Model 1070 CO-Experts Digital Display and Recall Features

One of the most important features of the CO-Experts Carbon Monoxide alarm is the ability to recall exposure history.

When the "TEST/RESET" button on the front of the monitor is depressed, the following information is displayed:

Cur  012ppm    HIGH  025ppm     OCCUr  2d 15hr 9nn     dur  1d 0hr  1nn     COHb  00.1%      

Where:
  • 'Cur'         =   

 

the current level of CO (in this example, 012ppm or parts per million).

 
  • 'HIGH'      =
 the highest CO level since the instrument was 'cleared' last (in this example 025ppm).
 
  • 'OCCUr'   =

 

 how many days (d)  hours (hr) and minutes (nn) ago the high reading was recorded (in this example 2 days, 15 hours, 9 minutes ago).
  • 'dur'          =
 the length of time the high level was recorded (in this example, 1d 0 hours, 1 minute).
 
  • 'COHb'      =
  

the approximate percentage of oxygen that would have been displaced by carbon monoxide in the human body.
 

When the "TEST/RESET" button is depressed until after you have heard the second series of four "Beeps" (approximately twelve (12) seconds) the above information is displayed, and is then followed by a long single "Beep", and the display will show "CLr".  This clears the instrument and erases the stored data to "000", and the display will return to "Blank", or the actual PPM of carbon monoxide present if it is 10ppm or more.
