Revision A
25
*USER is a stored sampled concentration saved by the user, to be displayed as 100%.
This value is stored in memory until a new value is sampled and saved by the user.
To set: After completing the setting 100% procedure below, Press the REF button and “USER” will be
displayed. Press <ENTER>, 0 will blink; turn the Selector Valve to CLEAR, and press
<ENTER>.
*HIGH allows sampling of concentrations above 130µg/L, exceeding 200µg/L. This setting should only
be used for sampling quickly and sparingly, as such concentrations will adversely affect the
cleanliness of the optics.
SETTING 100%
Connect Upstream Sample Line & set Selector Valve set to UPSTREAM
<100> <100> key LED flashes
<ENTER> Bar graph scans .The unit averages 100% for a time defined by the L3 setting. When the
<0> LED flashes turn the Selector Valve to Clear.
<ENTER> Sets 0%.
*Note: This setting can be saved by pressing REF, <ENTER>, and resetting 0).
(See *USER above)
Ready for Testing
OPTICS and FLOW LEDS
OPTICS LED: Green - Optics clean. Less than 10,000mg** of aerosol has moved through the scattering
chamber.
Orange - More than 10,000mg, but less than 17,000mg**, of aerosol has moved through
the scattering chamber.
Red- More than 17,000mg** of aerosol has moved through the scattering chamber. It is
strongly recommended that the unit be serviced.
*Note: The unit can continue to be operated by using the SETTING 100% procedure above.
** Note: These values are approximate and may vary depending on the flow and/or the aerosol being used.
FLOW LED: Green- Flow within 5% of 1 CFM.
Orange- Flow within 5% to 10% of 1 CFM
Red- Flow is more than 10% above or below 1 CFM
