Model 2010 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%
‘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).
Cur 012ppm HIGH 025ppm OCCUr 2d 15hr 9nn dur 1d 0hr 1nn COHb 00.1% = 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.
Cur 012ppm HIGH 025ppm OCCUr 2d 15hr 9nn dur 1d 0hr 1nn COHb 00.1% CLr
CLr’ = the monitor has been reset.
New 2010 Model CO – Experts Monitor Display
When the test button is pushed momentarily, the display will show the following:
(current Carbon Monoxide level in ppm)
Acc ( Recall Request Accepted )
CO ppm (current ppm level)
(beep 3 times 4 cycles, and red LED also flashes at the same cycles for approx. 10 seconds)
SIL (silenced, if in alarm mode, the buzzer is silenced)
HI ppm (highest previous reading recorded)
xx ppm (returns to current ppm if 7 PPM or more, if not display shows “000”)
On New Model 2010 we no longer have to hold the Test Button down for 6 to 8 seconds to “HUSH / SILENCE it, just touching the Test Button will do it. Also, when you want to CLEAR the Stored Data you simply depress the test button until you see the Green L.E.D. is illuminated, the display will show “CLr” and buzzer will sound a long beep. The COhb memory is cleared.
