FROM MULTI-GAS CYLINDERS
The T700 is actively

When a concentration mixture is being generated, using a multiple-gas cylinder as a
source the software uses the Diluent and Cal gas flow rates to calculate the actual
concentration for each gas in the cylinder so that it is possible to see the concentrations
of all of the gases being output by the T700 calibrator.
EXAMPLE: For a cylinder containing a blend of CH
contaminant is present in small quantities in bottles containing NO: This will display the
actual concentration being generated for each gas in the multiple-gas cylinder.
When generating a concentration of one of the two primary gases in the cylinder (e.g.
NO or CH4) using the GEN > AUTO, GEN > MANUAL buttons or a preprogrammed
calibration SEQUENCE, press:
MANUAL
<TST TST> GEN STBY ACT>
Continue pressing <TST or TST> until the
MANUAL
<TST TST> GEN STBY ACT>

The ACT> button only appears if the T700 is generating gas from a multiple-gas
cylinder. To start any preprogrammed calibration SEQuences, first place the
calibrator in STANDBY mode (the SEQ button replaces the ACT> button)
For NO cylinders, the instrument will only display the amount of NO
calibration mixture if the concentration of NO
was programmed into the bottle's definition (see Section 3.4.7).
If the T700 calibrator is equipped with the optional O
function allows it to be used as an O
