7. CALIBRATION AND CALIBRATION CHECK
PROCEDURES
Calibration procedures for the T100H are the same as those for the T100. One exception to this statement is
that the T100H has a special valve option, Zero and Two Span Point Valve Option - OPT 52 (See Section 5.1),
that allows a mid-span point be checked.
7.1. Manual Calibration with Zero and Two Span Valve (OPT 52)
NOTE
It is only possible to calibrate to the high span gas. The low span gas is only used for calibration checks.
Zero and Span calibrations using the Zero and two Span Valve option are similar to that described in Section
7.2, except that:
Zero air and both span gas is supplied to the analyzer through the zero gas and span gas inlets rather
than through the sample inlet.
The zero and cal operations are initiated directly and independently with dedicated keys (CALZ &
CALS)
STEP ONE: Connect the sources of zero air and span gas to the respective ports on the rear panel (see Figure
3-2 of this addendum).
STEP TWO: Set the expected SO
2
high span gas value:
SAMPLE RANGE = 5000.0 PPM SO2 =XXX.X
< TST TST > CAL CALZ CALS SETUP
M-P CAL RANGE = 5000.0 PPM SO2 =XXX.X
<TST TST> SPAN CONC EXIT
SAMPLE SPAN TO CAL:LOW
LOW HIGH ENTR EXIT
M-P CAL SO2 SPAN CONC:80.0 Conc
04000.0 ENTREXIT
The SO
2
span concentration value
automatically defaults to
4000.0 Conc.
If this is not the the concentration of
the span gas being used, toggle
these buttons to set the correct
concentration of the
calibration gase.
EXIT ignores the new
setting and returns to
the previous display.
ENTR accepts the new
setting and returns to
the
CONCENTRATION
MENU.
