9.2.3. PERFORMING A BASIC MANUAL CALIBRATION  
The following section describes the basic method for manually calibrating the 
T300/T300M. 
If the analyzer’s reporting range is set for the AUTO range mode, a step will appear for 
selecting which range is to be calibrated (LOW or HIGH). Each of these two ranges 
MUST be calibrated separately.   
I
MPORTANT
 
I
MPACT ON 
R
EADINGS OR 
D
ATA
 
If the ZERO or SPAN buttons are not displayed during zero or span 
calibration, the measured concentration value during this time is out of 
the range allowed for a reliable calibration. Refer to Section 11 fo

troubleshooting tips. 
 
9.2.3.1. SETTING THE EXPECTED SPAN GAS CONCENTRATION 
Note 
When setting expected concentration values, consider impurities in your 
span gas. 
The expected CO span gas concentration should be 80% of the reporting range of the 
instrument (see Section 5.4.1). 
 The default factory setting is 40 ppm.  To set the span gas concentration, press:
