READ FIRST BEFORE OPERATION

The

 Multi Gas Clip Simple Plus 

is a personal safety device designed to detect 

the presence of hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2) 

and combustible gases (LEL). Before operation, ensure that you have been 

properly trained on the use of the detector and the appropriate actions to take 

in the event of an alarm condition.

Turning On the Detector 

Once activated, the detector will run continuously for 36 months. To activate, 

press and briefly hold down the power/menu button. Once activated, the 

detector will begin to display Gas Readings (5) immediately. Each Gas

Identifier (6) will show a chasing “0” for the Gas Reading (5) while it is 

stabilizing and self-testing. Once all Gas Identifiers (6) have completed the 

warm up and stabilization sequence, <65 seconds, the detector is ready to 

detect all applicable gases. Display will show:

Bump Testing and Calibrating 

These operations can be performed manually or automatically using the 

MGC Simple Clip Dock

. Refer to the 

Multi Gas Clip Simple Plus User’s 

Manual

 for instructions.

Auto Zeroing

Continuously hold down the power/menu button to auto zero the detector. 

Display will show “ZERO” and count down from 3 to 1, followed by “ZERO OK”. 

Release button when display shows “ZERO OK”. The display will change to 

“AUTO ZERO”. Wait a few seconds, then press the button briefly when display 

shows “APPLY GAS”. Detector has been successfully auto zeroed.

When a Gas Reading (5) exceeds its alarm threshold, the detector will go into 
visual, vibrating and audible alarm. On the display, the   icon will appear 

beside the Alarm Condition (1) and the associated Gas Identifier (6) will flash 

off and on continuously. 

 Warning

 - Users must familiarize themselves with the icons in both 

 

alarm and non-alarm states.

 Warning

 - If the display is missing icons, or cannot be clearly read, 

discontinue use and contact Gas Clip Technologies.

 Warning - 

The IR LEL sensor will not detect hydrogen (H2) or acetylene 

(C2H2) gases however, due to their cross-sensitive nature, the CO sensor 

 

will go into alarm well below 10% LEL.
