3.3.  Display Screens 

3.3.1.  Initial Power Up 

When the SZ monitor is first powered up all front panel lights are turned 
ON, and a splash screen appears showing the monitor’s firmware 
revision level. After a brief moment the 

Warm Up 

screen is display 

along with the front panel 

MONITOR ON 

light (green) blinking. 

The monitor takes 15 minutes to warm up; after which, the 

MONITOR 

ON

 light glows steadily and the 

Data Display 

screen is displayed. 

 

 

3.3.2.  Data Display Screen 

During normal operation, the 

Data Display

  screen shows when the 

monitor is performing the following three functions: 

MEASURE

 indicates that the monitor is actively measuring for selected 

gas. In the example screens shown above, the monitor is currently 
detecting 0 ppm of R-134A (refrigerant gas), and that a peak 
measurement of 485 ppm has occurred.  

To reset the peak value to zero, press the 

ENTER

 button. 

PURGE

  is displayed when the monitor is resetting its infrared detector 

to a baseline of 0 ppm using fresh (zero) air that is being drawn in 
through the Purge Air Inlet Port. This purging process is performed on 
an “as needed” basis, which is normally once every 6 to 8 minutes. 

 

 

 

PRES CHK

 is displayed when the monitor is performing an atmospheric pressure check, which is done to 

ensure the accuracy of the gas measurement under varying atmospheric conditions. This pressure check 
is performed every 30 minutes. 

3.3.3.  Function Screens 

The Function

 

screens are used to display stored data and to set up the monitor. 

From the 

Data Display

  screen, press any 

Keypad

  button to display the first 

Function Menu

  screen. 

Next, use the 

Keypad

 buttons to move the arrow (>) on the display until it is next to the desired function, 

and then press the 

ENTER

 button to select that function.  

   

   

 

   

 

 

Once a function has been selected, use the 

Keypad

 to scroll through the displayed data or to change a 

parameter associated with that function. Press 

ENTER

  to save newly entered parameters. Press the 

QUIT 

button to return to the previous screen without saving. 

Note that if no buttons are pressed within 90 seconds after selecting a function, the monitor returns to the 

Data Display

 screen.
