Preparing for Operation 

Instruction 3015-4342

Plug the probe connector into the front panel PROBE receptacle  

by aligning the red dots on both the connector and receptacle. Screw the 
desired flexible probe tube (8 or 15 inches) onto the probe assembly. 

 
 

 

The H25-IR is supplied with a 6 foot grounded AC power cord. Make sure 
that an AC power receptacle (socket) compatible with this plug is available 

nearby.  

 
The instrument uses a universal AC power supply that accepts inputs of 100 

to 240 VAC, 50/60 Hz. Power consumption is approximately 15 Watts.  

 
Before connecting the AC power cord, first make sure the instrument’s power switch is OFF. Next, connect 

the power cord to the instrument’s rear panel AC power receptacle, and then plug the power cord into a 

nearby AC power receptacle.  
 

 Explosion Hazard. Do not operate this instrument in the presence of flammable liquids, 

vapors or aerosols. Operation of this instrument in such an environment constitutes a safety hazard. 

 

Turn ON the instrument by setting its power switch, located on the rear panel, to ON.  
 

When power is first applied, the instrument produces one short beep and 

then performs a self-diagnostic check while displaying the instrument’s 
firmware version number (approx. 15 seconds).  

 

Immediately afterwards, the instrument enters its warm-up mode and a countdown from 120 seconds is 
started. In addition, a graphical display of the countdown period is provided by a bar graph that moves 

down the screen during warm-up.  

 
 

 

 
 

At the end of warm-up the Data Display screen appears. This screen shows the current gas measurement, 
leak units, gas type, setup name, range, and mode of operation. In addition, a graphical display of the 

relative gas level is provided by a bar graph that moves up the screen with increasing gas levels. Note that 

the sensitivity of the bar graph is dependent on the Range setting.
