and provide 
information about the gas to be monitored. The factory will then supply values for K1, K2, and K3, which 

are the coefficients of a polynomial equation that represent the calibration curve of the custom gas. 
From the Data Display screen, use the Keypad buttons to place the arrow (>) on the display next to the 
CUST K1 function. Then press ENTER to display the CUSTOM CAL K^1 screen. Use the Keypad 

buttons to enter the 1

st

 coefficient value (K1) as received from the factory. Press ENTER to save this value 

in memory. 
Repeat the above procedure to enter the values for K2 and K3. 

Select the custom gas for monitoring by using the GASTYPE function (Page 17) and selecting CUSTOM. 
 

 Performing this function will wipe out all program parameters, alarms, faults, and ppm 

log files. 
Press and hold down switch SW3 inside the HGMSZ (Page 8). Cycle AC power OFF then ON. Listen for 

beep and then release switch. If needed, reprogram the HGMSZ to the desired settings.
