1. Scroll the TEST
function menu until
the NO
X
SLOPE is
displayed.
Scroll the TEST
function menu until
the NO
X
SLOPE is
displayed.
The SLOPE value for NO
X
should be 1.0
0.3. If the value is not in this range, check
Section 7.1 or 9. If the SLOPE value is in the
acceptable range the instrument will perform
optimally.
2. Scroll the TEST
function menu until
the NO SLOPE is
displayed.
Scroll the TEST
function menu until
the NO SLOPE is
displayed.
The SLOPE value for NO should be 1.0
0.3. If the value is not in this range, check
Section 7.1 or 9. If the SLOPE is in the
acceptable range the instrument will perform
optimally.
NOTE: The NO and NO
x
slopes should be
equal within 0.3.
3. Scroll the TEST
function menu until
the
O
2
SLOPE is
displayed.
The SLOPE value for
O
2
should be 1.0 0.3.
If the value is not in this range, check Section
7.1 or 9. If the SLOPE value is in the
acceptable range the instrument will perform
optimally.
4. Scroll the TEST
function menu until
the NO
X
OFFS is
displayed.
Scroll the TEST
function menu until
the NO
X
OFFS is
displayed.
The M200AH will display the OFFSET
parameter for the NO
X
equation. This number
should be near zero. A value of 0.0 50
indicates calibration in the optimal range. If
the OFFSET value is outside this range,
check Section 7.1 or 9.1 for procedures to
correct the OFFSET value to near zero.
5. Scroll the TEST
function menu until
the NO OFFS is
displayed.
Scroll the TEST
function menu until
the NO OFFS is
displayed.
The Instrument will now display the NO
OFFSET value. It should also have a value
near zero (0.0 50).
6. Scroll the TEST
function menu until
the
O
2
OFFS is
displayed.
The Instrument will now display the
O
2
OFFSET value. It should also have a value
near zero (0.0 50).
Step 4 - The M200AH is now ready to measure sample gas.
