6.3.6.SETUP Æ RNGE Æ UNIT: SETTING THE REPORTING RANGE UNIT TYPE

The M300EU can display concentrations in ppb, ppm, ug/m3, mg/m3 units. Changing units affects all of the COM port values, and all of the display values for all reporting ranges. To change the units of measure press:

SAMPLE	RANGE=50.000 PPM	CO= XXXX
<TST TST>	CAL	SETUP

Toggled these keys to

select the units of measure for the reporting ranges

	SETUP X.X PRIMARY SETUP MENU
	CFG DAS	RNGE PASS	CLK MORE	EXIT
SETUP X.X RANGE MODE MENU
	MODE SET	UNIT		EXIT
SETUP X.X		CONC UNITS:PPB
	PPB PPM	UGM MGM	ENTR EXIT

EXIT discards the new

setting

ENTR accepts the new setting

NOTE

Concentrations displayed in mg/m3 and ug/m3 use 0°C , 760 mmHg for Standard Temperature and

Pressure (STP).

Consult your local regulations for the STP used by your agency.

NOTE

Once the units of measurement have been changed, the unit MUST be recalibrated, as the “expected

span values” previously in effect will no longer be valid.

Simply entering new expected span values without running the entire calibration routine is not

sufficient.

The following equations give approximate conversions between volume/volume units and

weight/volume units:

CO ppb x 1.25 = CO ug/m3 CO ppm x 1.25= CO mg/m3
